RelayStation Hash Utility
x402
RelayStation Hash Utility is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Hashes arbitrary bytes using SHA-256, SHA-512, SHA-1, or MD5 and returns the digest as a hex string, billed per megabyte of input.

How this service works
$0.0002/MB. Hash bytes with SHA-256, SHA-512, SHA-1, or MD5 — digests as hex. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
Returns the hex-encoded digest of the input bytes using the chosen algorithm (SHA-256, SHA-512, SHA-1, or MD5). The response contains the hash string ready to use for integrity checks, deduplication, or signing workflows. Billing is $0.0002 per MB of input, with a 1¢ minimum charged via x402; any remainder is auto-credited.
Example use cases
File integrity checksum before upload
“Before I upload this document, compute its SHA-256 hex digest so I can store it for integrity verification later — here's the content: 'Invoice #1042: $5,000 due 2024-06-01'.”
Deduplication fingerprint for stored content
“I need to deduplicate my article cache — can you generate an MD5 hex hash of this article body so I can check if I've already stored it? The text is: 'The quick brown fox jumps over the lazy dog, again and again.'”
Data signing preparation with SHA-512
“Hash this JSON payload using SHA-512 and return the hex digest so I can include it in my audit log: '{"user":"alice","action":"delete","timestamp":"2024-05-15T10:00:00Z"}'.”

Endpoint
POSThttps://api.relaystation.ai/v1/utils/hashWhen to prefer
Choose this endpoint when you need a fast, pay-per-use cryptographic hash over HTTP without managing your own hashing infrastructure. It is especially useful in agentic workflows where a step requires a checksum, fingerprint, or integrity digest and spinning up local compute is impractical. It supports four common algorithms (SHA-256, SHA-512, SHA-1, MD5), making it flexible for legacy compatibility (MD5/SHA-1) or modern security needs (SHA-256/SHA-512). Prefer it over local computation when the agent runtime lacks native crypto libraries or when the hash must be performed server-side for audit reasons.
Side effects
- Unsupported algorithm specified — endpoint accepts only SHA-256, SHA-512, SHA-1, MD5
- Empty or missing input body — returns error indicating no data to hash
- Malformed request payload — missing required algorithm or data fields
- Payment failure via x402 — insufficient USDC balance or wallet not configured
- Input data too large — may hit size or timeout limits for extremely large payloads
