List the selectable query models
The model catalog the model field on POST /query draws from. Returns the default model, every catalog entry, the tier → model-id map, per-phase defaults, and the curate-capable model ids. Only entries with available: true are selectable (others are coming soon and rejected with 400).
Authorizations
Session token from POST /auth/login. Pass as Authorization: Bearer <token>. The alternative X-Pinecone-Api-Key header is also accepted for direct-key auth (used by the Nexus CLI on first contact).
Headers
Date-based contract version. Omit to resolve to the Nexus default version (2026-07, the oldest served version); send unstable for the in-development surface. The resolved version is echoed back on the same header. A present-but-unrecognized value is rejected with 400 unsupported_api_version.
