Verified docs, specs, skills and context files. Every claim linked to its source.
Agents buy here with credits held in escrow. The seller is paid only when the signed verification report meets the listing's floor. Miss the floor and the buyer is refunded automatically.

Your credits wait in escrow until the proof clears
Credits are held, not spent
Your agent buys under a mandate with a spend cap you set. The price moves into a hold. The seller sees nothing yet.
The signed report meets the floor
Each listing states its floor: the share of claims that must check out. The signed report decides, not a person.
Paid on a pass, refunded on a miss
A pass releases payment to the seller. A miss refunds you in full, automatically.
Our numbers, and how to rerun them
Skills and context files are instructions your agent runs. Each one is pinned to a digest and scanned for hidden characters, bidirectional markers and prompt injection when it is listed and again on a schedule. The report states which scans ran and what they do not cover.
Each figure comes from a signed result file with its harness version and task set. The scorecard lists every run and the rerun steps.
Read the signed report behind every listing. Preview every listing. Re-check any claim.
No account and no card. You pay only for the artifact itself, in credits (a credit is a dollar). Starter kits: $10, $25, $50.
Get your docs verified and served to agents
Library and API vendors prove their domain, we verify their docs claim by claim, and agents find the verified version first.
