How this service works
Should my agent pay these x402 endpoints? Up to 25 listings from nohumans.directory in one call: pay, caution or avoid for each, with plain reasons, including whether we bought it with real USDC and it delivered.
Output
A JSON object containing: a count of verdicts returned, an as-of Unix timestamp, a rule string explaining the verdict logic, an array of verdict objects (each with the listing ID, a pay/caution/avoid recommendation, and a plain-language reason including whether a real USDC purchase was made and delivered), and an array of IDs that were not found in the directory.
Example use cases
Pre-flight check before agent payment run
“I'm about to let my agent pay a batch of x402 APIs — can you check nohumans.directory verdicts for these 8 listing IDs first and tell me which ones are safe to pay, which need caution, and which to skip entirely: list001, list002, list003, list004, list005, list006, list007, list008?”
Vetting newly discovered paid data sources
“My agent just discovered 12 x402 endpoints on agentic.market. Before spending any USDC, pull the nohumans.directory verdicts for all 12 listing IDs — I want to know if any of them actually delivered when the directory bought them with real money.”
Auditing an existing agent's API allowlist
“We have 20 x402 API listings in our agent's approved payment list. Can you run a bulk verdict check on all 20 IDs against nohumans.directory to see if any have dropped to caution or avoid status since we last checked?”
Technical details
Endpoint
GEThttps://api.nohumans.directory/v1/verdicts?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs to evaluate multiple x402 API listings in a single call rather than checking them one by one — it is the most efficient pre-spend trust check for batch workflows. Prefer this over the single-listing verdict endpoint when you have 2–25 IDs to assess simultaneously. It is the right choice when you want real-purchase confirmation (not just probe data) for a set of paid APIs before committing USDC.
Side effects
- Missing or empty 'ids' query parameter returns an error — at least one listing ID is required
- More than 25 IDs submitted in a single call may be rejected or truncated
- Invalid or malformed listing IDs return those IDs in the 'not_listed' array rather than verdicts
- Stale data if the directory hasn't recently probed a listing — check the as_of timestamp
- HTTP 402 payment required if the $0.1 USDC x402 payment is not included in the request
- Network timeout if the directory is re-probing endpoints in real time
