Best When

You need reliable Ethereum RPC access and IPFS in one provider, especially for MetaMask-ecosystem or ConsenSys-adjacent projects.

Avoid When

You need enhanced beyond-RPC APIs like NFT metadata, token balances across wallets, or webhook notifications.

Use Cases

• Ethereum node access without running your own node
• Reading blockchain state: balances, transactions, smart contract data
• IPFS file storage and retrieval for decentralized apps
• Broadcasting signed transactions to the Ethereum network
• Querying historical transaction data and event logs

Not For

• Enhanced blockchain APIs beyond raw JSON-RPC (use Alchemy for NFT/Token APIs)
• Applications requiring real-time event streaming with complex filters
• Chains outside Infura's supported network list

Pricing

Model: freemium

Free tier: Yes

Requires CC: No

Free tier has daily request limit. Rate limits apply per second on all tiers. IPFS storage and retrieval have separate quotas.

Known Gotchas

⚠ Daily request quota resets at midnight UTC - agents with predictable patterns may hit limit at end of day
⚠ eth_getLogs calls without blockhash range are limited to 10,000 results - agents must paginate log queries
⚠ IPFS gateway is separate from Ethereum RPC - different endpoint URL, different auth method
⚠ WebSocket support exists but reconnection must be handled by the client
⚠ Some advanced debug and trace methods are not available on free tier or require archive node add-on
