One Starkscan key powers RPC, REST, SDK, CLI, and MCP. Use it for the RPC node URL or JSON-RPC header auth. REST core routes are certified, authenticated RPC and hosted MCP remain beta surfaces, and SDK, CLI, and MCP packages install from the stable npm channel.
GitHub sign-in opens your API key settings. Create keys there and copy each secret once.
For software that only accepts a node URL, use /rpc/v0_10/{chain}/<key>. For servers, use https://api.starkscan.co/v1/{chain}/rpc with X-Starkscan-Api-Key. Keep full keys and URL-token forms in a secret store.
By continuing, you agree to the Starkscan Terms of Use and acknowledge the Privacy Policy.
