How this service works
Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.
Output
A JSON object containing a boolean 'ok' field, the utility name used, a unique requestId for tracking, the charged credits consumed, and the encrypted or decrypted result data.
Example use cases
Encrypt secrets before storage
“I need to encrypt this sensitive config value 'db_password=hunter2' with a symmetric key before saving it to my database — can you do that and give me the ciphertext?”
Decrypt received encrypted payload
“I received this ciphertext from a partner system and need to decrypt it using our shared symmetric key 'a1b2c3d4e5f6g7h8' — can you decrypt it and give me the plaintext?”
Protect user PII in transit
“Before I send this user's SSN '123-45-6789' over to a third-party service, encrypt it symmetrically so only I can decrypt it on the other end.”
Technical details
Endpoint
POSThttps://util.beauty/v1/crypto/symmetricWhen to prefer
Choose this endpoint when you need quick, serverless symmetric encryption or decryption without managing your own crypto infrastructure, especially in agent workflows that benefit from pay-per-use pricing via x402 USDC micropayments. Ideal for one-off encryption tasks, protecting secrets before storage, or decrypting partner payloads in an AI pipeline where spinning up dedicated crypto services is overkill.
Side effects
- Invalid or missing encryption key returns an error response
- Unsupported algorithm specified causes a 400-level error
- Malformed ciphertext during decryption results in a decryption failure
- Insufficient prepaid credits or failed x402 payment blocks the request
- Missing required body fields returns a validation error
