How this service works
Machine-readable settlement service
Output
An object containing hash digests of the input computed across multiple cryptographic algorithms (e.g., SHA-256, MD5, SHA-1, SHA-512). Each key in the response corresponds to a hash algorithm name and its value is the resulting hex or base64-encoded digest string.
Example use cases
Content deduplication fingerprinting
“Hash this file metadata object across multiple algorithms so I can use it as a deduplication key in my storage system: {"filename": "report_q2.pdf", "size": 204800, "owner": "alice"}.”
Data integrity verification before signing
“Give me the multi-algorithm cryptographic hashes of this transaction payload before I sign it, so I can verify integrity later: {"to": "0xABC", "amount": "100", "nonce": 42}.”
Content-addressed identifier generation
“I need to generate a deterministic multi-hash fingerprint for this JSON object to use as a content-addressed ID in my distributed system: {"type": "event", "data": "user_signup", "userId": "u_9912"}.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/crypto.hash-multi--hashWhen to prefer
Choose this endpoint when you need to compute cryptographic hashes across multiple algorithms in a single network round-trip rather than calling separate hash endpoints. It is well-suited for content addressing, deduplication, integrity verification, and scenarios where deterministic multi-algorithm fingerprints are required. Prefer it over single-algorithm hash services when you need hash agility or want to future-proof your hashing strategy.
Side effects
- Missing or malformed 'input' field returns a validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Empty input object may produce zero-length or undefined hash results
- Network timeout on the Vercel serverless function under heavy load
- Unsupported input types (e.g., binary blobs passed as raw JSON) may cause serialization errors
