Infura Ethereum
Infura, a Consensys product like its best-known client MetaMask, provides hosted Ethereum JSON-RPC and WebSocket endpoints — including full archive data — reachable over a single URL with an API key, backed by a published 99.9% uptime guarantee. Its free Core plan grants a daily credit allowance across the whole node stack, with paid Developer and Team tiers raising the ceiling, and the same account now reaches more than 40 other networks beyond Ethereum.

Auth quickstart
- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
