What is checked

The signer is recovered from the signature over keccak256(requestHash, timestamp, data) and compared with the Airnode addresses published in each API's spec on AirnodeHub. When the request is included, its hash is recomputed from the operation and parameters, so a valid answer cannot be passed off as the answer to a different question.
