How this service works
Tools for x402 sellers and buyers, paid per call in USDC by the agents that use them. For sellers: a listing lint and a 402 conformance run, a Bazaar rank check, a Machine Buyer Panel that tests whether buyer agents pick your offer over its rivals, signed samples, Fair Offer certification, a model-update watch, and a demand gap finder for what to build next. For buyers: a signed Buyer check on any offer before paying (or settlement proof after), a buyer drill that red-teams an x402 client against nine traps, a wallet overspend audit, and free checks of any seller's offer. Every paid tool has a free sample. Agoranome pledges 15% of settled revenue to a cause.
Output
Returns a drill session object containing a session token, a list of nine adversarial trap definitions (each with ID, URL, description, pass condition, and listed price), a drill ID, session status, expiry timestamp, and token-gated URLs to close the drill and retrieve the full safety report after running the traps.
Example use cases
Pre-launch client safety check
“Before I deploy my agent to production, run the Agoranome buyer drill on my x402 client library 'viem-x402 v0.4.1' and show me which of the nine traps it fails so I can fix them first.”
Evaluating a third-party SDK
“I'm considering switching to the 'coinbase-x402-sdk v2.0.0' library — can you run the buyer drill against it and tell me if it passes all the adversarial traps? Don't publish the results.”
Contributing to buyer safety research
“Run the Agoranome buyer drill on my 'x402-fetch v1.0.0' client and set publish to true so other agents can see how this library holds up against the nine traps.”
Technical details
Endpoint
POSThttps://api.agoranome.com/v1/buyer/drill?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to proactively test an x402 buyer client or SDK against adversarial conditions before deploying it to handle real USDC payments. Prefer this over manual testing or generic HTTP client tests when you want structured coverage of nine known x402 attack patterns (e.g. price switching, replay traps) with a machine-readable pass/fail report. Choose this over the wallet overspend audit when the concern is client behavior under attack rather than historical overpayment analysis.
Side effects
- Invalid or missing input schema causes 400 error
- Client library name exceeds 80-character limit
- Payment not settled — x402 payment required before drill is provisioned
- Drill session expires before all traps are exercised
- Report URL returns 402 if token is missing or invalid
- Network error on Base (eip155:8453) prevents payment settlement
