Documentation enhancements (no API behavior changes):
- POST /sapi/v1/w3w/wallet/prediction/trade/batch-cancel: removed the unused per-item cancelInfoList[i].vendor field (server auto-fills predict_fun). Added Known Issues section covering the bracket-encoding incompatibility with mainstream HTTP libraries (Python requests, Java URI, Go net/url, Node url) — request returns -1022 Signature for this request is not valid because clients percent-encode [/] while the server signs over raw bytes; included Python / Java / Go workarounds.
- POST /sapi/v1/w3w/wallet/prediction/transfer/inbound: added explicit warning that the endpoint requires SAS authorization (returns -31003 if SAS is not enabled).
- POST /sapi/v1/w3w/wallet/prediction/trade/get-quote: documented the MARKET order minimum (amountIn ≥ ~1.5 USDT, varies by market depth; LIMIT orders are not subject to this minimum).
- GET /sapi/v1/w3w/wallet/prediction/transfer/status: corrected the response example — the success terminal state is COMPLETED, not SUCCESS. Added the full set of status values (COMPLETED, FAILED, PROCESSING, PENDING).
