What is Infura?
Infura is a blockchain node and API service run by Consensys that gives developers RPC access to 40+ networks. The free Core plan includes 3 million credits per day; paid plans start at $50 per month.
How Infura works
Infura charges each request against a daily credit quota according to the method's weight.
In its credit table, eth_blockNumber, eth_call and eth_sendRawTransaction cost 80 credits, eth_getLogs 255 and eth_blobBaseFee 300. In a batch, every inner call and the batch itself consume credits. WebSocket subscribe and unsubscribe calls, and each event received, also draw on the quota, and the connection is cut once the daily limit is reached. Archive reads older than 128 blocks currently cost the same as recent ones.
Infura never holds your private keys, so eth_sendTransaction, eth_sign and eth_coinbase are unsupported on every network. You sign locally and submit with eth_sendRawTransaction. On Arbitrum, Avalanche C-Chain, Optimism and Polygon, customers on Growth or Custom plans can add a failover header so that requests are forwarded to a partner provider if Infura has an outage.
How to start with Infura
- Register on the Infura dashboard and confirm your email.
- Infura then creates a key called My First Key with every network endpoint enabled, and you send POST requests to URLs such as https://mainnet.infura.io/v3/ followed by the key.
- The free plan allows one API key, Developer allows five and Team has no limit.
- Request visibility in the dashboard covers 24 hours on the free plan and 30 days on paid plans.
Infura fees and limits
- Developer costs $50 per month for 15 million daily credits at 4,000 per second and adds Debug and Trace APIs.
- Team costs $225 per month for 75 million daily credits at 40,000 per second.
- A $200 monthly add-on buys 55 million additional credits, and crypto payment is limited to custom plans.
Core is free with 3 million credits per day at 500 credits per second. Upgrades take effect immediately and downgrades apply at the end of the billing cycle. One caveat: the FAQ on the pricing page still describes the free plan as 6 million credits per day at 2,000 per second, which conflicts with the plan table and the pricing docs, both of which say 3 million and 500.
Risks to know before using Infura
- When you exceed the daily quota, Infura sends notifications and may rate-limit you, and open WebSocket streams are cut once the daily limit is reached.
- Failover protection is limited to four networks and to Growth or Custom plans, which Infura has since folded into Enterprise.
- The IPFS API and dedicated gateway are open only to pre-qualified customers who apply through support.
