ParlayAPI in Postman

Postman

Import > Link, and paste:

https://parlay-api.com/collections/ParlayAPI.postman_collection.json

Importing by link rather than by file means a re-import picks up our latest version. Import > File works too if you would rather pin the copy you downloaded.

Insomnia, Bruno, HTTPie, Hoppscotch

All of them read Postman Collection v2.1, so the same URL or the same downloaded file imports directly.

Every endpoint, not just the curated set

The full auto-generated dump of the whole API surface lives at /collections/postman.json, built from /openapi.json on every deploy. It is the right import for code generation. This curated one is the right import for deciding whether the API does what you need.

Folder	Requests	What you get
1. Getting started	7, keyless	The /v1/try/* demo endpoints (odds, arbitrage, positive EV, middles), the sport and bookmaker catalogues, and the public line-movement feed. Real production data, no key.
2. Odds	7	Moneyline, spreads and totals across every book; the event list and single-event odds; best line per outcome; arbitrage and positive EV boards; line movement history.
3. Player props	3	Props for a whole sport grouped one row per prop, props for a single player, and the list of prop markets live for that sport.
4. Historical and closing lines	5	Archive coverage (keyless), point-in-time snapshots, closing odds over a date range, recent closing lines, and CLV grading for a bet slip.
5. Prediction markets	4	Kalshi and Polymarket by sport, crypto price ladders, and two keyless ones: keyword search across venues, and the books-vs-markets divergence feed.
6. Meta and status	4	Platform status, the per-endpoint credit cost catalogue, the discovery document, and your own usage and quota.

Set these once under Collection > Variables. Changing sport_key re-points most of the collection.

Variable	Default	What it is
base_url	https://parlay-api.com	API host. Leave it alone unless you are on the high-volume host.
api_key	(empty)	Your key, sent as the X-API-Key header. Empty on purpose: folder 1 runs without one.
sport_key	americanfootball_nfl	Any key from GET /v1/sports: 90+ of them.
event_id	an NFL Week 1 game	Refresh it from the Upcoming events request when it goes stale.
player	Patrick Mahomes	Partial name match for the props search.
asset	BTC	Asset for the crypto prediction markets.
date	a recent date	YYYY-MM-DD for the historical requests.

The free tier is 1,000 credits a month with no credit card. Sign up, copy the key into the api_key variable, and folders 2 through 6 start working.

Credits are charged per endpoint, and the odds endpoints scale with how many markets and regions you ask for, so it pays to ask for what you need. The full catalogue is GET /v1/meta/credit-costs and the tier table is on /pricing.

Streaming (WebSocket and SSE) is a Business-tier and up feature and is not in this collection, because Postman is not a streaming client. The streaming contract is described in /v1/asyncapi.json.

The odds response shape is drop-in compatible with their /v4 endpoints, so an existing Postman environment usually only needs the base URL and the key swapped. See the side-by-side comparison for what does and does not map across.
