Credentials
Quicknode API key (QN_*)api_keyGet key ↗

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.

x402 wallet-based payment/authsignatureGet key ↗

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 credentialsignatureGet key ↗

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 account OAuth authorizationoauth2Set up OAuth ↗

Create a Quicknode account at Sign up, then connect from an MCP client such as Claude, ChatGPT, Codex, Cursor, or VS Code as described in Quicknode MCP. On first connection, the MCP client opens a browser to log in to Quicknode and approve access.
