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.

- Get a key at the provider
- 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.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
Developer reference
Free Core plan: 6,000,000 credits/day (a separate FAQ blurb states a 2,000 credits/second throughput cap, while the plan-comparison table states 500 credits/second -- both figures are live on infura.io/pricing and disagree, so both are cited rather than picked arbitrarily); Developer 4,000 credits/second, Team 40,000 credits/second.
