This record is unclaimed

Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.

Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"realworldapis","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Tools observed via MCP handshake

find_api_for_task — Find the best APIs for a natural-language physical-world task. Use this for open-ended task or outcome-based recommendations; use search_apis when you already k
search_apis — Search the canonical registry when you already know keywords or exact requirements. All supplied filter groups combine with AND logic; array capability filters
search_capabilities — Search the canonical 770-capability Verified/High decision graph directly. Use this when the question is about what an agent can actually do and under what exec
verify_requirement — Verify whether one specific API can satisfy one exact requirement using the canonical Verified/High capability graph plus linked assertion evidence. Returns YES
get_api — Retrieve one canonical API decision profile when you already know its name or slug. The response includes the full Verified/High capability profile with executi
compare_apis — Compare 2–8 already-known APIs side by side using canonical catalog fields plus capability-graph summary fields such as verified capability count, physical cons
