Superhighway Hash — Text Hashing Utility
x402
Superhighway Hash — Text Hashing Utility is a paid API for AI agents from superhighway.walls.sh, paid per call via x402, $0.001/call, status down (last checked 2026-09-15).
Computes a cryptographic hash (MD5, SHA-1, SHA-256, SHA-384, or SHA-512) of a given text string, returning the result in hex, base64, or base64url encoding.

How this service works
Web search built for AI agents. Search the live web, pull recent news, and read any page as clean markdown — pay per call, free tier to start.
Output
Returns the cryptographic hash of the input text as a string in the requested encoding (hex, base64, or base64url), computed using the specified algorithm (SHA-256 by default).
Example use cases
Example prompt
“Hash the text 'hello world' using SHA-256 and give me the result in base64 encoding.”
Technical details
Endpoint
GEThttps://superhighway.walls.sh/hashWhen to prefer
Use this endpoint when you need a quick, pay-per-call cryptographic hash of a text string without setting up a local hashing library, or when operating in an environment where calling an external API is more convenient. Good for lightweight integrity checks, token generation, or producing deterministic identifiers from text.
Side effects
- Missing required 'text' parameter returns an error
- Invalid algorithm name not in [md5, sha1, sha256, sha384, sha512] may return an error or default
- Invalid encoding value not in [hex, base64, base64url] may return an error or default
- Empty string input may return a valid hash of empty content
- Payment failure (x402) if USDC balance is insufficient
