Sleeper Picks API providers: research notes
Provider research only: we do not supply Sleeper data. What Sleeper's official API covers, who claims Sleeper Picks lines, and what to test.
Editorial review: · Not a live coverage report
This page is provider research. This site does not supply Sleeper data and has no relationship with Sleeper or the providers listed.
What Sleeper's official API covers
Sleeper publishes a read-only API with no token and asks callers to stay under 1,000 calls per minute. It covers leagues, rosters, drafts, players and trending players. It mentions draft picks and traded picks, but we found no pick'em lines, projections or odds in it source. It serves fantasy league tools rather than Picks line data.
Who claims Sleeper Picks coverage
Competitor facts are paraphrased from the linked pages as they read on 2026-11-03 and may have changed. Treat vendor claims as claims: we have not measured them. This site is not affiliated with any company named here.
| Provider | What it publicly claims | Source |
|---|---|---|
| OpticOdds | Sleeper as a sportsbook ID. Sales-led access | source |
| ParlayAPI | sleeper as a DFS bookmaker key, with a measured row count dated 2026-09-05 | source |
| Betstamp | A Sleeper odds page claiming "sub-second refresh" and an SLA | source |
| SportsGameOdds | Lists Sleeper under daily fantasy coverage | source |
| Apify actor (zen-studio) | A scraper rather than a data licensor | source |
The Odds API's us_dfs list, as we read it, included Dabble, Pick6 and Underdog, with no Sleeper entry source. OpticOdds has a Sleeper page source, which we saw only as a search excerpt. This list is what we found on one date, not a full market map, and inclusion is not an endorsement.
What to test in a Sleeper Picks feed
Check these on real rows before you commit to a provider.
- Whether rows come from a Sleeper-specific capture, and how the provider labels the source.
- How multipliers are represented, and what happens to a line when it is pulled.
- When the provider captured a row, compared with when it says the source changed.
- History for one sport and stat you can check by hand.
- Rights for your use, especially for anything public. A claimed feed does not settle whether you may republish it.
