How payment works

x402 for agents

Call a /x402/v1/ route. An unpaid call returns HTTP 402 with the exact terms; an x402 client signs a USDC authorization and retries. A keyless facilitator (PayAI, or XPay as fallback) settles it on Base and the answer or download link comes back in the same response.

Plain transfer for files

Start an order to get an exact, order-specific amount. Send it from any wallet as one USDC transfer on Base and paste the transaction hash. The Worker checks the chain, token, recipient, amount, status, time and confirmations itself, then releases a signed link.

Never charged for nothing

School Signals queries are checked before any payment: unknown or ambiguous buyers, invalid filters and empty results are refused with no 402. Each transaction hash is accepted once.

Network	Base mainnet, chain id 8453
Token	USDC (Circle), contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`
Recipient	`0x491Fcf30a5aa0483B3cd8C0041d21801F195B3AF`
Not accepted	Other chains (including Solana), bridged USDbC, other tokens, card payments

Payment goes straight to the seller's own wallet. There is no merchant of record, card processor or platform in between, and payments on Base are irreversible. Buyers pay Base gas on plain transfers; on x402 the facilitator pays it. See how to verify a payment.
