Headers

Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →

GraphQL AccessALPHA

Access Air Quality through GraphQL to combine it with other API calls in a single request. Query only the air quality data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Air Quality in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  airquality(
    input: {
      city: "San Francisco"
    }
  ) {
    pm2_5
    pm10
    carbonMonoxide
    ozone
    nitrogenDioxide
    sulfurdioxide
    usEpaIndex
    gbDefraIndex
    recommendation
    city
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Air Quality API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Air Quality requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Air Quality API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →

SDKs for Air Quality

Official Air Quality packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →

No-Code Integrations

Air Quality works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →

Frequently Asked Questions

Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for Air Quality and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
How many credits does Air Quality cost?

Each successful Air Quality API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful air quality lookups.

Can I use Air Quality in production?

The free plan is for testing and development only. For production use of Air Quality, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.

Can I use Air Quality from a browser?
Yes! The Air Quality API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.
What happens if I exceed my Air Quality credit limit?

When you reach your monthly credit limit, Air Quality API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
