How this service works
VERIFY QuickCheck — agent transaction intelligence. Before your agent pays an unknown x402/MCP resource: identity history, wallet stability, price percentile vs the observed market, change events, live protocol probe, risk verdict (ALLOW/REVIEW/DENY). Built on daily longitudinal snapshots of the entire x402 Bazaar.
Output
Returns a structured risk assessment including: the resource's identity and ownership history, wallet stability metrics, how the listed price compares to the observed market (price percentile), any recent change events (URL, price, or operator changes), results from a live protocol probe of the endpoint, and a final risk verdict of ALLOW, REVIEW, or DENY to guide the agent's payment decision.
Example use cases
Example prompt
“Before you pay for that x402 resource at https://api.example.com/data, run a VERIFY QuickCheck on it so I know if it's ALLOW, REVIEW, or DENY — I want to see the price percentile and whether the wallet has a stable history.”
Technical details
Endpoint
POSThttps://verify.inferenceview.com/check?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent is about to make a payment to an unknown or unverified x402/MCP resource and needs a pre-payment risk check. It is specifically designed for the x402 ecosystem and draws on longitudinal daily snapshots of the x402 Bazaar, making it more accurate than generic URL scanners or reputation services that lack x402-specific market and wallet data. Prefer it over generic fraud detection APIs when the resource is a paid x402 endpoint.
Side effects
- URL not found in x402 Bazaar history — returns limited or no longitudinal data
- Invalid or non-x402 URL provided — returns validation error
- Endpoint unreachable during live probe — probe result marked as failed
- New resource with no snapshot history — verdict may default to REVIEW due to insufficient data
- Rate limiting or payment failure — call rejected if USDC payment is not processed
