# Loophole Tape – Recent Robinhood Chain Launches

> Loophole Tape – Recent Robinhood Chain Launches is a paid API for AI agents from api.loopholetape.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a real-time list of recent token launches on Robinhood Chain (Pons V2) with risk metrics including buyer flow, concentration, and bonding-curve progress.

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-recent-robinhood-chain-launches-71dfdc78
```

Example prompt: Show me the last 20 Robinhood Chain token launches from the past 30 minutes that are still live on the bonding curve and have at least 10 buys, so I can screen them for sniper concentration.

## When to prefer this

Choose this endpoint when you need real-time, independently captured Robinhood Chain (Pons V2) launch analytics without needing an account or API key — especially useful for agent workflows that require pay-per-call pricing in USDC, want to screen multiple launches at once with filters for age, buy count, or live status, and care about holder concentration and sniper-cluster signals that third-party resold data often misses.

## Known failure modes

- Payment not sent or insufficient USDC — HTTP 402 returned before data
- Invalid query parameter types (e.g. non-integer limit) — likely 400 error
- max_age_s set to very short window with no matching launches — empty items array with count 0
- Coverage field returns 'partial' if internal event capture has gaps for a time window
- Network latency spike if chain indexing is catching up to the tip

## How this service works

Live pump.fun / PumpSwap risk checks and Robinhood Chain Pons V2 launch analytics, computed in real time from our own independent capture of every on-chain event (not resold third-party data). Pay per request in USDC on Solana or Base through x402: no account, no API key, 0.5-2.5 cents per call. Responses report coverage, freshness and observed evidence.

## Output

A JSON object with an 'ok' flag, a 'coverage' field ('full' or partial), and a 'data' object containing a count and an array of launch items. Each item includes: age in seconds, bonding curve address, ETH raised and curve progress percentage, current status (e.g. live_curve), buy flow stats (total buys, unique buyers), and holder structure metrics (top-1 share, terminal holdings share, same-block direct cluster share).
