[f0086]

Continuation of #707 — closes #615. Huge thanks to @kushpvo for the bulk of this work (API keys, handler, spec generation, UI); this PR reworks the review-requested parts and rebases onto the latest main.

What it adds

A versioned public REST API at /api/v1 for integrations (e.g. budgeting tools):

• Auth: API keys created in Account → API keys (SHA-256 hashed, spro_ prefix, optional expiry). Authorization: Bearer spro_… (or X-API-Key). Keys act with the user's permissions; every endpoint and write path runs the same checks as the app, including group membership.
• Endpoints (13 + upload): user.me, user.getFriends, user.getOwnExpenses, user.getBalancesWithFriend, user.getFriend, group.getAllGroups, group.getGroupDetails, expense.getBalances, expense.getAllExpenses, expense.getExpensesWithFriend, expense.getGroupExpenses, expense.getExpenseDetails, expense.addOrEditExpense, plus POST /api/v1/upload for receipts. List endpoints use the app's cursor pagination (limit + cursor, nextCursor in the response). Key limit configurable via API_KEYS_MAX_PER_USER.
• Docs: build-time generated OpenAPI 3.1 spec (static type analysis via @trpc/openapi) served at /api/openapi.json, interactive Scalar UI at /api/docs (bundle pinned with SRI). User-facing docs in docs/API.md (incl. which procedures are not exposed yet and why, and the health checks).
• Formats: plain JSON in/out matching the generated spec (BigInt → number, Date → ISO string). Amounts additionally accept numeric strings (full precision beyond Number.MAX_SAFE_INTEGER) and ISO date strings; native superjson envelopes also accepted for tRPC-client compatibility.

Architecture (per review discussion)

• Router files now export plain method records (userMethods / groupMethods / expenseMethods) and build their t.router(<record>) from them — the existing procedure code is untouched. apiRouter mounts a curated subset via a typed pickMethods helper, so each procedure exists exactly once and new public endpoints are one line.
• The API gets a dedicated initTRPC instance (apiTrpc.ts) with its own plain-JSON transformer (apiTransformer.ts), so mounting app procedures in the API router can never affect /api/trpc serialization (fixes the PR's shared-_config mutation, which leaked the transformer into the app router because both instances shared the config object).
• The API's addOrEditExpense shares one upsertExpenses write path with the app procedure — permission checks (group membership/archived, deleted expense handling) are inherited from main instead of being duplicated by the API.

Review feedback addressed

krokosik

• router processing in the generator → curated method records, @trpc/openapi walks the real (narrow) types — spec is generated from exactly what is mounted
• keep openapi.generated.json in sync → .husky/pre-push regenerates and aborts stale pushes; pnpm build also regenerates
• ApiKeys.tsx i18n → account.api_keys.* keys (English only, Weblate picks up the rest); account page label translated too
• isPlainValue → coerceQueryParam in src/utils/queryParams.ts (not the tRPC client entry)
• "Biome?" post-processing → typed with guards, no TODO comments
• expiry configurable in the UI → optional date picker; synthetic session.expires mirrors the key's expiry (expired keys → 401)

CodeRabbit

• shared transformer config mutation → isolated tRPC instance
• plain-JSON POST failing on bigint/date → coerced input schemas (apiAmountSchema, apiDateSchema union coercion)
• limit/offset not integers → .int().min(1).max(100) / .int().min(0) (safe)
• relative server URL in spec
• unpinned Scalar CDN → exact 1.76.0 + subresource-integrity hash + crossorigin
• onOpenChange instead of onClose in ApiKeys (plaintext key now also cleared on desktop)
• group-membership / deleted-expense checks in the write path → shared upsertExpenses (writes are rejected with 403/404 like the app)

Verification

• prettier --check, lint, tsc --noEmit, unit tests (475), integration tests (15) and build all pass
• End-to-end smoke-tested against a dev server: 401 without/with expired key, plain-JSON responses and POSTs, pagination defaults + fractional-limit rejection, superjson-envelope POST, non-member group access → 403, /api/trpc still superjson-encoded

Not carried over from the original PR: .opencode/package-lock.json (local artifact) and a duplicate weak upsertExpenses/createExpenseSchema copy (main's validated shared path is used instead).

Summary by CodeRabbit

• New Features
  • Added a REST API for user, group, and expense data, including paginated expense listings and expense updates.
  • Added account settings to create, copy, view, and revoke API keys, with optional expiration dates and usage details.
  • API requests support bearer-token or API-key authentication and follow the caller’s permissions.
  • Added an interactive API reference with endpoint details and request examples.
• Changes
  • Removed the account-deletion option from account settings.
  • Expense listings in the app now return all matching expenses instead of using cursor-based pagination.
• Documentation
  • Added guidance on authentication, request formats, pagination, supported endpoints, and monetary values and timestamps.

Merge Risk: High · up to 4bb85

This branch appears to undo recent main-branch changes alongside the new API. Removing the user deletion field can break sign-in session checks and account deletion. A missing export blocks the build. Expense lists, group pages, and balances no longer match what the app expects. The public API can also expose other users' records and accept keys from deleted accounts. These should be fixed before merging.

Remove the useCallback wrappers from the event handlers.

The repository guidelines prefer plain components with colocated handlers. React Compiler handles routine memoization. useCallback is for cases where profiling or an identity requirement justifies it. onCreate, onRevoke, and copyKey have no such requirement. This component contains no BigInt literals, so the compiler should optimize it.

Convert the three handlers to plain async arrow functions and drop the dependency arrays.

Use arrow functions for the new exported helpers.

The repository guidelines prefer arrow functions over function declarations. This file declares six helpers with export function (hashApiKey, generateApiKey, parseApiKeyFromHeaders, isApiKeyExpired, resolveApiKeyUser, toSessionUser). Convert them to export const name = (...) => .... The [trpc].ts handler and scripts/generate-openapi.ts use the same pattern.

The SHA-256 hash without a server secret is acceptable here. The key is 256 bits of randomBytes, so there is no low-entropy input to brute-force.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Coerce decimal integer query values before pagination validation.

GET /api/v1/expense.getAllExpenses?limit=01 passes "01" to coerceQueryParam, which leaves it as a string. paginationInput requires a number, so validation rejects the request before the procedure runs. Coerce decimal integer strings only. Keep non-numeric values unchanged.

Minor · Returned API amounts above Number.MAX_SAFE_INTEGER lose precision. · apiTransformer.ts:49-63

src/server/api/apiTransformer.ts:49-63
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Returned API amounts above Number.MAX_SAFE_INTEGER lose precision.

toPlainJson converts every bigint with Number(value), so an amount such as 9007199254740993n is returned as 9007199254740992. The v1 API accepts such amounts as numeric strings. It also documents them in its input comment. The output and input sides therefore do not match. Clients that read these amounts receive a wrong monetary value, and no error is returned.

The trigger requires an amount of about 2^53 cents or more. That is roughly 90 trillion currency units, so the impact is narrow. The stored value stays exact. The loss happens only in the response.

Suggested fix

 const toPlainJson = (value: unknown): unknown => {
   if ('bigint' === typeof value) {
-    return Number(value);
+    // Keep unsafe integers exact. Number() rounds them.
+    return Number.isSafeInteger(Number(value)) ? Number(value) : value.toString();
   }

This keeps safe amounts as numbers. Unsafe amounts become decimal strings, which match the string input the API already accepts. The OpenAPI schemas for these amount fields declare type: integer. They must also accept a string for values above the safe range. Update the schema generator with this change.

Minor · Document the X-API-Key header in the generated OpenAPI security… · generate-openapi.ts:83-111

scripts/generate-openapi.ts:83-111
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Document the X-API-Key header in the generated OpenAPI security schemes.

The generator declares only bearerAuth, but the /api/v1 API accepts X-API-Key as well. Clients that read /api/openapi.json or use the docs "Authorize" button never see the header method. The correction belongs in scripts/generate-openapi.ts. Editing openapi.generated.json directly is not enough, because the next regeneration overwrites it.

Suggested fix

   doc.components.securitySchemes = {
     ...doc.components.securitySchemes,
     bearerAuth: { type: 'http', scheme: 'bearer', description: 'SplitPro API key (spro_…)' },
+    apiKeyHeader: {

   };
-  doc.security = [{ bearerAuth: [] }];
+  doc.security = [{ bearerAuth: [] }, { apiKeyHeader: [] }];

Regenerate src/server/api/openapi.generated.json after this change. The security array uses two entries, so either scheme satisfies the requirement.

@krokosik @alexanderwassbjer — the PR is ready for a final look. Since your review of #707, it's been rebased onto current main and all review feedback is addressed: a curated method-record surface (only what's mounted in apiRouter is public), a dedicated tRPC instance with a plain-JSON transformer so /api/trpc is unaffected, intended-format input coercion, integer pagination with unique tie-breakers, and i18n'd key management with optional expiry. Everything is verified end-to-end (unit + integration tests, build, live smoke test) and CodeRabbit's threads are all resolved. Happy to make any adjustments.

[alexanderwassbjer]

Nice work overall. Some comments added

[f0086]

Thanks for the review, @alexanderwassbjer! All 7 comments addressed in commit 85f730f (pushed to feat/trpc-openapi-finish):

1. @trpc/openapi location — moved from dependencies to devDependencies (build-time only). Kept 11.18.0-alpha; peer-dep upgrade can be a follow-up.
2. build script — reverted to next build. gen:openapi still available via pnpm gen:openapi and pre-push hook.
3. pre-push hook — now only runs pnpm gen:openapi when src/server/api/** changed in the pushed range.
4. BigInt precision — values within MAX_SAFE_INTEGER stay number; larger values serialize as string to match input. Test added in apiTransformer.test.ts.
5. coerceQueryParam test — added test documenting number/boolean coercion edge case (?name=123 → number, ?name=true → boolean).
6. Expiry timezone hint — added expires_hint translation key rendered below the date input in ApiKeys.tsx.
7. linguist-generated — added .gitattributes marking openapi.generated.json as linguist-generated=true.

Pre-merge checks (prettier, lint, tsc, tests, build) pass on this branch. Ready for final look whenever you are.

Fixed in commit 37ee3c9: the pre-push hook now reads the actual push range from stdin (local/remote SHA per ref) and checks every commit being pushed, not just HEAD~1..HEAD. This ensures API changes in any commit of a multi-commit push are caught.

Fail the hook when OpenAPI generation fails.

When API files change, pnpm gen:openapi runs without an exit-status check. A failed generation can then reach git status --porcelain; if the generated file is unchanged or absent, the hook exits successfully and allows the push without a valid generated spec.

Suggested fix

-  pnpm gen:openapi
+  pnpm gen:openapi || exit 1

Update the OpenAPI generation step in the pre-push hook so a nonzero exit from
`pnpm gen:openapi` immediately fails the hook. Keep the generated-file status

Fixed in commit 4bb8557: the pre-push hook now reads the actual push range from stdin (local/remote SHA per ref) and checks every commit being pushed, not just HEAD~1..HEAD. This ensures API changes in any commit of a multi-commit push are caught.

Update: Also rebased the entire PR onto current main (28ee49a) to resolve merge conflicts with #787 (account deletion) and #789 (infinite scroll). The branch now has 4 clean commits on top of main.

Summary of Changes

All CodeRabbit review comments have been addressed:

✅ Fixed (commit 4bb8557)

The pre-push hook now correctly checks every commit in the push range by reading from stdin, not just HEAD~1..HEAD.

✅ Rebased onto main

The PR has been rebased onto current main (28ee49a) with all merge conflicts resolved:

• Integrated with feat: add self-service account deletion with preserved shared history #787 (account deletion feature)
• Integrated with fix: load activity and expense histories with infinite scrolling #789 (infinite scroll with cursor-based pagination)
• The API's offset-based pagination coexists cleanly with the app's cursor-based pagination

Commit History

1. dc8ab0e - Main feature: Public REST API with API-key auth and OpenAPI docs
2. c0b06e7 - Stable pagination order, docs sign convention, pre-push check
3. c2234aa - Address @alexanderwassbjer review comments
4. 4bb8557 - Fix pre-push hook to check all commits in push range

Ready for final review! 🚀

Correction: branch rebuilt on current main (cd94fca)

My previous comment said all CodeRabbit findings were addressed. That was wrong. The rebase onto 28ee49a in 4bb8557 resolved conflicts in favour of the old PR code, so the diff silently reverted #787 (account deletion) and #789 (infinite scrolling). That is what CodeRabbit's "Restore …" findings were pointing at.

I rebuilt the branch by replaying the original commits onto current main (036d5f0, including #792 and #793). Against main, the PR is now additive: it no longer touches User.deletedAt, DeleteAccount, or the cursor pagination of the app procedures. The accidentally committed .serena/ cache files are gone as well.

Follow-ups for the features that landed on main in the meantime

• Account deletion: API keys of deleted accounts are rejected (resolveApiKeyUser), and deleteAccount removes the user's API keys. A test covers it.
• Cursor pagination: the app procedures keep main's cursor pagination. The public API keeps its separate offset-paginated variants, now imported as apiPaginationInput to avoid clashing with ~/utils/pagination.
• Future-expense balances (fix: optionally exclude future expenses from balances #793): the API context is built with createInnerTRPCContext, including the time zone header, so balanceProcedure behaves the same on /api/v1.

Other fixes

• Pre-push hook: checks every pushed ref, skips deletions, treats an unknown remote SHA as "check", fails if gen:openapi fails, and compares against the pushed commit instead of the working tree.
• CI: check.yml now regenerates the spec and fails if openapi.generated.json is stale, so the hook is no longer the only guard.
• Lockfile: pnpm-lock.yaml is in sync again after moving @trpc/openapi to devDependencies.
• Tests: fixed a type error in apiTransformer.test.ts.

The user.ts findings (duplicate procedures, a balance query that mixed currencies, the missing friend check) came from the bad merge and no longer apply. Type checking, lint (no errors) and formatting pass, and all 535 tests pass.

One of the inputs is offset in the API creation modal

Nitpick, can something be done to make these models have more semantic names? Or maybe we should just hide them?
