• 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…

• get_prices

  What one call costs on the pay-as-you-go plan, by cost band. FREE — and deliberately so: an agent that learns a price only when it is refused has already been refused by its own wallet. Call this BEFORE budgeting a run of paid tools…

• get_playground_apis

  Curated APIs that are SAFE TO EXPERIMENT WITH — no key (or an instant, free, self-serve key), no cost, and no real-world side effects. Free, and deliberately so: this is where you start if you are new here. Every entry carries an…

• find_apis

  Paginated, sortable list of APIs across providers — filter by tag, provider, artifact type, industry, region, or rating band. Matching is LEXICAL: `q` searches the API's own name and description. apis_io_search reports a larger API total…

• get_api

  Full detail for one API by aid (provider:api-slug); set include=["content"] to inline artifact bodies. Results carry `next`: the sub-resources that exist for this entity and the exact tool call that retrieves each, computed from this…

• find_providers

  Paginated, sortable list of providers — filter by text, tag, artifact type, industry, region, rating band, access model (pricing/onboarding/try_now/public), or DIRECTION (accepts_writes/min_acting — whether the surface takes a write or…

• 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"]…

• find_tags

  Paginated, sortable list of tags in the taxonomy. Filter by `axis` to separate MARKETS (a business someone is in) from CAPABILITIES (the name of a resource in somebody's OpenAPI) — the single most useful distinction in the vocabulary, and…

• get_tag

  One tag: its metadata, neighbor tags, and a top sample of its providers and APIs (with totals). `provider_count` counts companies that classify THEMSELVES here; `api_provider_count` counts the ones reached only through an API or operation…

• find_industries

  Browse industry verticals; sort by provider/API count.

• 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. Results carry `next`: the sub-resources that exist for this entity and the…

• find_estates

  Browse corporate estates — one COMPANY whose API surface is spread across many provider records (Amazon 237, Salesforce 27, Cisco 37). Ranked by member count. Use this when two slugs look like separate vendors and you need to know whether…

• get_estate

  One estate: the owning provider, the full member roster with per-member API counts and bands, and the estate-wide rating. Use get_provider_estate(slug) to go the other way, from a provider to the company that owns it.

• get_provider_estate

  Which corporate estate a provider belongs to, if any. Answers 200 with estate:null when the provider stands alone — that is a measured absence, not a missing record.

• find_regions

  Browse geographic regions; sort by provider/API count. Returns the 18 regions themselves. The collection also holds region x industry crossover pages (nordics-healthcare and 1,097 more); those are excluded unless you ask for them with type.

• 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. Results carry `next`: the sub-resources that exist for this entity and the exact…

• find_countries

  Browse the country dimension — the finest of the four place taxonomies, and the one a buyer usually names ("who is in Germany"). Peer to find_industries / find_regions / find_areas. Search by text; sort by provider count. Membership is…

• get_country

  One country: metadata, counts, and a top sample of member providers (with the total). Use find_providers?country=slug for the full ranked list, or view=full here.

• find_areas

  Browse the API Evangelist areas taxonomy (authentication, webhooks, payments, …) — curated, scored provider indexes. Search by text; sort by provider count.

• 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. Results carry `next`: the sub-resources that exist for this entity and…

• find_regulations

  Browse the laws, statutes and accreditations the catalog tracks, each joined to the countries, regions and industries it binds. Filter by scope=horizontal to get the regimes that reach a provider with NO industry tag at all, which is the…

• get_regulation

  One regulation: what it is, its jurisdiction and scope, a link to the law itself, and reaches[] — the country, region and industry cohorts this regime binds. Use reaches[] to go straight to the affected members with find_providers.

• find_extensions

  Browse every OpenAPI `x-` specification extension harvested across the catalog, with the provenance the OpenAPI Initiative registry does not carry: who publishes it, in how many documents, where in the document it appears, and what shape…

• get_extension

  One OpenAPI specification extension: its publishers, occurrence and document counts, where it appears, and the value shapes observed. CHECK is_api_evangelist BEFORE treating a key as provider-originated — some of these are published by…

• 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. Priced per…

• get_provider_rating

  One provider's full rating breakdown (composite, band, trend, six facets). Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

• find_cohorts

  START HERE for market-level questions. Every scored population of providers in the catalog — tags, industries, regions, areas and VC portfolios — as one browsable index. Filter by kind, minimum population, or promotion tier…

• get_cohort

  One cohort: its identity, its population, and the full member roster with each provider's Kin Score and agent readiness. Understanding plan. The analysis parts (stats/rankings/scores/capabilities) are Understanding too — they moved down…

• find_tag_groups

  START HERE for capability-map questions. The 1,500+ tag groups the catalog computes — sets of tags that demonstrably travel together across providers (Cards, Logistics, Wealth Management, Observability), the layer between a single tag and…

• get_tag_group

  One tag group: its member tags and the full provider roster resolved from the catalog, each with Kin Score and agent readiness. Filter the roster by industry, region, country or area. Free; the DISTRIBUTION over the roster (`stats`) needs…

• tag_group_tags

  The member tags of one tag group, each joined to its catalog record — provider count, api count, tag quality band and composite. Use it to see what a group is actually made of before trusting the group as a market. Priced B1…

• cohort_stats

  UNDERSTANDING — the DISTRIBUTION for a whole market: Kin Score mean/median/min/max/stdev, agent-readiness spread, band split, per-facet averages, and artifact adoption rates. This is the market-stats sheet from a Trend Report, computed…

• cohort_rankings

  UNDERSTANDING — the leaderboard for a market, on TWO axes: rank by Kin Score composite AND rank by agent readiness. The two orders differ, and the gap between a provider's two ranks is usually the story. Priced per result — $0.005 per…

• cohort_scores

  UNDERSTANDING — facet-level scores for every member of a cohort, each with the cohort average and the delta against it. A 60 in governance means nothing until you know the market sits at 45; this is the endpoint that says so. Priced per…

• find_operations

  UNDERSTANDING — CATALOG-WIDE operation search: which providers expose a path matching your terms. "Who has a POST /refunds" had no answer before this — tags are what a company says about itself, a path is what its API accepts. Terms match…

• deprecated_operations

  UNDERSTANDING — every provider publishing at least one operation marked deprecated in its own OpenAPI, ranked by how many. The lifecycle view of the catalog: 8,297 deprecated operations across 681 providers, which nothing could see…

• cohort_history

  UNDERSTANDING — the SET-LEVEL time series: how a whole market's Kin Score and agent readiness moved, build by build. There was a per-provider series and a whole-dataset licence and nothing between them, so "how has banking moved over six…

• cohort_failures

  UNDERSTANDING — what a whole market gets WRONG: the agent-readiness checks its members most commonly fail, ranked by what fixing each would move the cohort mean. The inverse of gap_analysis, which says where a market is under-served; this…

• cohort_capabilities

  UNDERSTANDING — what every member of a cohort actually publishes: artifact counts by type plus the agent-readiness dimensions each one satisfies. The capability matrix behind a market report. Large cohorts come back in byte-budgeted…

• compare_cohorts

  UNDERSTANDING — two markets side by side on one rubric: "is US payments further along than UK banking?" Returns both distributions plus the deltas on score, agent readiness, every facet and every adoption rate. A question a written report…

• get_provider_operations

  Every operation a provider exposes, across all of its OpenAPIs — method, path, operationId, summary, which API it belongs to, and whether it is deprecated. The shortcut for "what can I actually call here?", which otherwise means fetching…

• get_provider_tools

  Every MCP tool a provider ships, with the operation each one wraps and its auth. Reports provenance per tool: `first-party` means the provider publishes that server, `derived` means API Evangelist generated a candidate tool list from…

• get_provider_schema

  Every JSON Schema a provider publishes — the data shapes their API works in, in one list, without walking their artifacts. Free.

• get_provider_facets

  UNDERSTANDING — one provider's score broken into its facets (discoverability, contract quality, governance, operational transparency, developer ergonomics, commercial clarity) plus any regulatory regime that applies. The composite is one…

• get_agent_readiness

  EXPLORE — the agent-readiness dimensions and standalone score for ONE provider (spec presence, MCP server, auth clarity, idempotency, error semantics, rate-limit signal, well-known catalog, consent identity, dry-run…). A STANDALONE score…

• find_agent_readiness

  UNDERSTANDING — the agent-readiness leaderboard across the whole catalog. Rank providers by agent readiness, and filter to those that DO satisfy (has) or do NOT satisfy (missing) specific dimensions — e.g…

• agent_readiness_dimensions

  UNDERSTANDING — diffusion: for each agent-readiness dimension, how many scored providers satisfy it, out of how many, as a share. The denominator every "the agent web is/is not here yet" claim needs and almost never has. Priced B1…

• find_capabilities

  START HERE for "what can a business do with these APIs". The business-capability model — 333 top-level capabilities across 28 industries — with how many catalog providers reach each one. Defaults to capabilities the catalog actually…

• get_capability

  One business capability: its definition, its sub-capabilities, the external authorities it cites, and WHICH catalog providers reach it with their ratings. Accepts a slug or a BC id (e.g. "payments-card-management" or "BC-1340"). Free. The…

• get_capability_edges

  UNDERSTANDING — the evidence behind a capability. Every edge that lands on it: the provider, the tag, the exact OpenAPI file, a calibrated confidence, and the QUOTED FRAGMENT OF THE PROVIDER'S OWN CONTRACT that justifies the claim. Only…

• get_provider_business_capabilities

  UNDERSTANDING — what ONE vendor's published APIs let a business DO, rolled up by capability, with the tag-level evidence under each. Answers "what is this vendor actually for" from its own contracts rather than its marketing. NOT…

• get_provider_capabilities

  What one provider publishes, counted by artifact type, with the agent dimensions it satisfies. Free — it is a fact about their own public surface. NOTE: this is artifact counts, NOT business capabilities — for what the vendor lets a…

• get_provider_evidence

  How a provider's score was established, part by part: first-party (they published it), verified (we fetched and confirmed it), or derived (we inferred it). Free — the basis for a claim should never sit behind the claim. Call this before…

• get_rating_rubric

  UNDERSTANDING — the rubric: bands, facet weights, trend thresholds, so an agent can interpret any score. Moved behind the paywall with the ratings data on 2026-08-31. Priced B1 (single-entity synthesis) — $0.01 per call under…

• 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…

• compare_providers

  UNDERSTANDING — Compare 2+ providers side by side: composite/band, per-facet leaders, and an artifact-coverage matrix. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See…

• gap_analysis

  UNDERSTANDING — 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. Priced B2…

• whats_changed

  UNDERSTANDING — What changed in the catalog since a date: providers added/updated, plus rating movement measured FROM THAT DATE — each provider's current score against its score at the first scored snapshot on or after `since`, with `was`…

• recommend_stack

  Design an API stack — the best-rated catalog provider per capability, assembled into a stack. The Understanding preview is the top pick per capability; the full answer adds alternatives, per-pick artifact gaps, and an exportable APIs.json…

• get_provider_apis

  Every API one provider publishes, as a page you can filter — the provider's own catalog rather than the whole network's. Prefer this over find_apis with a `providers` filter when you already know the company: it is the endpoint the…
