| Free tier | 2,500 geocoding requests a day (forward or reverse, one location per request), a hard limit that resets at 24:00 UTC, at 1 request per second; spreadsheet uploads up to 100 rows; one API key; no credit card unit requests; metered on request-count; every request counts, including bad requests and requests with no result. The cheapest paid steps are a one-time plan of 10,000 requests for EUR 20, usable for up to a year, and the X-Small subscription of 10,000 requests a day at 15 requests a second for EUR 45 a month. Geosearch (autosuggest) has no free amount. |

| Limits | - volume-quota (binding) 2,500 requests a day on the free trial, a hard limit reset at 24:00 UTC; past it the API answers HTTP 402 quota exceeded source
- request-rate 1 request per second on the free trial; faster answers HTTP 429 source
- per-object-cap one location per request; spreadsheet uploads up to 100 rows on the free trial source
unverified: the X-RateLimit-Limit header of a live free trial key was not read, since it needs a free trial account; the API page documents it as the total requests the account is limited to over 24 hours for free trials, and its example shows 2500 |
|---|
| Binding | volume-quota 1 request a second allows far more than 2,500 requests in a day, so the daily hard limit is met first |
|---|
| Identity | email the signup form asks for a name, a company or organization name, an email and a password, behind hCaptcha, or a Google or GitHub sign-up; no credit card for the free trial; the general terms set a minimum age of 18 |
|---|
| Egress | not applicable: a query API metered in requests, not bytes |
|---|
| Per-object cap | one location per API request: the API takes no batch; a spreadsheet upload on the free trial is limited to 100 rows, each row counted as one request |
|---|
| Retention | uploaded spreadsheets are deleted after 3 days for free trial users |
|---|
| Interface | rest HTTPS GET to api.opencagedata.com/geocode/v1/json (also xml and geojson) with the key in the key parameter; a request without a key answers HTTP 401 missing API key, and the documented test key answers HTTP 200; responses to free trial and one-time plan keys carry the quota in a rate element and in the X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset headers, which subscription responses do not carry |
|---|
| Tooling | any HTTP client; vendor tutorials for Node.js, PHP, Python and Ruby include parallel request scripts, and a command line tool geocodes CSV files |
|---|
| Composes with | 2,500 storable geocodes a day with no card, so a slow job of about 2,500 addresses a day can build a permanent table; a one-off batch beyond that is the EUR 20 one-time plan of 10,000 requests, or the Geoapify free plan (data-apis/geoapify) at 3,000 a day with a batch endpoint. Bulk path: no bulk path; one location per request and no data download |
|---|
| Reliability | past the daily hard limit the API answers HTTP 402, and a free trial key that keeps requesting past it is disabled with HTTP 403; free trial accounts are deleted after three months of inactivity, and accounts detected as several free trials of one user are fed randomly wrong results |
|---|
| Notes | Bulk path: no bulk path; one location per request, spreadsheet uploads of 100 rows on the free trial, and no data download. The vendor labels the free amount a trial for testing; it has no end date. |
|---|
| Evidence note | documented the pricing page (in its markdown form), the API reference, the FAQ, the signup form and the terms were quoted on 2026-10-30 and 2026-10-31; a keyless request answered HTTP 401 and the published test key answered HTTP 200 with zero results. No account was opened, so the 2,500 a day was not exercised; a keyed run to the 402 would move it to measured. |
