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 whp-standing-audit-wheeler-hubbell-publishing-6464d6fc -d '<json body>'
```

Example prompt: Run a WHP Standing audit for the subject 'Acme Corp LLC' under the claim 'Licensed to operate as a registered investment adviser in New York State' and give me back the signed compliance record with its hash.

## When to prefer this

Choose this endpoint when you need a cryptographically signed, machine-verifiable standing record — not just a yes/no validation — especially when the result must be stored, audited, or passed to a third party as tamper-evident proof. It is purpose-built for compliance workflows requiring Ed25519 attestation under the WHP authority framework, making it distinct from general identity verification or simple boolean checks.

## Known failure modes

- Missing required 'subject' or 'claim' fields returns a 400 validation error
- Claim or subject strings exceeding maxLength limits (4000 and 2000 characters respectively) are rejected
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Malformed JSON body or incorrect bodyType returns a parse error
- Service unavailability on lovable.app hosting returns a 503 or timeout

## How this service works

Machine-verifiable standing under explicit authority and bounds.

## Output

A JSON object containing: a signed compliance audit record (typed as SignedComplianceAudit, with a not_sealed_mark flag), an Ed25519 digital signature (algorithm, base64url-encoded value, and public key), and a SHA-256 hex hash of the record — together enabling downstream systems to cryptographically verify the authenticity and integrity of the standing assertion.
