Fetch models via API

const models = await client.models.list();
const gpt = await client.models.retrieve("gpt-5.6-sol");

models = client.models.list()
gpt = client.models.retrieve("gpt-5.6-sol")

curl "https://www.ninjachat.ai/api/v1/models?modality=text&capability=tools"

GET /models and GET /models/{id} are public — no API key needed. Each model carries id, name, modality (text, image, image_edit, video), status, servable, brand, description, capabilities, contextWindow, maxOutputTokens, pricing (meteredPromptPerToken, meteredCachedPromptPerToken, and meteredCompletionPerToken for chat; perUnitUsd for media), providers (each rail with role, available, trainsOnData, zeroRetentionAvailable), supply (rail counts and redundancy), and supportedParameters. ninja/auto additionally reports virtual: true and its router.candidates. Filter with query parameters: modality, provider, capability, availability, and virtual=false to hide the router entry.
