How this service works
AES encryption, AES-256-GCM, symmetric encryption, authenticated encryption, data encryption, secure encryption, cipher, encrypt string. Encrypt plaintext using AES-256-GCM with a 32-byte key. Returns IV, ciphertext, and authentication tag.
Output
Returns a JSON object containing the initialization vector (IV), the AES-256-GCM ciphertext (encrypted data), and the authentication tag — all necessary to later decrypt and verify the data using the same key.
Example use cases
Example prompt
“Encrypt the string 'Hello, World! This is my secret message.' using AES-256-GCM with the 32-byte key 'mySecretKey12345678901234567890ab' and give me back the IV, ciphertext, and auth tag.”
Technical details
Endpoint
GEThttps://api.x402node.dev/crypto/aes-encryptWhen to prefer
Choose this endpoint when you need authenticated symmetric encryption (AES-256-GCM) via a simple API call without setting up a local crypto library. Ideal for AI agents in serverless or sandboxed environments that cannot execute native crypto code, or when you want a quick, pay-per-use encryption step in a data pipeline.
Side effects
- Key is not exactly 32 bytes — returns 400 Bad Request
- Plaintext is missing or empty — returns 400 Bad Request
- Malformed request body — returns 400 or 422
- Payment not provided or insufficient — returns 402 Payment Required
- Server-side encryption error — returns 500 Internal Server Error
