Authentication

x402 wallet-based payment/auth signature discovered Get key ↗

PAYMENT-SIGNATURE: <credential>

Use a funded wallet and the x402 flow described in x402 Payments. Quicknode documents that agents sign a SIWE/SIWX message, receive a JWT, and pay by attaching the x402 payment header on each request; the easiest path is to use the `@quicknode/x402` SDK.

MPP wallet-based payment credential signature discovered Get key ↗

Authorization: Payment <credential>

Use the Machine Payments Protocol flow from MPP Payments. Quicknode recommends the mppx client so requests automatically handle the HTTP 402 payment challenge and send Authorization: Payment ... credentials to https://mpp.quicknode.com.

Quicknode API key (QN_*) api_key discovered Get key ↗

x-api-key: <credential> /Authorization: Bearer <credential>

Create a Quicknode account at Sign up, then generate or manage an API key in the Quicknode dashboard API Keys page. Agents can also obtain a one-time QN_* key programmatically via the Agent Subscription API guide.
