From the project's README
As published by bobymicjohn/2b2tatlas-public-api in README.md.
Documentation and examples for the 2b2tAtlas public API: historical locations, groups, highways, Archive warps, world downloads, map renders, and Nocom observation aggregates.
Base URL: https://api.blackportal.cloud. Public reads require no API key.
JSON responses support browser CORS.

Requests
curl --fail "https://api.blackportal.cloud/api/locations"
curl --fail "https://api.blackportal.cloud/api/groups"
curl --fail "https://api.blackportal.cloud/api/renders?limit=10"
curl --fail "https://api.blackportal.cloud/api/nocom/highways?dimension=nether&direction=northeast"
List responses are JSON arrays. Warps, renders, and attachments accept limit
and offset; the default limit is 500 and the maximum is 1,000. Locations return
the complete catalog.
Examples
To run your own Atlas, see examples/atlas-stack. That folder is an Unlicense application snapshot. The smaller API clients below remain standalone examples for consuming the public service.
Run from the repository root:
dotnet run --project examples/csharp -- "Mu Megabase"
node examples/javascript/atlas-examples.mjs "Mu Megabase"
python examples/python/atlas_examples.py "Mu Megabase"
python examples/python/nocom_activity.py --dimension nether --direction northeast
python examples/python/location_media.py 1254
The C# example uses .NET 10. The JavaScript and Python examples use their standard
libraries. Each defaults to the public API; set ATLAS_API_BASE_URL to use a
local fixture or development server.
examples/requests.http contains REST Client requests. examples/fabric contains an asynchronous Java HTTP client and Minecraft client-thread handoff example; it is not a complete mod.
Endpoints
All routes below use GET. See the reference for response
fields, filters, caching, and errors.
| Resource | Routes |
|---|---|
| Locations | /api/locations, /api/locations/{id} |
| Groups | /api/groups, /api/groups/{id} |
| Highways | /api/highways, /api/highways/{id} |
| Archive warps | /api/warps, /api/warps/{id} |
| Warp WDL metadata and ZIP | /api/warps/{id}/world-download, /api/warps/{id}/world-download.zip |
| Renders | /api/renders, /api/renders/{id}, /api/locations/{id}/renders |
| Preserved render-source WDL metadata and ZIP | /api/renders/{id}/world-download, /api/renders/{id}/world-download.zip |
| Historical media | /api/attachments, /api/attachments/{id} |
| Map layers | /api/maprenders, /api/maprenders/catalog |
| Nocom | /api/nocom, /api/nocom/periods, /api/nocom/highways |
Client behavior
- Cache catalog responses and honor HTTP cache headers. In Minecraft clients, perform HTTP requests and image decoding outside the render/tick thread.
- Follow returned links such as
apiUrl,canonicalUrl,worldDownloadUrl, andblueMapUrl. BlueMap links are optional and belong to a specific render. - Handle null fields and ignore unknown JSON properties.
- Coordinates use the record's native dimension:
0Overworld,1Nether,2End. Tile-template{y}is a tile row, not Minecraft elevation. - WDLs are partial historical Java saves. Their metadata includes scope, provenance, size, and SHA-256; ZIP downloads support HTTP ranges.
- Historical coordinates and renders do not describe the current server state. Nocom observation counts are not unique-player counts.
- Retain source URLs, captions, attribution, and evidence fields when copying records so the original material can be checked.
MCP
Endpoint: https://api.blackportal.cloud/mcp. Transport: Streamable HTTP.
The server is stateless and read-only, with no authentication required.
The MCP guide includes client configuration, the 18 tools, and
resource URIs. The registry name is
io.github.bobymicjohn/2b2t-atlas;
its manifest is server.json.
Bulk data
Static exports are hosted on 2b2tatlas.com:
| File | Content |
|---|---|
| dataset.json | Dataset metadata and catalog links |
| locations.jsonl | Location records |
| groups.jsonl | Groups and relationships |
| media.jsonl | Historical media records |
| world-downloads.jsonl | Available partial WDLs, checksums, and source links |
| llms.txt | Data and documentation index |
Use these exports for bulk imports. Keep entity IDs and canonical URLs with imported records. The WDL catalog also has an HTML view.
Existing integration
XaeroTools supports an optional Atlas location overlay with source links and local copies of Atlas map imagery.
