Which x402 endpoints actually settle: counts from the latest measurement cycle, where every data point is a real purchase we paid for. Catalogs list who exists; this reports who charged

Only what changed since your last call: pass the cursor you got back and receive just the new whale events, never the whole base again. Built for agents that poll on a schedule and pay per request

Real-time prompt injection firewall and jailbreak detector for autonomous agents. Inspects untrusted input (scraped web pages, social feeds, user messages) and returns a machine-readable security verdict: safe flag, 0-100 risk score, threat

Prepaid API credits and API key for clients that cannot sign an x402 payment per call (most MCP clients): one payment buys credit ($5, $20 = $22 credit, $50 = $60) and returns an API key. Send it as X-API-Key on any paid route or MCP tool; each call costs its x402 price and failed calls are refunded. With your key in X-API-Key it tops that key up.

Call before paying an unfamiliar x402 endpoint. Sends an unpaid request and validates its 402, compares price and payTo with its Bazaar listing (catches hijacked payTo), and scores 30-day demand for fake-traffic patterns. Returns TRUSTED / OK / SUSPECT / AVOID.

GPT-5.6 Luna — fast, low-cost frontier model (Artificial Analysis Intelligence Index 51.2, GPQA Diamond 91.1%).

OpenAI-compatible request and response format.

Return a low-cost deterministic paid receipt proving the AUN x402 purchase path delivered its contracted response; intended for autonomous service/liveness verification, not downstream business-value proof.

x402 Endpoint Payment Check. Check an x402 endpoint's 402 payment-required body before you rely on it. Reports whether the contract is payable, whether it is opted in to the Bazaar catalogue, and whether a buying agent can read its input schema by machine. Every defect carries a JSON evidence path. Reads the body you supply; it does not pay or call the endpoint. A PASS is not a correctness guarantee and not a claim that the service is accurate.
