The research providers a run can use

The Deep Research provider catalog for the token owner: every provider's id (slug), label, category, description, icon and docs link, its key mode (platform: it runs on Fuse's key; byok-required: the user must save their own key), whether this user has saved one (hasUserKey), where the key that would be used comes from (source: platform, byok or none), whether research runs may call it (allowedInRuns) and, when the provider can back an enrichment waterfall, the channels it fills and the input-field combinations it accepts. Keys are never returned. The catalog informs BYOK settings and smart-column provider choice; a run itself has no provider selector. Rate limit: 30 requests per minute, 1000 per day.
