Read-only discovery over the APIs.io catalog, with guided prompts for every job. NEW HERE? Call get_playground_apis first — a curated set of APIs that need no key and cost nothing, each with a working example request you can call immediately to get a feel for calling APIs safely. Then start with apis_io_search, or a prompt: find_api / provider_overview / integrate_provider to discover and adopt; improve_my_score / agent_readiness_scan / claim_and_improve to raise a provider you own; state_of_report / movers_briefing / insights_landscape for data stories; design_api_stack / audit_api_estate / benchmark_against_peers to decide. Discovery is free; the ratings, synthesis, and demand depth are Pro — prompts list everything and upsell on use.

Inferred read-onlyget_cohortOne cohort: its identity, its population, and the full member roster with each provider's Kin Score and agent readiness.
Inferred read-onlyget_tag_groupOne tag group: its member tags and the full provider roster resolved from the catalog, each with Kin Score and agent readiness.
Inferred read-onlytag_group_tagsThe member tags of one tag group, each joined to its catalog record — provider count, api count, tag quality band and composite.
Inferred read-onlycohort_statsBUSINESS — 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.
Inferred read-onlycohort_rankingsBUSINESS — the leaderboard for a market, on TWO axes: rank by Kin Score composite AND rank by agent readiness.
Inferred read-onlycohort_scoresBUSINESS — facet-level scores for every member of a cohort, each with the cohort average and the delta against it.
Inferred read-onlycohort_capabilitiesBUSINESS — what every member of a cohort actually publishes: artifact counts by type plus the agent-readiness dimensions each one satisfies.
Inferred read-onlycompare_cohortsBUSINESS — two markets side by side on one rubric: "is US payments further along than UK banking?
Inferred read-onlyget_provider_operationsEvery operation a provider exposes, across all of its OpenAPIs — method, path, operationId, summary, which API it belongs to, and whether it is deprecated.
Inferred read-onlyget_provider_toolsEvery MCP tool a provider ships, with the operation each one wraps and its auth.
Inferred read-onlyget_provider_schemaEvery JSON Schema a provider publishes — the data shapes their API works in, in one list, without walking their artifacts.
Inferred read-onlyget_provider_facetsPRO — one provider's score broken into its facets (discoverability, contract quality, governance, operational transparency, developer ergonomics, commercial clarity) plus any regulatory regime that applies.
Inferred read-onlyget_agent_readinessFREE — 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…).
Inferred read-onlyfind_agent_readinessPRO — the agent-readiness leaderboard across the whole catalog.
Inferred read-onlyagent_readiness_dimensionsPRO — diffusion: for each agent-readiness dimension, how many scored providers satisfy it, out of how many, as a share.
Inferred read-onlyget_capabilityOne business capability: its definition, its sub-capabilities, the external authorities it cites, and WHICH catalog providers reach it with their ratings.
Inferred read-onlyget_provider_business_capabilitiesPRO — what ONE vendor's published APIs let a business DO, rolled up by capability, with the tag-level evidence under each.
Inferred read-onlyget_provider_capabilitiesWhat one provider publishes, counted by artifact type, with the agent dimensions it satisfies.
Inferred read-onlyget_provider_evidenceHow 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).
Inferred read-onlyget_rating_rubricThe rubric — bands, facet weights, trend thresholds — so an agent can interpret any score.
Inferred read-onlyfind_artifactsFind artifacts of ANY one type across the catalog — the cross-type entry point.
Inferred read-onlycompare_providersBUSINESS — Compare 2+ providers side by side: composite/band, per-facet leaders, and an artifact-coverage matrix.
Inferred read-onlygap_analysisBUSINESS — 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.
Potential side effectswhats_changedPRO — 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` and `compared_to` on every row.
Inferred read-onlyrecommend_stackDesign an API stack — the best-rated catalog provider per capability, assembled into a stack.
Inferred read-onlyget_provider_artifactsEvery 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.
Inferred read-onlyget_api_artifactsOne 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.
Inferred read-onlyget_openapiAn API's primary OpenAPI reference (url) — the top agent intent; set include=["content"] to inline the spec body.
Inferred read-onlyget_provider_onboardingA getting-started view for a provider — website, portal, signup, docs, authentication, base URLs, and first steps assembled from its registered links.
Inferred read-onlyfind_similar_providersProviders similar to a given one (alternatives) by shared tags, industry, region, and artifact coverage.
Inferred read-onlyget_rating_historyPRO — A provider's REAL score time series: one point per scored build (composite + agent readiness on each date), plus a summary of the movement over the window — first/last, net change, direction, and the largest single-build jump with the date it happened.
Inferred read-onlyfind_rating_moversPRO — The biggest rating movers (up and down) since the previous scoring build.
Inferred read-onlystory_leadsOWNER — 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.

Inferred read-onlyexport_datasetBUSINESS/license tier — 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 arrays across every scored build the catalog retains, with a movement summary per provider).
Inferred read-onlyindustry_gap_analysisBUSINESS — Valuable artifact types (MCP, Arazzo, Rules, Skills…) commonly missing across a whole industry — where the vertical is under-served.

Inferred read-onlylist_saved_searchesPRO — List the saved searches you own (name, criteria, when last run, how many matches are tracked).
Inferred read-onlyrun_saved_searchPRO — Re-run one of your saved searches against the live catalog and return current matching providers.
Inferred read-onlysaved_search_net_newPRO — What is NEW for a saved search since you last checked: providers that newly match your criteria.

Inferred read-onlyreport_correctionReport that the catalog has a provider WRONG — a wrong website, a wrong logo, APIs that are not theirs, a count that does not match what they ship, a score computed from any of those.
