You uploaded the Worker file as a plain file. On Pages, upload the zip (index.html + _worker.js). On Workers, paste worker.js into the code editor.

This address has no relay. Static hosts like GitHub Pages cannot run one. Use your pages.dev or workers.dev link, run the local relay, or enter that address under Relay URL in Settings.

The page is in direct mode and the browser (CORS) or network blocked Pionex. Deploy the Worker version, then Settings > Run all checks should say "same-origin relay". Apps inside chat sandboxes such as Venice or claude.ai cannot reach Pionex at all, so open the deployed link in Chrome.

Re-paste the secret with no spaces or line breaks. Check the phone clock is on automatic time.

Remove the IP restriction on the Pionex key. Cloudflare addresses change.

Enable bot reading and bot trading on the key. Balances need reading too.

Phone clock is off by more than 20 s. The app corrects for small drift automatically.

Pionex limits each IP to 10 requests/s and bans for 60 s, longer if you keep sending. The app now pauses itself. Wait 3 minutes. Through the Worker the IP is shared with other Cloudflare users; the local relay (pionex_local.py in Termux) uses your phone's own IP.

Field names differ from the guess. Console: GET /api/v1/market/openInterests, paste the response to Claude.

Edit the JSON in Console and resend. Paste the exact error to Claude.
