# Changelog

> Index of the TerraLab docs for agents: [llms.txt](https://terra-lab.ai/docs/llms.txt). Every docs page is also served as markdown: add .md to its URL.

Changes to the MCP server and the REST API, newest first. Additive changes keep older clients working; anything that breaks a client is announced here first.

## 2026-10-27

- Developer documentation published at [terra-lab.ai/docs](https://terra-lab.ai/docs), with a markdown copy of every page and [/docs/llms.txt](https://terra-lab.ai/docs/llms.txt).
- Tool descriptions state the `radius_m` limits of `get_satellite_image`, so agents get a valid call on the first try.
- `HEAD` works on `/v1/openapi.json` and `/v1/meta/pricing`, for link checkers.

## 2026-10-26

- Out of free calls or balance, the `402` answer points to the account page in `account_url`.

## 2026-10-25

- New price grid: 100 calls included every month, then 5 per 1,000 calls and 0.05 per satellite image, from a prepaid balance. No subscription. See [Pricing](https://terra-lab.ai/docs/pricing).
- A call that fails or finds nothing is no longer counted.
- `GET /v1/me` returns the exact balance in `balance.micros`.
- `GET /v1/meta/pricing` publishes the grid as JSON.
- `get_natural_risks` reads a weekly mirror of the Géorisques files.

## 2026-10-24

- TerraLab accounts on the MCP server, with OAuth 2.1 sign-in for agents and `tlk_` API keys for code.
- REST API at `https://mcp.terra-lab.ai/v1`, with an [OpenAPI 3.1 document](https://mcp.terra-lab.ai/v1/openapi.json).
- New tools: `find_datasets`, `extract_dataset`, `request_data`, `estimate_population`, `get_forest_type` and `get_natural_risks`.
- Sentinel-2 images are cached 90 days by area, scene and rendering.

## 2026-10-23

- New tools: `get_route`, `get_travel_area`, `process_geometry` and `get_satellite_image`.
- `extract_open_data` accepts `geopackage` as a format.

## 2026-10-19

- TerraLab app live in ChatGPT.
- `get_elevation` area mode returns DEM, hillshade and slope GeoTIFFs for any area.
- Every open data extract also offers a GeoPackage.
