# Loophole Tape RHC Curve Endpoint

> Loophole Tape RHC Curve Endpoint is a paid API for AI agents from api.loopholetape.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns real-time bonding curve analytics and risk metrics for a Robinhood Chain Pons V2 token launch, computed from independent on-chain event capture.

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-rhc-curve-endpoint-e23e42c6
```

Example prompt: Check the live bonding curve stats for this Robinhood Chain Pons V2 launch — I want to see ETH raised, curve progress, buyer count, and whether the top holder is concentrated.

## When to prefer this

Use this endpoint when you need independent, real-time on-chain bonding curve analytics for Robinhood Chain Pons V2 launches — particularly when assessing holder concentration, sniping risk, or launch momentum without relying on resold third-party data. Prefer it over generic DEX screeners when you need raw structural metrics like same-block cluster share or terminal holdings share that indicate manipulation risk.

## Known failure modes

- Unknown or invalid curve address returns error or empty data
- Token not yet indexed if very recently launched — coverage may be partial
- Network outage on Solana/Base may delay event capture, reducing data freshness
- Payment failure over x402 (insufficient USDC balance) blocks the request
- Curve address already graduated from bonding curve may return stale or limited data

## 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 containing: bonding curve status (e.g. live_curve), buy/sell flow (n_buys, n_sells, unique_buyers, new_buyers_last_6s), ETH raised and bonding curve progress percentage, price multiple vs launch, holder structure metrics (n_holders, top1_share, direct_buy_share, terminal_holdings_share, same_block_direct_cluster_share), and a coverage field indicating data completeness and freshness.
