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 jwk-to-pem-converter-5561e2d5 -d '<json body>'
```

Example prompt: Can you convert this JWK object into a PEM-encoded key for me? Here's the JWK: {"kty":"RSA","n":"0vx7...","e":"AQAB"}.

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use JWK-to-PEM conversion without setting up a local cryptographic library or runtime. Ideal for agents that occasionally need to transform key formats in automated pipelines, or when operating in environments without native JWK parsing support.

## Known failure modes

- Invalid or malformed JWK object returns an error response
- Unsupported key type (e.g. non-RSA, non-EC) may fail conversion
- Missing required JWK fields (e.g. 'kty', 'n', 'e' for RSA) cause processing errors
- Empty or null JWK input returns failure status
- Network or payment processing errors return 402 or 5xx

## Output

Returns a JSON object indicating the result of the conversion, including a 'result' field containing the PEM-encoded key string and a 'status' field confirming success. The PEM output can then be used directly in cryptographic operations, TLS configurations, or JWT verification libraries.
