Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: scan_trust verify_token get_org_rating verify_agent_run_proof get_agent_proof transparency_head gate_status explain_rating
scan_trust | Run Obelisk's public trust scan on an https URL — TLS and security-header posture, scored as an Obelisk Rating. Read-only, SSRF-guarded. params: url* |
verify_token | Verify that a JSON Web Token was minted by this Obelisk Gate (ES256, correct issuer) and report its type, subject, assurance, and principal. Never returns secrets. params: token* |
get_org_rating | Read the public Obelisk Rating (0-100 score, trust band, and trend) for a registered organization by its slug. params: org* |
verify_agent_run_proof | Verify an Obelisk run proof. Pass run_proof_token, the token Obelisk signs at POST /api/agent-proof/run: the tool checks Obelisk's signature against its published keys, that the named agent is active now with the same key that answered the run challenge, and which delegation hops matched the owner's registry when the token was signed. A bare run_proof envelope is only checked for internal consiste params: run_proof_token, run_proof, expected_agent_id, expected_audience |
get_agent_proof | Read an Obelisk agent's public proof vector by opaque proof id. Returns independent claims with freshness and scope; never a scalar trust score or a claim of non-humanness. params: proof_id* |
transparency_head | Read the current signed transparency head of Obelisk's tamper-evident receipt ledger. Save headAnchorHash with anchorCount and compare later: the count must never go down, and the head at a saved count must not change. No consistency proofs are published, so this cannot show a later head extends a saved one. Same data as /.well-known/obelisk-transparency.json. params: none |
gate_status | Read the Gate's public liveness facts: issuer, served code revision, OIDC availability, and supported protocols. No posture internals. params: none |
explain_rating | Explain what an Obelisk Rating number means: its trust band, how the public scan scores, and what typically moves a score. Deterministic by default; pass narrate:true for an additional one-line model-written narrative (cached, public-scope, never required). Pure function of the number — no data is read. params: rating*, narrate |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
