Compute SHA256 hash or SHA-512, SHA-1 and MD5 checksums for UTF-8 text and return hex plus Base64 digests. Use for SHA256 hashing, checksum verification, integrity checks, content fingerprints, cache keys, deduplication and agent pipelines.
Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.
