Verify output and validate work another AI agent hands back, before you pay, rel
Verify output and validate work another AI agent hands back, before you pay, release escrow, or pass it on. An acceptance test and quality check: send the task and the deliverable, get accept or reject with every requirement judged. Counts, required JSON fields, and sums are checked in code. Deliverables that certify themselves or inject instructions never pass. Signed receipt binding task, deliverable, and payment hashes. $0.03.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
