flat-rate-llm.kikoribera03.workers.dev · 74 paid endpoints · listed 2026-10-27
Use when an agent must prove two payloads are the same byte for byte, or sign an API request: SHA-256 of any string or hex payload, returned as hex and as base64, which are the two forms signatures and content addresses are written in. Do not use for anything Ethereum hashes: the chain uses Keccak-256 (/v1/util/keccak256), which gives a different digest. No API key, no account.
