How this service works
Calculate a SHA-256 digest and UTF-8 byte length of supplied text without normalization. Useful for comparing exact text artifacts. Does not prove authorship, authenticity or safe content; do not submit passwords or secrets.
Output
Returns a JSON object containing the SHA-256 hex digest of the input text, the encoding used (UTF-8), the algorithm name (SHA-256), the UTF-8 byte length of the input, and a note confirming no normalization was applied. Also includes a request ID and provenance metadata confirming the computation is deterministic and local with no model or network involvement.
Example use cases
Text artifact deduplication check
“Hash this paragraph for me so I can check if it's a duplicate of something I stored earlier: 'The quick brown fox jumps over the lazy dog.'”
Document integrity fingerprinting
“I need a SHA-256 digest of this contract clause — no normalization, keep line endings as-is — so I can verify it hasn't been tampered with later: 'Payment is due within 30 days of invoice.'”
Byte length measurement for encoding
“What's the UTF-8 byte length of this Japanese text: '日本語のテキスト'? Also give me its SHA-256 hash while you're at it.”
Technical details
Endpoint
POSThttps://www.tradepilotusa.com/api/agent-commerce/v1/services/text_sha256_digest/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, no-normalization SHA-256 hash of an exact text artifact — particularly when line endings and Unicode code points must be preserved exactly as-is. Prefer it over local hashing when you want a pay-per-use, auditable, externally verifiable computation without setting up local crypto libraries. Not suitable for password hashing, authentication, or content safety verification.
Side effects
- Text exceeds 48,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 protocol — endpoint returns 402 before processing
- Malformed JSON body — 400 bad request
