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 identifier (e.g. eip155:8453 for Base), a product string ('nomos-value-usdc-twd'), and an assessment object with risk_level (e.g. 'low'), a numeric risk_score, and a flags array listing any detected risk indicators. Additional fields for identity, activity, and provenance may also be present.
Example use cases
Pre-trade risk check for USDC/TWD
“I'm about to exchange 100 USDC for Taiwan dollars — can you do a quick Nomos risk assessment on the USDC/TWD pair first and let me know if the risk level is low or if there are any flags I should know about?”
Automated agent safeguard before payout
“Before my agent sends a USDC payment that gets converted to TWD, run a Nomos value preflight check on the USDC/TWD pair with the default 1 USDC amount and only proceed if the risk score is zero and there are no flags.”
Compliance screening for stablecoin conversion
“I need to confirm there are no compliance flags on a USDC to TWD conversion — can you call the Nomos USDC/TWD risk API for a 25 USDC amount and show me the full assessment result?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/x402/v1/value/usdc-twdWhen to prefer
Use this endpoint when an AI agent or automated workflow needs a lightweight, pay-per-request risk preflight on a USDC-to-TWD value operation before executing it. It is best suited for Base network transactions and situations where you need a structured risk_score and flags output without maintaining a persistent risk-engine subscription. Prefer this over generic fraud APIs when you specifically need TWD currency-pair context on the Base blockchain.
Side effects
- Missing or malformed 'amount' query parameter returns a validation error
- Non-numeric or negative amount values are rejected
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Network or Cloudflare Worker downtime results in a 503 or timeout
- Amount exceeding allowed range may return an error or unexpected assessment
