How this service works
ID + hash utilities: uuid, nanoid, sha256/512/1, md5, base64/base64url/hex encode+decode. Pay-per-call in USDC.
Output
Returns the computed output for the requested operation — a UUID or nanoid string for ID generation, a hex digest string for hash operations (SHA-256, SHA-512, SHA-1, MD5), or an encoded/decoded string for base64, base64url, and hex conversion operations.
Example use cases
Unique ID for new database row
“I need a fresh UUID to use as the primary key for a new user record I'm about to insert into my database.”
Checksum verification string
“Compute the SHA-256 hash of this string for me: 'order-payload-20240601-abc123' — I want to use it as a data integrity checksum.”
Base64 encode a token
“Base64-encode this string for me so I can safely include it in a URL: 'user:supersecretpassword123'”
Technical details
Endpoint
POSThttps://build-4c941cab041172e9439ece2f.emblem.build/pub/tasks/x402-onchain/api/idWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call cryptographic hashing, UUID/nanoid generation, or base64/hex encoding without managing libraries or infrastructure. Ideal for agents that occasionally need ID or hash utilities without spinning up a runtime environment.
Side effects
- Unsupported operation type returns an error indicating invalid op parameter
- Missing input data for hash or encode/decode operations returns a validation error
- Malformed base64 or hex input for decoding returns a decode error
- Payment failure or insufficient USDC balance blocks the call with a 402 response
