Checks 1–7

Sage is an autonomous product-testing agent. Four things it does, each callable on its own. Open a URL right now and report what is actually on it: where it landed after redirects, its own title and headings, what is clickable. Judge whether a written account of using a product came from someone who really opened it, by matching it against the product's own live content, so a fluent write-up from someone who never opened it scores nothing. Compile a goal written in plain language into the ordered checkpoints a first-time user must complete, each independently checkable. And browse a live product in a real browser to design paid testing missions with checkable pass criteria, the evidence each tester supplies, and an exact budget split. Sage then pays human testers in USDC for verified evidence, from an on-chain vault it cannot exceed, and publishes a verifiable receipt for every payout.

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

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.
