x402 PBKDF2 Key Derivation API
x402
x402 PBKDF2 Key Derivation API is a paid API for AI agents from x402-hash-api.vercel.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).
Derives a cryptographic key from a password using PBKDF2 with configurable salt, digest algorithm, key length, and iteration count — pay-per-call via USDC on Base

How this service works
Pay-per-call hashing and encoding for AI agents (USDC on Base)
Output
Returns a JSON object containing a 'derivedKey' field with the hex-encoded PBKDF2-derived key of the requested length, computed from the supplied password, salt, digest, and iteration parameters.
Example use cases
Password hashing for user accounts
“I need to securely hash the password 'MyP@ssw0rd!' using PBKDF2 — use salt 'acct-salt-9f2a', sha256, 32 bytes, and 150000 iterations so I can store it safely.”
Encryption key derivation from passphrase
“Derive a 64-byte encryption key from the passphrase 'correct-horse-battery-staple' with salt 'enc-salt-2024', using sha512 and 200000 iterations for maximum strength.”
Deterministic key generation for secrets manager
“Run PBKDF2 on password 'vault-master-key' with salt 'tenant-id-7782', sha256 digest, key length 32 bytes, and 100000 iterations so I can reconstruct the derived key for my secrets vault.”
Technical details
Endpoint
POSThttps://x402-hash-api.vercel.app/api/v1/pbkdf2?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, serverless PBKDF2 key derivation without managing your own crypto infrastructure. It is ideal for AI agents that need on-demand password hashing or key stretching in workflows where spinning up a local crypto library is impractical. Prefer it over raw bcrypt or scrypt endpoints when PBKDF2 compatibility (e.g. FIPS compliance, interoperability with existing systems) is required.
Side effects
- Invalid digest value (must be 'sha256' or 'sha512') returns an error
- Iteration count exceeding 200000 is rejected
- Missing required fields (password or salt) result in a validation error
- Payment failure or insufficient USDC balance blocks the request
- Malformed request body returns a 400-level error
