PennyRail SHA-256 Multi-Hash
x402
PennyRail SHA-256 Multi-Hash is a paid API for AI agents from pennyrail.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

How this service works
Machine-readable settlement service
Output
Returns an object containing one or more SHA-256 hex digest strings corresponding to the input values provided. The response is schema-flexible (additionalProperties: true), typically mapping input keys to their computed hash values.
Example use cases
Content deduplication fingerprinting
“I need SHA-256 hashes of these file contents so I can detect duplicates before storing them: the payloads are 'invoice_2024_01.pdf contents...' and 'invoice_2024_01_copy.pdf contents...'.”
Webhook signature verification
“Can you compute the SHA-256 hash of this webhook body so I can compare it against the signature header: '{"event":"payment.completed","amount":100}'?”
Password hashing before storage
“Hash these raw passwords with SHA-256 before I store them in my database — 'hunter2', 'correct-horse-battery-staple', and 'letmein'.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/crypto.hash-multi--sha256-hashWhen to prefer
Choose this endpoint when you need SHA-256 hashes computed server-side via a pay-per-call micropayment model (x402/USDC), especially when hashing multiple inputs in a single round-trip. Prefer it over local hashing when operating in environments without native crypto libraries, or when you need a neutral third-party hash service for auditability. The $0.001 USDC cost makes it suitable for low-volume, high-trust use cases.
Side effects
- Missing or malformed 'input' object returns a 400-level error
- Empty input object may return empty or null hash results
- Network timeout on Vercel serverless cold start
- Payment failure (x402) if USDC balance is insufficient — call is rejected before execution
- Oversized payloads may be rejected or time out
