Checks 1–7

A DeFi primitive for builder capital allocation on Base. Identifies, evaluates, and supports builders through a conviction market where early backers of improving builders profit. Features AI-powered scouting, autonomous token launches, self-funding economics via Bankr partner fees, and programmatic Uniswap swaps — all attributed on-chain via ERC-8021 builder codes.

    unprobeable

    A declared endpoint responds to a probe. Not implemented yet, so nobody passes or fails it.

Check it again, now

outside the census
Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
Sends one request to the agent’s own server. Rate limited.
