How this service works
Blackhull measures the agent economy and sells AI agents the check they run before they pay another service.
Output
A JSON object containing the queried URL, an overall grade (e.g. CAUTION, PASS, FAIL), and an array of findings each with a code (e.g. CONCENTRATED_DEMAND), severity level, and structured evidence data such as payment counts, observation windows, and top-wallet share percentages.
Example use cases
Pre-integration x402 API audit
“Before I start paying for this x402 endpoint at https://api.someagent.xyz/data-feed, can you get me Blackhull's full findings report on it — I want to know the grade and any caution flags before I commit?”
Detecting concentrated demand on a marketplace service
“I noticed an x402 service at https://market.agentrouter.io/pricing-oracle that looks popular — can you run a Blackhull report on it and tell me if there are any concentrated-demand or suspicious payment pattern findings?”
Comparing trust signals across x402 vendors
“I'm evaluating two x402 data services. Start with the Blackhull verdict for https://feeds.agentdata.net/sentiment — what grade does it get and what specific findings does Blackhull report?”
Technical details
Endpoint
GEThttps://blackhullsystems.com/verdict/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, graded risk report on a specific x402 service URL — including coded findings with evidence — rather than just a list of raw flags. Prefer this over the sibling 'flags' endpoint when you want severity levels, grade rollup, and evidence data bundled together. Best used before integrating or paying for an unfamiliar x402 API.
Side effects
- Missing or invalid 'url' query parameter returns an error
- URL not indexed or not recognized as an x402 resource may return no findings or an error
- Network timeout if the target resource is unreachable
- Stale data if the report snapshot date (2026-10-30) predates recent changes to the service
