Air Quality Programmatic APIs

Air Quality Programmatic APIs provide real-time and forecast air quality data from 11,000+ monitoring stations in 1,000+ cities worldwide. APIs deliver Air Quality Index (AQI) measurements for PM2.5, PM10, NO2, CO, SO2, and ozone pollutants. Provided by AQICN (World Air Quality Index project) in partnership with the US EPA and global environmental agencies. Data is available via JSON API and map tile API for visualization.

Air Quality Programmatic APIs publishes 2 API contracts indexed on the APIs.io network: Air Quality Programmatic APIs Real Time Air Quality Tile API and Stations API. Tagged areas include Air Quality, Environment, EPA, Open Data, and Public Health.

The Air Quality Programmatic APIs catalog on APIs.io includes 1 JSON-LD context and 3 Spectral governance rulesets.

Air Quality Programmatic APIs’ developer surface includes engineering blog, authentication, FAQ, developer portal, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Open Data Portals (CKAN / DCAT)	covered	9.6 (thin)	-	-
Raycast Store Extensions (first-party publishers + community-wrapped products)	covered	9.6 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
