An API key is required; a free tier with limited requests per day is available. It is designed for developers building trading dashboards, currency converters, or financial applications that need live forex data.

Common Errors & Troubleshooting

401 Unauthorized Missing or invalid api_key query parameter

✓ Append ?api_key=YOUR_KEY to every request. Verify your key is active in the 1forge.com dashboard.

Currency pair not found Using incorrect pair format; pairs must be in the format XXXYYY without separators

✓ Use the format EURUSD or GBPJPY (6-character codes with no dash or slash). Check the /symbols endpoint for the full list.

Rate limit exceeded Exceeded the daily request quota on the free plan

✓ Cache the latest quotes on your server and throttle requests. Upgrade for higher daily limits.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
