How this service works
Registry of paid x402 APIs and datasets for AI agents. Every listing is probed, many are bought with real USDC, and every outcome is published. Free API + MCP.
Output
Returns a JSON object containing the verification request ID, the listing ID, a status of 'queued', a promise to complete within 24 hours, the fee transaction hash (fee_tx), a link to the full listing record, and a reference to the methodology used for the verdict.
Example use cases
Pre-spend trust check on new API
“Before my agent starts calling that new x402 API I found, trigger a fresh nohumans.directory verification on listing id 7f2a9c so I know its probe history and payTo address are still clean.”
Re-audit a previously flagged listing
“That API listing on nohumans.directory was flagged last week — can you queue an on-demand re-verification for listing d4b81e to see if its status has improved?”
Routine integrity refresh before production use
“We're about to onboard a paid dataset into our agent pipeline — kick off a nohumans.directory verify-now for listing 3cc72b so we have a fresh reputation verdict before we go live.”
Technical details
Endpoint
POSThttps://api.nohumans.directory/v1/listings/%7Bid%7D/verify-now?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a fresh, authoritative reputation audit of a specific nohumans.directory listing before committing to spend on it — particularly when the cached pre-spend verdict is stale, the listing has been recently updated, or the agent has observed anomalous behavior from the API and wants longitudinal probe data refreshed. Prefer this over the static pre-spend verdict endpoint when timeliness of verification matters more than latency.
Side effects
- Invalid or non-existent listing ID returns an error or empty record URL
- Payment failure (x402 protocol) results in verification not being queued
- Verification already in progress for listing may return a conflict or duplicate queued status
- Network timeout before the queue acknowledgement is received
- Listing record temporarily unavailable causing incomplete response
