Frequently Asked Questions

A single WebSocket URL that streams every Polymarket trade the moment it appears in the Polygon mempool — typically 1.5s before on-chain confirmation. You get both pending and confirmed events, with full trade details: wallet, counterparty, size, price, side, market role, and timestamps.

Two ways, your choice. In Python, pip install polyflux-client, drop in the API key we email you, and iterate typed trades in a few lines — with auto-reconnection handled for you. Prefer no dependency? Open a plain WebSocket to the URL we email you instead: no auth header, no polling, and the key is embedded in the URL path — so any language that speaks WebSocket works: Python, Node, Rust, Go, or even a browser. It's the same feed underneath.

The Regular plan allows 1 concurrent WebSocket connection. There's no limit on the number of trades you receive — you get the full firehose. If you need multiple connections or dedicated infrastructure, contact us for an Institutional plan.

Stripe automatically retries failed charges over a few days. During that window your key stays active. If all retries fail, your key is disabled until the balance is settled. No data is lost — just reconnect once your payment goes through.
