How this service works
Pay-per-call endpoints over x402 v2 and MPP (the "Payment" HTTP auth scheme, method usdc). Includes counterparty compliance checks: /report/counterparty (company + registered parents + UN/OFAC/EU/UK sanctions, signed and verifiable), /screen/name and /screen/entity. Free: /health, /.well-known/x402, /receipts, /prove/keys, /prove/stats.
Output
Returns a JSON object with: ok (true/false), type ('credits'), the header name for submitting credits (X-Genesis402-Credit), a receipt object with tx_hash, amount_usd, and receipt_id, a credit_id, a balance_url for checking remaining balance, the current balance in USD as a string, and a one-time-visible credit_token (g402c_ prefix, 43 chars) to authenticate future API calls.
Example use cases
Fund compliance screening budget
“I need to run a bunch of sanctions and OFAC checks on some counterparties today — top up my Genesis402 account with $5 USDC now so I have credits ready and save the credit token for me.”
Prepay for DeFi data API access
“Before I start pulling Cardano and Rootstock DeFi data from Genesis402 all afternoon, add $5 of USDC credits to my account and give me the balance URL so I can track usage.”
Provision agent with API credit token
“Set up my AI agent with Genesis402 API credits — buy a $5 USDC credit pack and store the credit token so the agent can start making pay-per-call requests on its own.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/credits/5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to pre-purchase a block of Genesis402 API credits (rather than paying per-call inline) and want a reusable credit token for subsequent calls, especially when orchestrating multiple downstream Genesis402/UnyKorn API calls (compliance screening, DeFi data, crypto prices) in a single session. Prefer per-call x402 payment if you only need one or two calls.
Side effects
- Payment not received or insufficient USDC — x402 payment challenge returned instead of credit token
- Invalid or malformed x402 payment header — 402 or 400 error
- Network or blockchain confirmation delay — timeout or pending state
- Duplicate payment detected — idempotency conflict
- Endpoint unavailable — 503 from operator network
