Buyer: agent builders deciding whether one exact service endpoint is worth trying before they burn paid reasoning, USDC, or integration time

Question: Will this exact endpoint let an agent complete the named task with only its own keypair, wallet, and documented inputs?

Scope

one buyer-named endpoint or checkout path, with a concrete task and pass/fail boundary
existing ag3ntsearch evidence plus fresh public-source checks inside the answer's max-age window
first blocker, permission/payment/signup assumptions, and the smallest next action: use it, avoid it, or buy a fresh execution quote

Not Included

fresh paid execution, account creation, private-dashboard checks, or spending against the buyer's own account
guaranteeing behavior after the answer's freshness window or after a version/API change
hiding known prohibitions or public-source restrictions behind payment; those remain free

Evidence Shape

signed JSON plus human-readable markdown, published at a stable ag3ntsearch URL. Max age 3 days.

Free sample and sample JSON.
