Betstamp is a pro odds screen built for human bettors; FanLine Wire is a data feed built for code. Both carry FanDuel prices. The difference is the consumer — your eyes or your model.
| FanLine Wire | Betstamp | |
|---|---|---|
| Product shape | Feed API — JSON in, JSON out | PRO odds screen for bettors + sportsbook API |
| Primary consumer | Your code — models, bots, alerters | Humans at a screen; API for trading desks at last check |
| Delivery | Push WebSocket (AppSync) + REST discovery | REST pull + SSE stream at last check |
| Book coverage | FanDuel only, by design | FanDuel among 200+ books at last check |
| Market status pushes | OPEN ↔ SUSPENDED live | Not at tick level at last check |
| Free tier | Yes — free key, no card | Trial via demo request at last check |
| Test with zero signup | Yes — public demo snapshot | Requires signup at last check |

If you are a bettor — not a builder — Betstamp's value is the screen itself: normalized lines across 200+ books at last check, best-line views, and bet tracking. FanLine Wire has no interface to look at, by design. A person who reads prices should use a screen.
If your program makes the decisions — a model, a bot, an alerter, a spreadsheet filler — you need structured prices, not a UI to screenshot. FanLine Wire returns the full tick as JSON: price, status, selection, both odds formats, timestamped. Push WebSocket means the tick arrives when FanDuel moves, not when your poller wakes up.
One line to prove it's live — public demo, no key:

FanLine Wire is the better tool when code is the consumer: a screen your bot can't parse is dead weight. Pick by who — or what — reads the data. If you need the sharp-book reference alongside FanDuel prices, our sibling feed PinnWire covers Pinnacle the same way.
Partly. Betstamp's main product is a pro odds screen for bettors; it also sells sportsbook API access with REST and SSE delivery at last check, aimed at trading desks. If you need a screen, that is its strength; if you need a code-first feed, that is FanLine Wire's.
Yes — FanDuel appears among the 200+ books Betstamp normalizes at last check, and Betstamp runs dedicated FanDuel odds pages. FanLine Wire carries FanDuel exclusively: the whole feed is that one book.
Push beats polling for time-sensitive consumption: a polled REST loop sees a move on its next cycle, while a pushed WebSocket tick arrives as the book moves it. Compare the mechanics on the push vs polling page.
Betstamp's API pricing is quote-based at last check (demo request). FanLine Wire is self-serve: free key at launch, $29/mo paid entry, $149/mo scale tier. Different buyers entirely — screens for humans, feeds for code.
