Find API endpoints, required parameters, response schemas, access tiers, and authentication details.

ChartExchange API v1 reference with endpoint groups, authentication, and access-tier guidance — The API v1 reference lists the current endpoints, parameters, response schemas, and required tiers.

Choose an endpoint

The API reference groups the available endpoints by data type. Each operation shows its HTTP method, path, parameters, response schema, and required API tier.

Expand an endpoint and read its parameter descriptions. Check the required symbol format, dates, ordering, pagination, units, and nullable fields for that endpoint.

Expanded API v1 endpoint showing parameters, tier requirement, and response schema — The expanded endpoint shows its required parameters, optional controls, response schema, and access tier.

Authenticate requests

API requests require a key, and each endpoint states its required tier. Plan & Billing shows the key and tier for an active API subscription. Send the key in the documented api_key query parameter.

The interactive reference automatically authorizes the key for a signed-in account. Keep the key in server-side configuration. Do not commit it, publish it in browser code, or include it in screenshots and logs.

Plan and Billing API Key panel with reveal, copy, tier, and API reference link — Plan & Billing shows the masked key, its tier, and controls to reveal or copy it.

Send a test request

Enter the required parameters and select Execute. The reference shows the request URL, status code, response headers, and response body. Start with a small date range or page, then add pagination and rate-limit handling to the caller.
