pump.fun Callout Alerts for Trading Bots

Q: How do I monitor a pump.fun caller?

Add a pump.fun username, Solana wallet, or profile URL in the Callouts tab. TweetStream resolves the account and saves it to your Callouts list.

Q: How many pump.fun callers can I track?

Every plan can track up to 10 Callouts accounts, including additions that are still pending.

Q: What does a Callout event contain?

Each event includes the caller username and token address. Token name, symbol, artwork, URL, market cap, price fields, and the observed multiple appear when available.

Q: Is this the official pump.fun API?

No. TweetStream is independent from pump.fun and exposes its own customer WebSocket contract for selected caller monitoring.

What you get

Follow pump.fun callouts from up to 10 accounts. Add a caller by pump.fun username, Solana wallet, or profile URL, then receive each callout as an `account/callout` WebSocket event. The caller username and token address are always present. Token details, artwork, market cap, callout price, and multiple are included when available.

Use cases

Direct caller monitoring

Follow callers by their pump.fun identity instead of assuming every call will also appear on X.

Bot filtering

Send the token address, caller, and available market fields into your own filters and risk checks.

A readable caller list

Use optional labels for the names your desk recognizes while retaining the pump.fun username.

Trading workflow routing

Route qualifying Callouts to an internal dashboard, alert queue, or pre-trade review step.

How it works

Choose your callers - Add a pump.fun username, Solana wallet, or profile URL. Use an optional label when your team knows the caller by another name.
Receive structured callouts - Each observed call arrives as `account/callout` with `pump_fun` in the platform field and a stable event ID.
Score the call in your system - Apply your own liquidity, token, caller, and risk rules before routing the event into alerts or trading logic.
