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.
Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.
POST https://api.apiverve.com/v1/graphqlquery {
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 →
Frequently Asked Questions
How do I get an API key for Inflation Rate?
How many credits does Inflation Rate cost?
Each successful Inflation Rate 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 inflation rate lookups.
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?
What happens if I exceed my Inflation Rate credit limit?
