Machine-readable specs + Postman collection. Codegen your own SDK, or import into any HTTP tool.

OpenAPI 3.1 (REST)

Complete REST specification — 18 endpoints across Discovery, Market Data, Account, Trading, Sandbox, Keys. Codegen with openapi-generator (50+ target languages).

Format	File	Size	Use
YAML	openapi.yaml	30 KB	Human-readable, easy diff
JSON	openapi.json	48 KB	Redoc / Swagger UI / codegen tools

AsyncAPI 2.6 (WebSocket)

Complete WebSocket specification — 48 event types (5 meta, 9 market data, 4 fast round, 6 signals/AI, 12 account private, 6 security, 8 ops public, 3 admin) + 4 client methods (SUBSCRIBE / UNSUBSCRIBE / AUTH / LOCALE).

Format	File	Size	Use

Postman Collection

Ready-to-import collection with all endpoints pre-configured. Includes 2 environments (sandbox + production) with placeholder variables — fill in your key and go.

File	Purpose	Size
postman.json	Collection — all 18 REST endpoints + example bodies	220 KB
pax-sandbox.postman_environment.json	Sandbox environment — `baseUrl`, `apiKey`, HMAC secrets	<1 KB
pax-production.postman_environment.json	Production environment — same structure, prod URLs	<1 KB

Import into Postman

Open Postman → Import (top-left).

Drag all 3 files (collection + 2 environments), or paste the URLs:

https://docs.predictasiax.com/downloads/postman.json
https://docs.predictasiax.com/downloads/pax-sandbox.postman_environment.json
https://docs.predictasiax.com/downloads/pax-production.postman_environment.json

Top-right environment selector → pick PAX Sandbox.
Environment tab → fill in apiKey = your sk_test_* key. Save.
Open any request → hit Send. Done.

Postman → cURL: After configuring a request in Postman, click the Code button (top-right of request panel) to copy the equivalent cURL, Python, Node, or Go snippet.

SDKs (coming)

Native SDKs are on the roadmap for v1.1 (Q4 2026). Meanwhile use openapi-generator (above) or hand-roll REST clients — the API is intentionally simple to consume without SDK.

Language	Package	Status
Python	`pax-api` (pypi.org, coming)	Q4 2026
TypeScript / JavaScript	`@predictasiax/api` (npmjs.com, coming)	Q4 2026
Go	Codegen only for now	2027
Rust	Codegen only for now	2027

Mock server (Prism)

Spin up a local mock server against the OpenAPI spec for offline development:

npm i -g @stoplight/prism-cli
prism mock https://docs.predictasiax.com/downloads/openapi.json
# → mock server on http://localhost:4010

Prism generates fake responses per the OpenAPI examples — great for CI or client development before sandbox access is provisioned.
