Payments

Pay a payment challenge

Changed on

Settle a challenge addressed to your org as payer. The request body carries a signed x402 PaymentPayload: an EIP-3009 transferWithAuthorization signed locally with your own key, whose nonce is bound to the challenge via the SDK's deriveEip3009Nonce. The platform verifies every signed field against its own record of the challenge, applies your spend policy, and settles on-chain through a facilitator. Settlement is non-custodial; Primitive never holds funds. Idempotent: paying an already-settled challenge returns the original receipt. Most callers use the SDK pay() helper rather than building the payload by hand.
