What it can do
| Tool | What it says it does |
|---|---|
add_to_list | UNDERSTANDING — Add providers/APIs (by slug or aid) to one of your lists. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
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 (single-entity synthesis) — $0.01 per call under pay-as-you-go… |
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 /… |
check_status | INFLUENCE — the status of a check request by id: queued, in_review, running, done, rejected or needs_info, with any notes shared by the reviewer. The id identifies the request, but the Influence plan is now required to read it back. To report an error for free, use report_correction or open an… |
claim_listing | INFLUENCE — ask to claim a listing as yours. Returns 202 with a token and the hosts it will be checked against: publish it as a DNS TXT record, or as a file at /.well-known/apis-io-challenge, and leave it up. A PERSON verifies it and emails you — there is nothing else to call. Track it with… |
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 chunks: while `complete` is false, call again with `cursor` set… |
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 says where it is failing the rubric. Turns "fix your… |
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 months" had no answer. Returns the MEAN over members present… |
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 request plus $0.0002 per record returned (less past 100)… |
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 result — $0.005 per request plus $0.0002 per record returned… |
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 live. Always carries a `coverage` block saying how much of the… |
company_gaps | UNDERSTANDING — A company's weakest investment dimensions — where it is thin and a vendor could sell in. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
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 cannot answer, because a report only ever covers one… |
compare_providers | UNDERSTANDING — Compare 2+ providers side by side: composite/band, per-facet leaders, an artifact-coverage matrix, and each provider's economics — audience, pricing basis, delivery, graded entry cost (USD/month) and marginal cost (USD per unit), with the plan and the quoted figure behind each… |
compose_goal | INFLUENCE — hypermedia for a goal across providers: affordances with full href, HTTP method, safety and idempotence from RFC 9110 semantics, path parameters marked ready or needed against your state, the contract location for the full request schema, matching Arazzo workflows with their next step… |
correct_facts | INFLUENCE — propose corrections to what we say about you: name, description, url, industries, tags. Returns 202 and is applied by a person — an API that let an owner rewrite their own description unreviewed would be a marketing surface, not a catalog. Score and band are not owner-settable and are… |
create_list | UNDERSTANDING — Create a named, persistent list (a shortlist / stack you own) of providers or APIs. Requires an apis.io API key. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
delete_list | UNDERSTANDING — Delete a list you own. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
delete_saved_search | UNDERSTANDING — Delete a saved search you own. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
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 before, because a provider's own deprecated filter needs you to… |
dispute_finding | INFLUENCE — "you say we lack X, here it is." Send the claim in words and a URL that evidences it. Returns 202; a person fetches your evidence, checks it against what we hold, and emails you either way. Open to any paying caller — you should not have to prove ownership before you can tell us our… |
enrich_provider | 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, rating, insights. Understanding plan —… |
export_dataset | LICENCE (sold on the Influence plan) — the WHOLE dataset, not a 100-row page: `ratings` (every rated provider with facets, trend, rubric + provenance), `providers` (the catalog with coverage + score), or `history` (every provider's full score time series — parallel date/composite/agent_readiness… |
export_stack | UNDERSTANDING — Export a designed capability stack as an adoptable APIs.json document (with an Arazzo hint) the team can commit. Priced B3 (bulk export) — $0.002 per row, $0.50 minimum per call under pay-as-you-go; included in Understanding and Influence. See apis://prices. |
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. has="mcp_server,protected_resource_metadata" is the OAuth-capable MCP cohort… |
find_agents | FREE, no account — the A2A agent registry: agents that registered THEMSELVES by serving an agent card and calling register_agent. Each row carries the card URL, the operator, and the last verification of the card (grade, protocol version, transport). This is the door an unattended agent can walk… |
find_apis | Paginated, sortable list of APIs across providers — filter by tag, provider, artifact type, industry, region, or rating band. `q` is lexical over the API's own name and description; include=["via_provider"] adds APIs of providers whose name matched (the union apis_io_search counts). Use… |
find_apis_json | APIs.json indexes across the catalog. The APIs.json discovery documents themselves. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |

find_areas | Browse the API Evangelist areas taxonomy (authentication, webhooks, payments, …) — curated, scored provider indexes. Search by text; sort by provider count. |
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… |
find_asyncapis | AsyncAPI (event-driven) specifications across the catalog. Event/streaming APIs. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
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 reaches; pass all=true for the whole model INCLUDING the ones… |
find_channels | AsyncAPI event channels across the catalog. Individual event channels (topics/streams). Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
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 (report/brief/data). Then call cohort_stats for the distribution… |
find_collections | Postman / Open collections across the catalog. Runnable request collections. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
find_company_insights | Browse profiled companies (Fortune 1000) by name or industry; ranked by overall technology-readiness signal. `industry` takes an insights industry NAME from insights_industries (e.g. "Industrial") — a different vocabulary from the catalog industry slugs find_providers uses — and matches every… |
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 derived and known to be partial: read a count as a floor, not… |
find_estates | UNDERSTANDING — 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 they are one company. Priced B1… |
find_examples | Example payloads across the catalog. Real request/response examples. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
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 the value takes. Search by key or purpose; sort by… |
find_finops | FinOps / billing models across the catalog. How usage is metered and billed. meta carries the billing model (pricing category), method, provenance_date, primary_unit (what the provider bills by) and `template: true` on sweep output that restates the FinOps framework without a unit, meters or a… |

find_industries | Browse industry verticals; sort by provider/API count. |
find_investors | UNDERSTANDING — The reverse portfolio edge: which VC firms in the network back a given provider/company (by slug). The investor COUNT is free; the named firms need Understanding. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See… |
find_json_ld | JSON-LD contexts across the catalog. Linked-data vocabularies. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
find_json_schemas | JSON Schemas across the catalog. Standalone data schemas. Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |

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 path SEGMENTS (all must appear), so q="payment intents"… |
find_overlays | OpenAPI Overlays across the catalog. Documents applied on top of an API contract to add or change what it says. meta says who wrote it (authorship: provider / derived / generated / unmarked), whether the provider hosts it (provider_hosted — the only kind the Kin Score credits), what the actions… |
find_plans | Pricing plans across the catalog. An API's pricing tiers. meta says who wrote the file (method), when it was read (provenance_date), who the page prices for (audience), how (pricing_basis), and whether a price is stale. Filter by q / tags / providers; include=["content"] inlines bodies. Use… |
find_postman | Postman collections across the catalog. Postman-format collections (by reference). Filter by q / tags / providers; include=["content"] inlines bodies. Use find_artifacts for cross-type search. |
find_providers | Paged, sortable, filterable provider list. Size filters need Understanding. Reference: apis://docs/tools/find_providers. |

find_rating_movers | UNDERSTANDING — The biggest rating movers (up and down) since the previous scoring build. Priced per result — $0.005 per request plus $0.0002 per record returned (less past 100), capped at $0.50 a request, under pay-as-you-go; included in Understanding and Influence. Estimate first at… |
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. Each row also carries agent_readiness {score, band} and front_door_ai… |
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. |
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 question tags alone cannot answer; or by kind… |
