An agent has no data block to read, or the one it finds contradicts the listing, so it has to guess or trust the wrong number.

Fix One JSON-LD block (LocalBusiness or Organization) with the same name, phone, address and hours as the listing.

The fix, as a brief for a coding agent

Goal: Publish schema.org JSON-LD that matches the listing
Site: https://higgsfield.ai/explore (Higgsfield)
Issue: No structured data
Fix: Add a <script type="application/ld+json"> block to the homepage describing the business: @type LocalBusiness or the closest subtype (Plumber, Restaurant, Hotel…; Organization or SoftwareApplication for a software company), with name, url, telephone in E.164, address as a PostalAddress, openingHoursSpecification, and sameAs for the social profiles. Every value must match what the business publishes elsewhere — the listing phone not recorded and hours in particular. Validate at validator.schema.org and re-fetch.
Evidence:
  hasHours: false
  mismatch: false

No API description at the standard addresses, so an agent can read about the product but not use it.

Fix An OpenAPI document at /openapi.json, linked by a Link header or /.well-known/api-catalog.

Goal: Publish a machine-readable API description where agents look
Site: https://higgsfield.ai/explore (Higgsfield)
Issue: No API description found
Fix: Publish an OpenAPI 3.x document at /openapi.json (and/or /openapi.yaml); add a Link response header on the homepage — Link: </openapi.json>; rel="service-desc" — and publish /.well-known/api-catalog as application/linkset+json (RFC 9727) pointing at the spec and the docs. Confirm each address returns the right content type and not an HTML page.
