GET
cURL
Use Pre-game sides at /api/v1/sports/pre-game-sides in new clients. This older route remains available for existing integrations. Responses include Deprecation and Link headers that identify the replacement route.

Parameters

The route accepts the same parameters as Pre-game sides. The OpenAPI section below lists them.

Key response fields

The response data matches Pre-game sides. Both paths include side, ranked_at, backing_score, and side_share, along with the older piled_side, signal_created_at, conviction_score, and smart_score aliases.

What it does not return

This route adds no data beyond the replacement endpoint. Follow its documentation for field meanings, errors, pagination, and any caching behavior.

Authorizations

Authorization
string
header
required

Legacy default or named integration API key, or OAuth 2.1 access token, in the Authorization header as Bearer oxi_sk_live_... or Bearer oxi_at_.... Default keys retain full access; integration keys are limited to their approved read, webhooks, export and usage scopes and expire within 90 days. All credentials share the owner's account limits. Data calls require an active Pro subscription and return live data. A 401 carries WWW-Authenticate: Bearer resource_metadata="https://api.0xinsider.com/.well-known/oauth-protected-resource" (RFC 6750 section 3, RFC 9728).

Headers

X-Query-Validation
enum<string>

Opt into strict query-name validation. The default is compatible: unknown names are ignored and reported in X-Query-Ignored. With strict, an unknown name returns 400 bad_request with error.reason unknown_query_parameter before the handler runs, including when its percent escape is incomplete.

Available options:
strict
If-None-Match
string

Conditional GET validator from a previous ETag. Matching values return 304 Not Modified with an empty body.

Required range: 1 <= x <= 100
cursor
string
