Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-pump-fun-new-launch-feed-since-cursor-e0532ac7
```

Example prompt: Poll pump.fun for any new memecoin launches since cursor 1717200000, return up to 50 tokens, and only include ones with a graduation probability above 0.05.

## When to prefer this

Use this endpoint when you need to continuously poll for new pump.fun token launches in a bot or automated pipeline, especially when you want calibrated rug probability and graduation odds attached to each token. For a one-off look at the last hour use GET /v1/launches/recent instead; for a per-mint deep rug check use the dedicated $0.005 rug check endpoint. This endpoint is optimized for cursor-based incremental polling at $0.001 per call.

## Known failure modes

- Missing or invalid 'since' cursor returns malformed response or empty data
- Cursor far in the past may return very large result sets; use 'limit' to cap
- Invalid 'min_p_grad' value outside 0–1 range may cause a 400 error
- Network or payment failure (x402) causes request to not proceed
- Rate limiting if polling too aggressively without adequate delay between calls

## How this service works

New Solana tokens as they launch on pump.fun: a cursor feed of new memecoin launches 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 memecoin mints since the provided cursor, each with a calibrated rug probability score, graduation odds, and coverage metadata indicating how fresh the data is. The response includes an 'ok' status, a 'data' array of token records, and a 'coverage' object.
