The data explorer's query (the page /explore): the open layer of every product we drove (CC BY 4.0), filtered: each product's level, where our agent stopped (the first checkpoint it didn't pass on its own) with the stop's one evidence line and links, its date and method release, its derived tags, and the bot checks it met; with the set's levels and checkpoint funnel ("n of N", a share only from 10 products), the coverage line and the source. Filters combine; area, category, level and tag repeat (any area, category or level; every tag). format=csv: the same rows as CSV (also GET /api/explore.csv). Observation-level history is licensed: layer=history answers 403 licence_required. 300 requests per 10 minutes per IP; cached 60 seconds

An area of the category tree (GET /api/explore/options areas), e.g. sales; other: a category in no area yet

A category slug, e.g. crm

A capability id of the shared vocabulary (GET /api/capabilities): products with a task of it; each row then carries capability_state

With capability: only products where our agent's work on it ended so

A derived tag (mcp, openapi, llms-txt, cli, webhooks, x402, mpp, free-plan, no-card-trial, card-trial): products with every tag given

Where our agent stopped, as the product page says (else the first checkpoint it didn't pass on its own); none: it passed every one

With outcome: the state of this checkpoint

With checkpoint: passed (on its own), help (a person did it), stopped, na (nothing to do), unreached (behind a wall), untried

A bot-check vendor our signed agent met (GET /api/explore/options vendors), e.g. cloudflare

With vendor: it stopped our agent, or let it in

Driven on or after

Driven on or before

A method release id (kb/rules/method-releases.json), e.g. 2026-Q4.3

Default: desc for level and date, asc for the rest

Only the open layer is public
