- freshness: 65

## Quality 93/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 4 of 9 tools declare all four hints; missing: get_vhh_index (destructiveHint, idempotentHint); get_balance (destructiveHint, idempotentHint); check_credential (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 1,613 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 9, about 1,613 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.LumiRx/5arz-proof-of-human.svg)](https://protogrid.dev/servers/io.github.LumiRx/5arz-proof-of-human)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (9)

- `check_credential`: Independently verify a 5arz PoHF JWT: checks the ES256 signature against the live public JWKS and validates expiry/not-before, then returns valid/invalid plus the decoded claims. No API key needed — this is pure cryptographic verification you could also do with any standard JWT library.
- `get_attestation_receipt`: Fetch a Proof-of-Human-Fulfillment receipt by attestation id. Returns the signed packet, verifier identifier, JWKS URL, and a how-to-verify hint. Free, no API key — pair it with check_credential to verify the signature yourself.
- `get_balance`: Return the current plan, seals and document checks used this month, and what remains. Requires an API key.
- `get_vhh_index`: Return the current Verified-Human-Hour (VHH) index — the benchmark price of one hour of verified human work/attention, in USD. Free, no API key. Useful for pricing verified-human data and as a citable benchmark.
- `list_verified_human_tasks`: List currently-buyable verified human work tasks. Each task includes its USD price, remaining slots, supported settlement chains, and the kind of Proof-of-Human-Fulfillment receipt issued on completion. Free, no API key.
- `purchase_verified_human_task`: Buy one slot of a verified human task. Called without payment it returns an HTTP 402 / x402 challenge with settlement instructions; settle USDC on the offered chain and call again with x_payment and purchase_id to receive an attestation_id — a verifiable Proof-of-Human-Fulfillment receipt. No API key required; the payment is the authentication.
- `register_agent`: Create a 5arz API key so your agent can request proof-of-human credentials. Every new key starts on the Free plan — 1,000 credential seals a month and 10 document checks, no card. Pass mode:"test" for an unlimited free sandbox key (arz_test_…) whose credentials are marked test:true — never treat test credentials as production proof. The key is shown once; store it.
- `subscribe`: Get a Stripe checkout link for a 5arz plan. Free (1,000 seals/mo, 10 document checks), Starter ($99/mo, 100k seals, $1.25/document check), Growth ($499/mo, 1M seals, $0.75/check), Scale ($2,499/mo, unlimited seals, $0.50/check). SEALS are credential signatures and are effectively free; DOCUMENT CHECKS are the vendor identity verification and are what you are really paying for. Human verification is always free to the human, at any volume. Requires an API key.
- `verify_human`: Mint a signed Proof-of-Human-Fulfillment (PoHF) credential attesting a real, ID-verified, live human performed an action. Provide sessionId to attest work fulfillment, or memberId to attest that an ID-verified human is behind an account (optionally wallet-bound). This does not establish that the person holds only one account — read sybil_checked in the returned claims before gating one-per-person actions. Counts as one seal against your monthly plan allowance (1,000/month on Free; unlimited for test keys). Returns an ES256 JWT that anyone can verify against the public JWKS — pass it to check_credential. Requires an API key (Authorization: Bearer, or the apiKey argument).
