What this server can do

79 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

add_to_list(id, members)

PRO — Add providers/APIs (by slug or aid) to one of your lists. Required: id, members.

apis_io_search(q, area, band, sort, tags, limit, match, region, industry, min_score, providers, artifact_types)

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.

company_gaps(slug)

A company's weakest investment dimensions — where it is thin and a vendor could sell in. Pro. Required: slug.

compare_providers(providers)

PRO — Compare 2+ providers side by side: composite/band, per-facet leaders, and an artifact-coverage matrix. Required: providers.

create_list(name, members)

PRO — Create a named, persistent list (a shortlist / stack you own) of providers or APIs. Requires an apis.io API key. Required: name.

delete_list(id)

PRO — Delete a list you own. Required: id.

delete_saved_search(id)

PRO — Delete a saved search you own. Required: id.

enrich_provider(id, fields)

One call, pick your field groups — resolves a slug OR any identifier and returns exactly the groups you ask for, instead of chaining get_provider + get_provider_rating + get_provider_artifacts + get_provider_onboarding. Groups: profile, onboarding, artifacts (free); rating, insights (Pro). Free base. Required: id.

get_api(aid, include, artifact_types)

Full detail for one API by aid (provider:api-slug); set include=["content"] to inline artifact bodies. Required: aid.

get_api_artifacts(aid, type, include)

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. Required: aid.

get_area(slug, view, limit)

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. Required: slug.

get_area_leaders(slug, limit)

PRO — Top-rated providers in a curated API Evangelist area. Required: slug.

get_provider(slug, view, fields)

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. Required: slug.

get_provider_artifacts(slug, type)

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. Required: slug.

industry_gap_analysis(slug, min_share)

PRO — Valuable artifact types (MCP, Arazzo, Rules, Skills…) commonly missing across a whole industry — where the vertical is under-served. Required: slug.

Required: capabilities.

resolve(identifier)

Resolve ANY identifier — website URL, domain (stripe.com), or GitHub org (github.com/stripe) — to the apis.io provider it belongs to. Use this when you have a URL, not a slug. Free. Required: identifier.

run_saved_search(id, limit)

PRO — Re-run one of your saved searches against the live catalog and return current matching providers. Required: id.

save_search(q, area, band, name, tags, match, region, industry, min_score, artifact_types)

PRO — Persist the current search criteria as a named saved search you own, so you can re-run it and get net-new results later. Criteria use the same filters as apis_io_search. Requires an apis.io API key. Required: name.

saved_search_net_new(id)

PRO — What is NEW for a saved search since you last checked: providers that newly match your criteria. Advances the delta cursor, so each call reports only what changed since the previous call. The agent-native version of the demand report. Required: id.

story_leads(include)

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.

vc_portfolio(band, page, slug, sort, limit, min_score, in_network, is_provider)

A VC firm's portfolio companies, each matched to the network and rated. Filter is_provider=true (only API providers), in_network=true, band, or min_score; sort by score (default), api_count, or name. The demand-side view of who a fund has backed. Free. Required: slug.

whats_changed(limit, since)

PRO — What changed in the catalog since a date: providers added/updated, plus rating movement (up/down) from the latest scoring build. Required: since.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
