GraphQL AccessALPHA

Access Currency Converter through GraphQL to combine it with other API calls in a single request. Query only the currency converter data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Currency Converter 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 {
  currencyconverter(
    input: {
      value: 1
      from: "USD"
      to: "EUR"
    }
  ) {
    from
    to
    value
    convertedValue
    rate
    change24h
    change24hPct
    changeDirection
    high24h
    low24h
  }
}

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

CORS Support

The Currency Converter 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

Currency Converter 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 Currency Converter 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 Currency Converter

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

No-Code Integrations

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

How many credits does Currency Converter cost?

Each successful Currency Converter 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 currency converter lookups.

Can I use Currency Converter in production?

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

When you reach your monthly credit limit, Currency Converter 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.
