Public Endpoints

Public endpoints return data without authentication.

Gateway

Unlike the Private API, the Public API routes through a single gateway. Each path prefix maps to the same host:

There is no single gateway. Each path prefix maps to its own service:

Path prefix	Host
/api/coins	https://wallet-mutator-view.outpoll.com
/api/events/*	https://event-service.outpoll.com
/api/categories	https://event-service.outpoll.com
/api/tags/*	https://event-service.outpoll.com

Use HTTPS for every request.

This host serves every public REST endpoint in this section.

Authentication

No authentication required.

Sections

• Public API Overview for the shared quickstart, errors, and pagination rules.

• Search Events for market discovery and filtering.

• Get Available Coins for supported assets and collateral metadata.

• Get Categories for category filters and navigation.

• Get Popular Tags for trending discovery tags.

Example requests

Use the gateway directly for both GET and POST endpoints.

Search events

curl -X POST "https://outpoll.com/api/events/search?page=0&size=20" \
  -H "Content-Type: application/json" \
  --data '{"sb":"VOLUME_24H","sd":"DESC","l":"en","ss":"bitcoin"}'

Pagination

Only Search Events is paginated.
