How this service works
Machine-verifiable standing under explicit authority and bounds.
Output
Returns a JSON object containing a signed evaluation record with a determination outcome (e.g. 'RECOGNIZED WITH BOUNDARIES'), a list of any required-but-missing fields, a not_sealed_mark boolean, an Ed25519 signature (algorithm, base64url value, and public key), and a SHA-256 hex record hash for verification.
Example use cases
Agent authorization pre-check
“Before my AI agent acts on behalf of 'DataStream LLC', verify its standing under WHP authority using the claim 'DataStream LLC holds a valid operator license for automated data distribution' and give me a signed determination I can attach to downstream requests.”
Publishing rights verification
“I need to verify that 'Horizon Press' has recognized standing as a WHP-affiliated publisher — submit the claim 'Horizon Press is authorized to distribute WHP-licensed content in the European market' and return the signed evaluation record.”
Compliance evidence for a legal claim
“We're submitting a compliance report and need machine-verifiable proof — evaluate the standing of 'Julia Marchetti' with the claim 'Julia Marchetti is a registered WHP authority holder with editorial bounds for academic publications' and send me the signed record hash.”
Technical details
Endpoint
POSThttps://standing-guard-service.lovable.app/v1/patch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, machine-verifiable determination of a subject's standing under Wheeler Hubbell Publishing authority — especially when downstream systems or agents require an auditable, tamper-evident credential (Ed25519 signature + record hash). Prefer it over generic identity checks when WHP-specific authority and bounds are the relevant framework, or when you need a structured outcome with explicit boundary conditions and provenance tracking.
Side effects
- Missing required fields (subject or claim) returns a validation error
- Claim exceeds 4000-character limit causing request rejection
- Subject string exceeds 2000-character limit
- Invalid body structure or wrong bodyType causes a 400-style error
- Payment not received or insufficient USDC causes x402 payment-required rejection
- Service unavailable on lovable.app hosting returns 5xx
- Malformed provenance object may result in incomplete evaluation without error
