List available models and their pricing.
List every model in the catalog with its context length, modalities, and DA pricing. The catalog is public — no API key required, and reads are never billed.
Related public reads: GET /api/models/{slug} (one model), GET /api/models/{slug}/capabilities, GET /api/models/stats, GET /api/models/facets (filter values), GET /api/models/health.
Each model includes its slug, context window, input/output modalities, and DA pricing (pricing.input_da_per_million, pricing.output_da_per_million). Filter with query params like ?capability=vision, ?provider=anthropic, or ?q=<search>.
