Pass mode:"test" for an unlimited free sandbox key (arz_test_…) whose credentials are marked test:true — never treat tes
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 per
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 eith

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.

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).

Return the current plan, seals and document checks used this month, and what remains. Requires an API key.
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 write/delete
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 ke
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.
