API and MCP server

Plug the national charging-station registry into your own systems and AI tools. The MCP server answers anyone in public mode; full records, the REST API, the change feed and webhooks come with Enterprise.

MCP server (AI tools)

Connect ChargeCensus to Claude, ChatGPT or your own agent. The server is https://chargecensus.com/api/mcp (Streamable HTTP). Without a key it answers in public mode: summaries with a link to each record, 5 results per call. With an Enterprise key it returns full records, change history and the change feed.

REST API (Enterprise)

Create a key under Account → API keys, then send it as Authorization: Bearer cck_live_…. JSON responses; keyset paging with cursor; up to 100 records per page and 120 requests a minute per key.

curl -H "Authorization: Bearer $KEY" \
  "https://chargecensus.com/api/v1/stations?state=TX&limit=100"
