GraphQL AccessALPHA

Access Inflation Rate through GraphQL to combine it with other API calls in a single request. Query only the inflation rate data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Inflation Rate 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 {
  inflation(
    input: {
      country: "US"
      year: 2023
    }
  ) {
    country
    countryName
    year
    inflationRate
    cpiIndex
    cpiBaseYear
    lastUpdated
  }
}

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

CORS Support

The Inflation Rate 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

Inflation Rate 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 Inflation Rate 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 Inflation Rate

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

No-Code Integrations

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

How many credits does Inflation Rate cost?

Can I use Inflation Rate in production?

The free plan is for testing and development only. For production use of Inflation Rate, 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 Inflation Rate from a browser?
Yes! The Inflation Rate 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 Inflation Rate credit limit?

When you reach your monthly credit limit, Inflation Rate 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.
