How this service works
nohumans.directory pre-spend verdict for one listing: probe history, payTo age and stability, paid-delivery outcome, verified verb, and a pay/caution/avoid verdict with reasons.
Output
Returns a JSON object with a 'verdict' field ('pay', 'caution', or 'avoid'), a 'status' string, a 'listing_id', an optional 'verified_via' field indicating verification method, and a 'reasons' array explaining the recommendation based on probe history, payTo address age and stability, and paid-delivery outcomes.
Example use cases
Pre-spend check before API call
“I'm about to pay $0.01 to call listing xyz789 on nohumans.directory — can you pull the verdict first and tell me if it says pay, caution, or avoid?”
Automated agent trust gate
“Before my agent spends any money on listing def456, get its nohumans.directory verdict and only proceed if the verdict is 'pay' — otherwise show me the reasons to avoid it.”
Evaluating a new data API source
“I found a paid API listing with ID ghi321 that claims to deliver stock data — can you check the nohumans.directory verdict to see how it scores on probe history and paid-delivery reliability?”
Technical details
Endpoint
GEThttps://api.nohumans.directory/v1/listings/:id/verdictWhen to prefer
Use this endpoint when an AI agent is about to make a paid x402 API call and needs a pre-spend trust signal to decide whether to proceed. It is specifically designed for agentic workflows that need automated go/no-go decisions on paid API listings in the nohumans.directory ecosystem, based on empirical probe history rather than self-reported metadata.
Side effects
- Listing ID not found — returns error if the provided ID does not correspond to a known listing
- Insufficient probe history — verdict may return 'caution' with limited data
- Stale or unverified listing — verified_via may be null if automated verification has not completed
- Network timeout — fast endpoint but may fail transiently under load
- Invalid ID format — malformed listing ID causes bad request error
