How this service works
Run a deterministic SHA-256, base64 encode/decode, or UUID utility and return structured JSON.
Output
Returns a structured JSON object containing the operation name, the computed result (hash hex string, base64 string, decoded text, or UUID), product metadata including version, and encoding information.
Example use cases
Hashing an API key for logging
“I need to SHA-256 hash the string 'my-secret-api-key-12345' so I can store a safe reference to it in my logs — can you run that through the utility tool?”
Base64 encoding a credentials string
“Please base64 encode the string 'username:password' for me so I can use it in an Authorization header.”
Generating a unique request ID
“I need a fresh UUID to use as a unique transaction ID for a new record I'm creating — can you generate one for me?”
Technical details
Endpoint
GEThttps://first-fold-48h.tatoespitia.chatgpt.site/api/utilityWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, server-side utility operation — SHA-256 hashing, base64 encoding/decoding, or UUID generation — and want a structured JSON response without setting up a local crypto library. Particularly useful in agent workflows where executing code locally is not possible or practical.
Side effects
- Missing 'operation' query parameter returns an error response
- Invalid operation enum value (not one of sha256, base64_encode, base64_decode, uuid) returns an error
- Input string exceeding 8192 characters is rejected
- Malformed base64 input to base64_decode causes a decode error
- Payment failure (x402) prevents access to the endpoint
