**C · 61.7/100 · rank #360 of 722 · #5 in Weather & climate data · not agent-ready · confidence medium**


Assessment: Eight of the APIs publish OpenAPI 3.1 specs, and the Forecast API spec lists the credit cost of every package. A public Pingdom page shows monthly uptime per API. The key travels only in the query string, the free trial covers nine forecast packages, and no security.txt, certification or DPA was found.

- Endpoint: `https://my.meteoblue.com` (HTTP)
- Auth: API key · pricing: Freemium · x402: no · licence: Proprietary service under meteoblue's general terms and conditions. The Python SDK for the Dataset API is MIT
- Probe metrics: not measured yet (probes haven't run)
- APIs: Forecast (`/packages/...`), History (`/history/point`), Accounting (`/account/usage`) and Model-Run Archive (`/archive/run/point`) at https://my.meteoblue.com, Warnings at warnings-api.meteoblue.com, Measurements at measurements-api.meteoblue.com, plus Dataset, Image, Maps, Climate Data and Location Search APIs
- Forecast packages: 54 paths in the spec. Basic, current, clouds, sun and moon, agro, solar, PV, wind, sea, air, air quality, trend (14 days), ensemble, multimodel, seasonal anomaly, nowcast (6 hours at 5-minute steps), risk and raw model packages
- Free Weather API: 10 million credits valid for one year. Agro, air, air quality, basic, clouds, PVPro, solar, trend and wind packages at hourly, 3-hourly, 6-hourly or daily steps, plus meteogram images. The comparison table puts this at about 1,000 to 5,000 calls and marks commercial use as allowed
- Forecast range: 7 days in the basic package, 14 days in the trend packages, 6 months of monthly anomalies in the seasonal package, and up to 4 past days with `historyDays`
- History: From 1940, one variable per call, at most 30 years per call, hourly, daily or monthly, 27 variables. Charged at 100 credits per hour of data, 50 per day when aggregated daily and 25 when monthly. Not in the free trial
- Credits per call: `current`, `basic-day` and `sunmoon` 4,000. `basic-1h`, `sea-1h` and `airquality-1h` 8,000. `wind-1h`, `solar-1h`, `trend-1h` and `multimodel-1h` 16,000. `trendpro-1h` and `seasonalanomaly-monthly` 32,000. Raw model packages 96,000
- Rate limits: 500 calls a minute unless agreed otherwise, plus daily credit limits per account and per key. A request over the daily limit returns an error
- Errors: 400, 401, 403, 404 and 429 with a JSON body of `error: true` and an `error_message` string. A call with no key returned 400 in our check
- Formats: JSON by default, CSV, XLSX and Highcharts for forecasts. JSON or CSV for history. Units for temperature, wind and precipitation are query parameters
- Premium Weather API price: EUR 2,400 a year for 40,000 calls a month at about 8,000 credits a call, as shown on the pricing page. Tiers of 150,000 and 500,000 calls a month carry 400 and 800 in the page markup against 200 for the first tier, which we read as euros a month. Larger volumes by request
- Key controls: Several named keys per account, each with a daily limit, deletable in the Weather API Manager. Optional shared secret for HMAC-SHA256 signed URLs with `expire`, a referrer and origin allow list, and an IP allow list

## Before you call it

1. Pass `lat`, `lon` and `apikey` to `https://my.meteoblue.com/packages/<package>`. Join packages with commas, such as `basic-1h,basic-day`, to get several in one call
2. Budget credits before calling. One call costs 4,000 to 96,000 credits by package, and the free trial holds 10 million for a year. Read `MB-Credits-Accounted` on each response
3. Set `forecastDays` and pick the coarsest resolution that does the job. Without it the API returns every forecast day it has
4. Call with a 30-second timeout, wait 30 seconds after an error and stop after 10 retries, as the availability page advises. The default limit is 500 calls a minute
5. Keep the key out of logs, since it is part of every URL. Ask for a shared secret and send `expire` and `sig` if URLs may be seen by others

## Connect

```bash
pip install meteoblue-dataset-sdk
```

```bash
curl "https://my.meteoblue.com/packages/basic-1h?lat=47.5596&lon=7.5886&tz=utc&apikey=YOUR_APIKEY"
```
