能力清单

工具	说明
factgrid_package_upgrade_advisory	Before upgrading an npm or PyPI dependency, find out what breaks. Returns publisher-declared breaking changes between two published versions: yanked releases and the reason, entry points removed from the exports map, CommonJS-to-ESM switches, raised Node or Python floors, new peer dependency requirements, and licence changes. Every finding carries the exact metadata field and its before/after value so you can verify it against the registry yourself. Registry metadata only - it does not read changelogs or source, so behavioural changes are out of scope and it says so.
factgrid_api_breaking_changes	TEMPORARILY OFFLINE for third-party APIs, pending revalidation - it returns no data and bills nothing. For npm or PyPI packages use factgrid_package_upgrade_advisory instead, which is live. Find what BREAKS between two versions of a third-party API (Stripe, OpenAI, Supabase, and thousands more). Use this when code that calls an external API fails after a version bump, when writing an integration against an API whose version you are unsure of, or before upgrading a dependency that wraps an HTTP API. Returns removed endpoints, removed or renamed parameters, type changes, newly required parameters, and a migration note for each. Do NOT use for general programming questions or for APIs you control.
factgrid_api_schema	Look up the exact request and response shape of a third-party API endpoint at a specific version — parameter names, which are required, and their types. Use this before writing or repairing a call to an external HTTP API, instead of guessing parameter names from memory. Do NOT use for APIs in the local codebase.
factgrid_integration_brief	Get everything needed to write ONE working call to a third-party API: base URL, authentication scheme, required parameters with types, request body shape, and documented response codes — in a single response. Use this BEFORE writing or repairing a call to an external HTTP API, instead of guessing parameter names or auth headers from memory. Prefer this over factgrid_api_schema when you intend to actually make the call: it returns the callable shape rather than a list of endpoints. Every field is read from the publisher's specification — a rate limit or auth scheme the spec does not state is reported as unstated, never guessed. Do NOT use for APIs in your own codebase.
factgrid_discover_api	Find WHICH third-party API can do something, across an index of over a thousand services. Use this when you know the capability you need but not which provider offers it — "send an SMS", "verify a phone number", "create an invoice", "manage DNS records". Returns matching services ranked by how many of their endpoints relate to the capability, with example endpoints. Follow up with factgrid_integration_brief on the service you pick to get the callable shape. Do NOT use when you already know which API you are calling — go straight to factgrid_integration_brief.
factgrid_create_topup_link	Create a secure Stripe checkout link to add prepaid credit to the calling API key. Use this when a query has returned HTTP 402 (payment required) or the balance is running low. YOU CANNOT COMPLETE THE PAYMENT YOURSELF — card details require a human. Return the link to your operator and ask them to open it. Credit appears on the key within seconds of payment; no card details ever reach this service.
factgrid_component_spec	Look up verified electronics component facts: pin-by-pin assignments, operating voltage range, package type, and drop-in alternative part numbers. Use when wiring or reviewing a hardware design, selecting a substitute part, or checking a pin assignment before committing to a PCB layout. Accuracy is best-effort — always confirm against the manufacturer datasheet before manufacturing.
factgrid_deprecation_scan	Find WHICH endpoints or parameters of a third-party API are deprecated, sunset dates, and replacement operations. Use this before upgrading an API integration or auditing code for deprecated API calls. Returns spec-declared sunset dates and replacements; unstated fields are explicitly marked as unstated. Do NOT use for APIs in your own codebase.
factgrid_auth_playbook	Get the authentication schemes, required scopes, declared rate-limit headers, and complete error code table for a third-party API. Reuses verified specification details so an agent does not burn tokens rediscovering 401/403/429 semantics. Rate limits not declared by the spec are reported as unstated. Do NOT use for APIs in your own codebase.
factgrid_subscribe_spec_changes	Subscribe to specification changes or demand auto-ingest updates for a third-party API. Pass an optional webhookUrl to receive HTTP POST callbacks when the API spec is published or auto-ingested. Do NOT use for APIs in your own codebase.
