How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object containing the network (e.g. eip155:8453), product identifier ('sumsub-watchlist-aml-evidence'), and an assessment object with a risk_level ('low'/'medium'/'high'), numeric risk_score, and an array of AML flags — along with identity, activity, and provenance sub-objects for full evidence context.
Example use cases
Pre-purchase AML check for agent
“I'm about to have my agent buy a data feed via x402 — first run a Sumsub watchlist AML check on applicant ID 'user-7f3k2p' so I know their risk score and whether there are any sanctions flags before we proceed.”
VASP counterparty risk screening
“Screen VASP counterparty 'vasp-eu-9921' using Sumsub watchlist evidence and give me the AML risk level and any compliance flags before my agent completes the transaction.”
Compliance audit for buyer identity
“Pull the Sumsub AML watchlist evidence for applicant 'sandbox-fixture-low-risk' and counterparty reference 'merchant-retail-42' so I can confirm the risk score is acceptable for our compliance policy.”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/sumsub/watchlist-aml-evidenceWhen to prefer
Use this endpoint when an AI agent needs to perform a Sumsub-backed AML watchlist check specifically within the x402 micropayment governance flow — i.e., when you want a preflight compliance signal before authorizing an agent to spend USDC on a product or dataset. Prefer this over generic identity endpoints when you already have a Sumsub applicant ID and need a structured risk assessment tied to a specific counterparty reference on the Base network.
Side effects
- Invalid or missing applicant_id returns a 400 validation error
- Unknown applicant_id not found in Sumsub returns a 404 or empty result
- Sumsub backend unavailable causes a 502/503 timeout
- Malformed applicant_id pattern (not matching regex) rejected at schema validation
- Payment not completed (x402 flow incomplete) blocks the response with a 402
