## Tools
- apis_io_search - START HERE. Federated overview of the APIs.io catalog for a query: the top matching APIs, providers, AND tags in one call, each with its total match count. Filter by tags, artifact types, industry, region, rating band. `limit` is per section. To page/sort the full list of ONE type, use find_apis / find_providers / find_tags; for one entity, get_api / get_provider. Endpoint: https://apis.io/mcp
- find_apis - Paginated, sortable list of APIs across providers — filter by tag, provider, artifact type, industry, region, or rating band. Use apis_io_search first for a cross-type overview. Endpoint: https://apis.io/mcp
- get_api - Full detail for one API by aid (provider:api-slug); set include=["content"] to inline artifact bodies. Endpoint: https://apis.io/mcp
- find_providers - Paginated, sortable list of providers — filter by text, tag, artifact type, industry, region, rating band, or access model (pricing/onboarding/try_now/public). Use apis_io_search first for a cross-type overview. Endpoint: https://apis.io/mcp
- get_provider - Full detail for one provider: profile, rating, and the APIs it publishes. The heavy `collections` and `common` sections are omitted by default (their counts are still reported) — pass view=full for the whole document, or fields=["common"] for a section. Narrow for cheap reads: fields=["score"] returns just the rating. Relative artifact URLs are resolved to absolute, fetchable ones. Endpoint: https://apis.io/mcp
- find_tags - Paginated, sortable list of tags in the taxonomy. Use apis_io_search first for a cross-type overview. Endpoint: https://apis.io/mcp
- get_tag - One tag: its metadata, neighbor tags, and a top sample of its providers and APIs (with totals). Use find_apis?tags=slug / find_providers?tags=slug for the full ranked list, or view=full here. Endpoint: https://apis.io/mcp
- find_industries - Browse industry verticals; sort by provider/API count. Endpoint: https://apis.io/mcp
- get_industry - One industry: metadata + a top sample of its member providers (ranked, with the total). Use find_providers?industry=slug for the full list, or view=full here. Endpoint: https://apis.io/mcp
- find_regions - Browse geographic regions; sort by provider/API count. Endpoint: https://apis.io/mcp
- get_region - One region: metadata + a top sample of its member providers (ranked, with the total). Use find_providers?region=slug for the full list, or view=full here. Endpoint: https://apis.io/mcp
- find_areas - Browse the API Evangelist areas taxonomy (authentication, webhooks, payments, …) — curated, scored provider indexes. Search by text; sort by provider count. Endpoint: https://apis.io/mcp
- get_area - One area: metadata, its dedicated site link, and a top sample of member providers (with the total). Use find_providers?area=slug for the full list, or view=full here. Endpoint: https://apis.io/mcp
- find_ratings - Ranked ratings leaderboard — filter by band, score range, trend, or facet threshold. Sort by composite (default), delta (biggest gainers), or any quality facet (governance, security, …) to rank providers by that dimension. Endpoint: https://apis.io/mcp
- get_provider_rating - One provider's full rating breakdown (composite, band, trend, six facets). Endpoint: https://apis.io/mcp
- get_rating_rubric - The rubric — bands, facet weights, trend thresholds — so an agent can interpret any score. Endpoint: https://apis.io/mcp
- find_artifacts - Find artifacts of ANY one type across the catalog — the cross-type entry point. Each type also has a dedicated find_<type> tool (find_mcp, find_rules, find_scopes, …) with sorts and filters unique to that type; prefer those when you know the type. Types: mcp, skills, rules, arazzo, plans, rate-limits, finops, collections, asyncapis, graphql, json-ld, channels, examples, json-schemas, json-structures, openapis, postman, vocabularies, apis-json. PRO: scopes, security. include=["content"] inlines bodies. Endpoint: https://apis.io/mcp
- compare_providers - PRO — Compare 2+ providers side by side: composite/band, per-facet leaders, and an artifact-coverage matrix. Endpoint: https://apis.io/mcp
- gap_analysis - PRO — For each provider: high-value artifacts it lacks (MCP, Arazzo, Rules, Skills…), what its peers commonly publish but it lacks, and its score vs the peer median — plus stack-level gaps across the set. Endpoint: https://apis.io/mcp
- whats_changed - PRO — What changed in the catalog since a date: providers added/updated, plus rating movement (up/down) from the latest scoring build. Endpoint: https://apis.io/mcp
- recommend_stack - Design an API stack — the best-rated catalog provider per capability, assembled into a stack. FREE preview = the top pick per capability; PRO = alternatives, per-pick artifact gaps, and an exportable APIs.json + Arazzo hint. Decompose the domain into capabilities first, then pass them here. Endpoint: https://apis.io/mcp
- get_provider_artifacts - Every artifact a provider publishes — provider-level (MCP, security, scopes, rules, agentic-access) and per-API (OpenAPI, Arazzo, overlays, reference docs) — grouped by type with counts. by_type_counts is the full summary; pass `type` (e.g. OpenAPI, MCP) to scope the artifacts list to one type, since an unfiltered provider can be 250+ entries. Endpoint: https://apis.io/mcp
- get_api_artifacts - One API's artifacts grouped by type (by_type_counts is the full summary); pass `type` to scope the list to one type (synonym-aware: MCP matches MCPServer), include=["content"] to inline the bodies. Endpoint: https://apis.io/mcp

- find_rating_movers - PRO — The biggest rating movers (up and down) since the previous scoring build. Endpoint: https://apis.io/mcp
- story_leads - OWNER — The weekly "what's worth writing" rollup: ranked story leads from the demand map crossed with rating movement — unmet demand (searched, no result), risers/fallers, and hot-but-thin capabilities. Each lead is a headline, its signal, and a suggested angle. include=["raw"] appends the underlying demand report. Endpoint: https://apis.io/mcp
- export_dataset - BUSINESS/license tier — the WHOLE dataset in one pull (not a 100-row page): `ratings` (every rated provider with facets, trend, rubric + provenance) or `providers` (the catalog with coverage + score).

Groups: profile, onboarding, artifacts (free); rating, insights (Pro). Free base. Endpoint: https://apis.io/mcp
