Response drift: probable — base URL in config returns 404; working URL is market-api.probable.markets

Severity

CRITICAL

What Our Normalizer Expects

core/src/exchanges/probable/config.ts sets api.probable.markets as the base URL for all public API calls (e.g. GET /public/api/v1/events/, GET /public/api/v1/markets/, GET /public/api/v1/book).

// config.ts (probable)
BASE_URL: 'https://api.probable.markets'

What The Live API Returns

https://api.probable.markets/public/api/v1/events/ returns HTTP 404 ("Resource not found") for all paths under /public/api/v1/. The working base URL is https://market-api.probable.markets:

GET https://api.probable.markets/public/api/v1/events/?limit=2  → 404 (broken)
GET https://market-api.probable.markets/public/api/v1/events/?limit=2  → 200 (working)

The working response shape from market-api.probable.markets is valid JSON with the expected market structure.

Impact

CRITICAL: Every API call from the probable adapter fails with a 404 error. fetchMarkets, fetchEvents, fetchOrderBook, and fetchTrades all return nothing. The exchange is completely non-functional as configured. Users see no probable markets.

Suggested Fix

Update the base URL in core/src/exchanges/probable/config.ts:

BASE_URL: 'https://market-api.probable.markets'

Then verify all endpoint paths still work correctly against the new base URL.
