# apis.directory

> The register of the API economy: the whole economy decomposed into grammar-nameable categories — industry verticals at NAICS grain and the functions every company runs — resolved through three levels: capability (the abstract resource), offering (capability × provider, where price and score live), provider.

QUALITY TIERS: tier 0 = listed; tier 1 = probed — mechanical checks recorded with probeScore 0–6; tier 2 = api.qa-verified with a public verdict URL.

FAMILY: apis.directory, api.qa, and apis.ax are one family — api.qa verifies, apis.ax offers, apis.directory registers.

## Machine faces

- [Register manifest JSON](https://apis.directory/index.json) — full denominators + 49 stable shard URLs (/index/{n}.json) carrying every offering
- [Agent card](https://apis.directory/agents.json)
- [Derived taxonomy JSON](https://apis.directory/taxonomy.json) — full NAICS 2022 industry axis (2,125 nodes), 13 APQC-bound functions, 636 capability clusters, definition types, coverage denominators
- Per capability: https://apis.directory/capability/{capability}.json
- Per offering: https://apis.directory/apis/{provider}/{product}.json
- Per provider: https://apis.directory/provider/{provider}.json
- Search: https://apis.directory/search?q={query}

## Deep taxonomy (derived, reproducible; basis stated per record)

- Industry axis: full NAICS 2022 — 2,125 nodes, browsable at https://apis.directory/industries/ (drill to national-industry depth; providers placed at their deepest confident node, inferred; 14,282 providers unmapped)
- Function axis: 13 functions bound 1:1 to APQC PCF 7.4 categories with level-2 process groups — https://apis.directory/functions/
- Capability clusters: 636 clusters over the full catalog (O*NET IWA work activities, APQC processes, UNSPSC service families, register-row seeds) — https://apis.directory/clusters/
- The overlay grid: verticals × functions composed, one click to each cell's provider list — https://apis.directory/ (cells at /grid/{vertical}/{function}/)

## The act graph (37 verbs × 124 nouns, curated catalog)

Every capability is a verb applied to a noun. Noun door: https://apis.directory/nouns/ (each noun page indexes everything that acts on it — schema.org potentialAction, with /noun/{noun}.json faces). Verb door: https://apis.directory/acts/ (the same graph in reverse). Offerings carry economicClass — INFORM (data) / RESOLVE (reads) / EFFECT (does) / COMMIT (books) / RETAIN (runs); inferred classes are flagged with their basis.
