## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability loophole-tape-launches-since-cursor-poll-0266a61a -d '<json body>'
```

Example prompt: Poll pump.fun for any new memecoin launches since my last cursor and give me each token's rug probability and graduation odds so my trading bot can decide which to act on.

## When to prefer this

Use this endpoint when operating a bot that continuously polls for new pump.fun token launches in an incremental, cursor-driven fashion. Prefer this over GET /v1/launches/recent (which covers only the last hour and is suited for one-off screens) when you need stateful, deduplicated streaming of launches over time without re-fetching old data. For analyzing a single known mint, use the dedicated rug check endpoint instead.

## Known failure modes

- Invalid or expired cursor returns an error or empty result set
- Rate limiting if polling too aggressively
- No new launches since cursor returns an empty array (not an error)
- Network timeout on Solana RPC backend causing delayed response
- Malformed cursor value causes a 400-level error

## How this service works

New pump.fun memecoin launches since a cursor, with rug probability and graduation odds ($0.001 per poll). Use when a bot polls for newly launched Solana tokens on pump.fun with their calibrated odds; for a one-off screen of the last hour use GET /v1/launches/recent, and for one mint the $0.005 rug check.

## Output

A paginated list of newly launched pump.fun memecoins since the provided cursor, each entry including token mint address, launch timestamp, calibrated rug probability score, and graduation odds. Also returns an updated cursor for the next poll call.
