How this service works
Keyless pay-per-call APIs for AI agents on Base: token risk verdict, rug/honeypot report, gas estimate, URL-to-markdown and more. x402 v2, USDC, no API key or signup. 10 free verdicts per IP per day.
Output
A JSON object containing four derived representations of the input text: a URL-safe slug, a deterministic UUID (v4-formatted), a Base64 encoding, and a hex SHA-256 hash digest.
Example use cases
Generating a SHA-256 fingerprint for content
“Can you give me the SHA-256 hash of the string 'my-contract-payload-v1' so I can use it as a fingerprint?”
Creating a URL-safe slug from arbitrary text
“Turn the phrase 'My Awesome Blog Post Title!' into a URL-safe slug for me.”
Base64-encoding a text value for storage
“Base64-encode the string 'user:password123' so I can include it in an authorization header.”
Technical details
Endpoint
GEThttps://api.capousd-student-tools.me/v1/util/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple text encodings and hash formats in a single call without managing API keys or signup — especially useful for AI agents operating on Base via x402 micropayments. Prefer it over separate hashing libraries when running in a stateless agent context that can't import crypto dependencies.
Side effects
- Missing or empty 'text' query parameter returns a validation error
- Input text with zero length is rejected by the minLength:1 constraint
- Exceeding the 10 free verdicts per IP per day quota without payment may result in a 402 Payment Required response
- Malformed x402 payment header causes a 402 or 400 error
