# Higgsfield provider

Tenant-isolated HTTP adapter for asynchronous images, image-to-video, and talking
presenters. Uses the protocol documented in the official Higgsfield TypeScript SDK.
The SDK's current v2 implementation stores credentials globally and retries POSTs;
this adapter instead resolves credentials per scoped call and submits once.

Inject credentials, trusted authorization, and exact input/output asset host
allowlists. The authority port must check durable request/job ownership, current
rights, qualification, and cost reservation. It must never authorize from caller
strings alone. Use durable orchestration before calling `submit`; this low-level
adapter does not itself provide idempotent submission storage.

For durable orchestration use `lib.content-gen/media/workflow` with
`SqlMediaGenerationStore` from `integration.growth-persistence/marketing`. It saves
the provider request ID before asset ingestion and resumes failed imports through
an idempotent, host-qualified artifact ingestor.

An uncertain submission returns `unknown`; never resubmit automatically. Poll only
known provider job IDs. Ignore provider-returned status/cancel URLs and use the
pinned API origin. Cancellation is unavailable until its semantics are qualified.
Outputs are temporary locations to ingest into the host asset store, not publication
approvals. Responses and errors never include provider headers or raw error bodies.

BYOK only. Managed provisioning, MCP transport, and live provider certification
remain unqualified. HTTP fixture tests do not certify account/model access.

}
```

Other capability declarations:

```json

}
```

## Canonical imports

Import paths and symbols below are catalogue declarations. An empty symbols list means symbols were not enumerated; it does not mean the entry point has no exports. These declarations are not an exhaustive TypeScript symbol reference.

```json
[
  {
    "capabilityId": "package.lssm.tech.integration.provider.higgsfield",
    "from": "@lssm-tech/integration.provider-higgsfield",
    "symbols": []
  }
]
```

## Declared export entry points

Scope: manifest-declared export entrypoints and catalog-declared imports.

Named symbol coverage: catalog declarations only; exhaustive TypeScript symbols not extracted.
