Draft Fantasy developer resources

Public, read-only resources for agents and software integrations.

Quick start

Use the versioned product endpoint for stable, machine-readable links and capability information. It is public, requires no authentication, and does not expose private account or league data.

curl https://www.draftfantasy.com/api/v1/product

Machine-readable contracts

Errors and versioning

Errors under /api/v1 use RFC 9457 problem details with an application/problem+json content type, stable error codes, and recovery guidance. Stable operations use a major version in the URL. A breaking change will use a new major path; any retired version will be announced at least 90 days ahead and identified with Deprecation and Sunset response headers.

Game documentation

Player-facing rules for drafts, squads, scoring, waivers, trades, and league administration are published at docs.draftfantasy.com. Questions about a public integration can be sent to [email protected].
