# PBKDF2 Key Derivation API

> PBKDF2 Key Derivation API is a paid API for AI agents from kihustle.tech, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Derives a cryptographic key from a password using the PBKDF2 algorithm with configurable salt, iterations, and output length

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pbkdf2-key-derivation-api-30ca64f8 -d '<json body>'
```

Example prompt: Derive a PBKDF2 key from the password 'correct-horse-battery' using the salt 'randomsalt123', with 100000 iterations and an output length of 32 bytes.

## When to prefer this

Choose this endpoint when you need a hosted, pay-per-call PBKDF2 key derivation without setting up your own cryptographic infrastructure. Useful for serverless agents or pipelines that need occasional password-based key derivation without bundling crypto libraries. Not recommended for high-volume or latency-sensitive use cases given per-call pricing and network overhead — prefer a local crypto library for those.

## Known failure modes

- Missing required fields (password, salt, iterations, or length) may return an error or unexpected result
- Extremely high iteration counts may cause timeout or slow response
- Invalid data types (e.g. non-integer iterations or length) may cause a processing error
- Very short salt or password may succeed but produce weak security — no validation enforced
- Ambiguous response schema means error details may not be machine-readable

## Output

Returns a JSON object with a 'result' field containing the PBKDF2-derived key and a 'status' field confirming success. The derived key is the cryptographic output of the PBKDF2 function given the supplied password, salt, iteration count, and desired length.
