Open data
Three datasets, free, CC-BY-4.0
Everything Sato Hub publishes about the onchain agent stack, in the formats a program wants. No key, no signup. Attribution: data by satohub.ai. Scores and liveness are informational signals, not safety or quality guarantees. The catalog fields are free; score history, provenance and trust components live on the site and behind the MCP server.

374 listings — the directory itself, catalog fields only.

- /api/resolve?repo=… / ?package=… — a GitHub URL or npm name to its listing, score and verify page.
- /api/badge/<slug> (SVG) and /api/badge/<slug>.json (shields endpoint) — see badges.

- github.com/satohubai/onchain-agents — the index rendered daily as a repository, with weekly tagged releases and a CITATION.cff.
