| Package map for the web access capability family: the search/fetch service, its provider backends, and the model-facing tools that consume them. | package-group |
web/ — web access capability family
English | 中文
Summary
The web/ packages let models search the public web and fetch HTTP(S) pages through the web_search and web_fetch tools. Deployments can choose Exa, Perplexity, or DeepSeek for search and anonymous HTTP(S) access for fetch; availability and resource limits depend on the configured provider. Use this family for search and page retrieval, not interactive browsing, content extraction, or per-URL policy enforcement. Models receive consistent tool behavior, cancellation, and error reporting when providers change.

Start with the subsystem reference for the shared vocabulary, then the design decision behind the single provider-selection service.

WebError, and public-address enforcement. - Web capability seam decision — why search and fetch share one provider-selection service.
