PBKDF2 Key Derivation API
x402
PBKDF2 Key Derivation API is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.016/call, status unknown (last checked 2026-09-14).
Derives a cryptographic key from a password using PBKDF2 with configurable iterations, salt, and hash algorithm

How this service works
PBKDF2 key derivation, password hashing, KDF, scrypt alternative, stretch password, derive encryption key, password-based key derivation, iterations, salt. Derive a cryptographic key from a password using PBKDF2 with configurable iterations, salt, and hash algorithm. Accepts payment on Base or Solana — either network works.
Output
Returns a derived cryptographic key (typically hex-encoded) computed via PBKDF2 using the provided password, salt, iteration count, and hash algorithm — suitable for use as an encryption key or secure password hash.
Example use cases
Example prompt
“Derive a 256-bit encryption key from the password 'MyS3cretPass!' using PBKDF2 with SHA-256, a salt of 'randomsalt123', and 100000 iterations.”
Technical details
Endpoint
GEThttps://api.x402node.dev/crypto/pbkdf2When to prefer
Use this endpoint when you need PBKDF2-based key derivation or password stretching in a serverless/agent context without running local crypto libraries. Prefer this over generic hash endpoints when you need iterated key derivation (not just a single hash), configurable salt, and tunable work factor for security. Good for deriving AES keys from passphrases or storing password-derived keys.
Side effects
- Missing required fields (password or salt) returns 400 Bad Request
- Invalid hash algorithm name returns 400 with unsupported algorithm error
- Iteration count too low or zero returns validation error
- Key length out of supported range returns error
- Payment not provided or insufficient USDC returns 402 Payment Required
- Server-side computation timeout for extremely high iteration counts
