Public reference API · v1.0.0
Build with DeepScreen reference content
Retrieve exchange metadata, educational metric definitions and stock screening answers. These public GET endpoints require no API key and cannot trade, access accounts or retrieve personal data.
Endpoints
| GET endpoint | Returns |
|---|---|
| /api/v1/exchanges | Exchange code, name, country, currency and directory URL |
| /api/v1/metrics | Metric names, definitions, formulas, cautions and guide URLs |
| /api/v1/answers | Questions, answers, review date and reference URLs |
Example request
curl --fail https://deepscreen.online/api/v1/exchangesEach response includes version, resource, documentation, limitations and data. Answers also include reviewedAt, which is an editorial review date. No endpoint accepts query parameters or pagination. Cache responses for up to one hour. Handle errors and back off before retrying; never fill missing data with invented values.
Scope and attribution
This is educational reference content, not a live financial feed. It does not return quotes, company financial statements, forecasts, subscriptions or portfolio information. Link readers to the returned source URL and retain the cautions when quoting a definition. Do not send credentials or personal information to these endpoints.
Availability depends on the hosting service. There is no published service-level guarantee. Unsupported query parameters return 400; unknown resources return 404. Only GET is documented. Cross-origin GET requests are allowed.
