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 anonymous-credential-issuer-mcp-cf004242 -d '<json body>'
```

Example prompt: Issue an anonymous credential for me based on this attribute data so I can prove my eligibility without revealing who I am: {"age_over_18": true, "country": "US"}.

## When to prefer this

Choose this endpoint when you need to issue credentials that preserve user privacy through anonymous or zero-knowledge cryptographic techniques, particularly when users must prove attributes (age, membership, eligibility) to third parties without disclosing identity. Prefer over standard credential issuance when privacy is a core requirement.

## Known failure modes

- Invalid or malformed data input returns an error response
- Missing required attribute fields causes credential issuance failure
- Cryptographic backend errors may result in generation failures
- Malformed JSON in the data field returns a 400-level error
- Service unavailability or overload may return 5xx errors

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns an anonymous cryptographic credential or token that encodes the requested attributes in a privacy-preserving form, allowing the holder to prove claims without revealing their underlying identity or personal data.
