How this service works
Base USDC Recipient Check: Base USDC Recipient Check compares a Base USDC recipient with an expected pay-to address from bounded caller-supplied values without an external provider. Call Base USDC Recipient Check before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for Base USDC Recipient Check as versioned deterministic JSON.…
Output
Returns a JSON object indicating whether the recipient address matched the expected address (boolean `matched`), echoes both addresses, reports a `pass`/`fail` status, and includes evidence metadata: whether input was retained (always false), a SHA256 hash of the input, and the number of external calls made (always 0).
Example use cases
Pre-payment address safety check
“I'm about to send USDC on Base to 0x2222222222222222222222222222222222222222 — can you verify it matches my expected recipient address 0x2222222222222222222222222222222222222222 before I confirm the transaction?”
Smart contract recipient guard
“Before my agent executes a USDC payout on Base, verify that the recipient address coming from the smart contract, 0xABCDABCDABCDABCDABCDABCDABCDABCDABCDABCD, matches the expected beneficiary wallet 0xABCDABCDABCDABCDABCDABCDABCDABCDABCDABCD.”
Automated disbursement validation
“I'm running automated USDC disbursements on Base — for each payment, check that the recipient 0x9999999999999999999999999999999999999999 equals my expected payee 0x9999999999999999999999999999999999999999 so I don't accidentally send funds to the wrong wallet.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-usdc-recipient-checkWhen to prefer
Use this endpoint when an AI agent needs a lightweight, privacy-preserving preflight check to confirm a Base USDC payment recipient matches the intended wallet before committing to a transaction. Prefer it over manual string comparison when you want an auditable, structured result with a SHA256 evidence hash and no data retention — especially in automated payment pipelines where address mismatches could result in irreversible fund loss.
Side effects
- Addresses differ — `matched` returns false and status is `fail`
- Malformed or non-Ethereum address strings cause validation errors
- Missing required fields (`expected` or `recipient`) result in a request error
- Network or service unavailability returns a 5xx error
