Hash Text via x402 Micropayment
x402
Hash Text via x402 Micropayment is a paid API for AI agents from gpt55.558686.xyz, paid per call via x402, $0.0001/call, status down (last checked 2026-09-15).
Computes a cryptographic hash (SHA-256, SHA-512, SHA-1, or MD5) of an input text string, returning the digest in a chosen encoding, paid via x402 USDC micropayment.

How this service works
Low-price OpenAI-compatible GPT-5.5 chat completions and text tools over x402 USDC on Base: $0.0001 compact requests, $0.066667 true max-output requests, no subscription.
Output
A JSON object with an 'ok' boolean, 'tool' name ('hashText'), a 'fetchedAt' timestamp, and the computed hash digest in the requested encoding.
Example use cases
Example prompt
“Can you compute the SHA-256 hash of the text 'Hello, world!' and give me the result in hex encoding?”
Technical details
Endpoint
POSThttps://gpt55.558686.xyz/v1/tools/hash-textWhen to prefer
Choose this endpoint when you need a quick, pay-per-use cryptographic hash of a text string without a subscription, especially when already operating in an x402 USDC micropayment context on Base. Ideal for lightweight, one-off hash computations (SHA-256, SHA-512, SHA-1, MD5) in hex or base64 format at minimal cost ($0.0001 per call).
Side effects
- Missing required 'text' query parameter returns an error
- Unsupported algorithm value (not sha256/sha512/sha1/md5) causes rejection
- Unsupported encoding value (not hex/base64/base64url) causes rejection
- Text exceeds 20,000 character limit returns validation error
- Insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Empty text string (minLength violation) rejected
