exchangerate.devFree includes 5,000 requests a month, up to 10 requests a minute, all 10,296 currency pairs, live rates delayed by 15 minutes and the last 30 days of daily history. The data endpoints also work without a key, with limits of 10 requests a minute and 100 an hour per IP address.
What's included in Free
A free key gives your app a monthly quota of its own, instead of sharing a per-IP limit with others on the same network. All plans, including Free, include all 10,296 pairs and the MCP server. ECB daily fixes have no delay. You can display rates commercially on Free if you place a visible linked credit near them.

Calling without a key
The data endpoints work without a key. These calls use Free plan data rules and count toward a per-IP limit. If your server shares an IP address, it may reach the hourly cap sooner than you expect. Send Authorization: Bearer YOUR_KEY from your server to count calls against your account's quota.
| Keyless (no API key) | Limit |
|---|---|
| Requests per minute, per IP | 10 |
| Requests per hour, per IP | 100 |
| Data | Free plan rules |
When you reach a limit
If you exceed a limit, the API returns 429, a JSON body identifying the limit and a Retry-After header. Requesting a date outside your plan's history returns 403 with plan_gated, the earliest date available to you and the plans that include the requested date.
