Capital B
Company API endpoints for Bitcoin treasury, holdings, price, profile, and performance data.
Request format
curl -X GET "https://newhedge.io/api/v2/companies/capital-b/METRIC_NAME?api_token=YOUR_TOKEN"
api_token (required) — 24 character token.
:metric_name — one of the company metric names listed below.
200 with JSON payload, 401 for missing/invalid token, 404 for missing resources. A company removed from the dataset answers 404, with a successor field when its Bitcoin treasury is now tracked under another company, for example {"error":"Company not found","successor":"strive-asset-management"}. A renamed company keeps answering at its old slug.
Plan and quota refusals keep these statuses and error texts and add code, required_plan, current_plan, feature, upgrade_url, limit and resets_at where they apply. A Pro token whose history window removed points also gets the X-Newhedge-History-Truncated headers, and for a Pro token X-Newhedge-Available-From is the start of the window. See Errors and plan limits.
