Adds a veriql action provider with three actions for agents that move money:

• check_payee: call this before a transfer. It checks the recipient against US Treasury OFAC SDN, the Drain Watch scam-address list, and Tether/Circle freeze status (read from the issuer contract). It returns do_not_pay, no_known_risk or incomplete.
• check_signature: call this before signing. It decodes approve, Permit, Permit2, EIP-7702 delegations, transfers and revokes, and returns block, warn or allow. An undecodable payload returns block.
• check_denylist: a free, keyless lookup against the same lists.

The paid actions pay $0.005 per call over x402 from the agent's existing wallet (Base or Solana USDC), using the same @x402/fetch client and registerExactEvmScheme/registerExactSvmScheme wiring as the existing x402 provider. A payment policy refuses any option above a configurable cap (default 0.01 USDC) before signing. An optional API key (VERIQL_API_KEY) skips x402 entirely.

Any failure is returned as an error telling the agent to treat the input as unverified. A failure never reads as a clean result.

The provider is read-only: it never requests keys and never signs anything except the capped x402 payment.

Checks

• npx jest src/action-providers/veriql: 12 passed
• eslint, prettier --check and tsc --noEmit: clean
• Changeset included (@coinbase/agentkit patch)

A standalone build of the same provider is published as veriql-agentkit for anyone on an older AgentKit.

Side note, unrelated to this provider

While testing, the analytics call that the action decorator fires (to cca-lite.coinbase.com) is not awaited or caught, so when that request fails the process logs an unhandled promise rejection. Happy to open a separate issue if useful.
