	Description		Read-only	Idempotent	Open world
`bind_human_to_payment`Bind a verified human (a 5arz sessionId or memberId) to a payment you already made, on any rail, and get back a signed credential (atb_jwt) that cross-references the payment and is bound to your agent key. Does not move money. Requires an API key; uses one seal.

`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. Accepts either the legacy pohf_jwt / pop_jwt or the standards-conformant sd_jwt_vc (IETF SD-JWT VC, typ dc+sd-jwt).

`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.

`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.	Buy one slot of a verified human task.

`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.	Get a Stripe checkout link for a 5arz plan.

`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).
