47620 Utilities API – SHA-256 Fingerprint
x402
47620 Utilities API – SHA-256 Fingerprint is a paid API for AI agents from 47620.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).
Computes a SHA-256 fingerprint of any input string, returning the full hex digest, colon-separated SSH-style fingerprint, a 16-char short ID, and base64 encoding.

How this service works
Compute a SHA-256 fingerprint of any string: full hex digest, colon-separated (like SSH fingerprints), a short 16-char id, and base64. Deterministic, CPU-only. Pass ?text=<content>.
Output
Returns a JSON object containing the SHA-256 hash of the input string in four formats: full lowercase hex digest, colon-separated pairs (SSH fingerprint style), a 16-character short identifier, and standard base64 encoding. The computation is deterministic and CPU-only with no external dependencies.
Example use cases
Deduplication key for content pipeline
“Generate a SHA-256 fingerprint for this article text so I can use it as a deduplication key — give me the short 16-char ID and the full hex digest: 'The quick brown fox jumps over the lazy dog.'”
SSH-style fingerprint for an API key
“Take this API key string 'sk-abc123xyz789' and give me its SHA-256 fingerprint in colon-separated SSH format so I can log it safely without storing the raw key.”
Base64 hash for a data integrity check
“Compute the SHA-256 hash of the string 'user:alice@example.com:2024-06-01' and return it as base64 so I can embed it in a webhook signature header.”
Technical details
Endpoint
GEThttps://47620.xyz/x/util/fingerprint?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need SHA-256 fingerprints in multiple output formats simultaneously (hex, colon-separated, short ID, base64) from a single API call, without needing to implement hashing locally. Particularly useful in agentic workflows where you need deterministic, reproducible content identifiers, deduplication keys, or SSH-style fingerprints without deploying compute infrastructure.
Side effects
- Missing or empty `text` query parameter — may return an error or hash of empty string
- Input string too large — may trigger payload size limits
- Network timeout on slow connections despite fast CPU computation
- Payment failure via x402 protocol preventing endpoint access
