func NewProviderFetcher(providers catalogs.ProvidersReader, opts ...ProviderOption) *ProviderFetcher

func (pf *ProviderFetcher) FetchModels(ctx context.Context, provider *catalogs.Provider, opts ...ProviderOption) ([]catalogs.Model, error)

FetchModels fetches available models from a single provider's API. It handles credential resolution, client creation, and API communication. When a provider quarantines malformed records, FetchModels returns the valid siblings together with a non-nil *sourcepayload.QuarantineError wrapped in a SyncError. Callers may consume the partial result only as degraded evidence.

Example:

fetcher := NewProviderFetcher(providers, WithProviderClientFactory(factory))
models, err := fetcher.FetchModels(ctx, provider)

With options:

fetcher := NewProviderFetcher(providers,
    WithProviderClientFactory(factory),

The endpoint parameter should be the full URL to the API endpoint. FetchRawResponse returns unparsed JSON bytes and fetch statistics.

func (*ProviderFetcher) HasClient
func (pf *ProviderFetcher) HasClient(id catalogs.ProviderID) bool

HasClient checks if a provider ID has a client implementation.

func (*ProviderFetcher) List
func (pf *ProviderFetcher) List() []catalogs.ProviderID

func (*ProviderFetcher) Providers
func (pf *ProviderFetcher) Providers() *catalogs.Providers
