BaanScope API and open data

Everything BaanScope publishes is readable by machines as well as people. There is no API key, no sign-up and no quota beyond ordinary fair use. This page is the index; the OpenAPI document below is the authoritative description.

OpenAPI 3.1

https://baanscope.com/openapi.json

Endpoints

Path	operationId	Summary
/data/{file}	getDataset	Download one aggregated dataset as CSV or JSON
/api/fx	getFxRates	Current THB reference exchange rates
/md/{path}	getPageMarkdown	Markdown representation of any page
/openapi.json	getOpenApiDocument	This document
/llms.txt	getLlmsTxt	Site overview for language models

Every page as markdown

Send `Accept: text/markdown` to any URL on this site and you get clean markdown back instead of HTML — the same content, without navigation, scripts or styling. The identical document is also served at /md/<path> if you would rather use a plain URL than negotiate. Responses carry `Vary: Accept`, so caches keep the two representations apart.

curl -H "Accept: text/markdown" https://baanscope.com/projects

Bulk datasets

Pre-aggregated cuts of the tracked pipeline, published as CSV and JSON under CC BY 4.0 with attribution the only condition. Cross-origin fetch is allowed, so notebooks and browser charts can read them directly.

Bangkok off-plan pipeline by district .csv .json
