← All APIs dRPC is a decentralised RPC network over 100+ chains. This Airnode wraps both halves worth attesting: the standard Ethereum JSON-RPC reads of chain state on any EVM chain dRPC serves, one operation per method, and the indexed Data API for wallets, tokens, NFTs and DeFi.
Every response carries an EIP-191 signature from the Airnode that served it, so the data can be attributed back to its source rather than trusted on reputation.
Ask the Hub what dRPC can tell you → Interface Served at https://airnode-drpc.fly.dev/. Each operation is reached the way the provider documents it, under https://airnode-drpc.fly.dev/api, and answers with the provider's own response and the attestation in headers, so a client built against the provider works unchanged. The same operations are also served as one JSON envelope on POST /, which the HTTP interface covers. Every request below can be sent from this page, and what comes back is verified right here in the browser.
GET / Returns the machine-readable documentation this page is rendered from. Free, and everything an agent needs.
ANY /api/… The provider's own requests, one per operation, forwarded as they are. The provider's response comes back untouched, with the attestation in the X-Airnode headers.

Free POST /api/ogrpc eth_getBlockByNumber One block by number, with its transaction hashes or whole transactions. Null for a block the chain has not reached. Free POST /api/ogrpc eth_getBlockByHash One block by hash, with its transaction hashes or whole transactions. Null when the chain has no such block. Free POST /api/ogrpc eth_getBlockReceipts Every transaction receipt in one block. A block the chain has not reached is refused.

Free POST /api/ogrpc eth_createAccessList The addresses and storage slots a transaction would touch, and the gas it would use with that access list. Free POST /api/ogrpc eth_simulateV1 Simulate a sequence of calls over one or more blocks built on a given block, and return each simulated block with its calls' results. Free POST /api/ogrpc eth_getLogs The event logs matching a filter, over a block range or in one block. Too many matches come back under error, and an answer past 50 MB fails.
