How this service works
Validate exact UTF-8 SHA-256 hashes for up to 64 public or synthetic passages. No Unicode normalization, source authentication, or semantic validation. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
Output
Returns hash validation results indicating whether each supplied SHA-256 hash is an exact UTF-8 match for its passage, along with minimal receipt metadata retained for 90 days and full results retained for 24 hours.
Example use cases
Audit harvested research excerpts
“I have 20 excerpts I scraped from public sources and computed SHA-256 hashes for each — can you validate that all the hashes are exactly correct for these public passages?”
Verify synthetic dataset fingerprints
“We generated a batch of 50 synthetic text passages and assigned each a SHA-256 hash — please check that every hash is an exact UTF-8 match with no normalization so we can certify the dataset.”
Integrity check before evidence submission
“Before I submit these 10 passage hashes as evidence, can you run a validation to confirm every SHA-256 hash is an exact match for the corresponding public passage text?”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/verify/evidence/passage-hashes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need strict, exact UTF-8 SHA-256 hash verification for up to 64 text passages — specifically when Unicode normalization must NOT be applied and you need a fast, low-cost integrity check for public or synthetic passage data. Prefer this over general-purpose hash utilities when you require receipt metadata and result retention with a clear audit trail.
Side effects
- Invalid or malformed SHA-256 hash format returns a validation error
- Passages array exceeds 64 items triggers a schema validation rejection
- Unsupported dataClass value (not 'public' or 'synthetic') causes request failure
- Empty passages array rejected due to minItems constraint
- Results expired after 24-hour retention window returns a not-found error
