# Paxie RH Burst History

> Paxie RH Burst History is a paid API for AI agents from api.paxie.fun, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Returns scored Robinhood Chain buyer burst events from the last 1–24 hours, each annotated with 30-minute outcome metrics (return, peak return, exit-rule returns) net of 2% round-trip costs.

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 paxie-rh-burst-history-ee1501f7
```

Example prompt: Pull the scored Robinhood Chain burst history for the last 12 hours, main tier only, so I can see how each burst performed at 30 minutes and under different exit rules after accounting for 2% round-trip costs.

## When to prefer this

Use this endpoint when you need historical scored burst data specifically for Robinhood Chain with outcome labels (30-min return, peak, exit rules) for backtesting or strategy evaluation. Prefer it over the real-time burst endpoint when you want post-hoc performance data rather than live signals, and over the Solana pump.fun burst history endpoint when your focus is on RH chain rather than Solana.

## Known failure modes

- Invalid hours value outside 1–24 range returns a validation error
- Unknown tier enum value causes a 400 bad request
- No bursts found in the specified window returns an empty array
- Payment not included or insufficient results in a 402 Payment Required response
- Server-side data pipeline lag may cause stale or incomplete recent data

## How this service works

Scored Robinhood Chain buyer bursts from the last 1-24 hours. Each row has its rug check and 30-minute outcome: return at 30 min, peak, the return under each exit rule (2% round-trip costs included) and whether the liquidity was pulled. Outcome fields are labels, not features (see /v1/fields). Data rewritten every 20 s (<= 30 s behind the chain); data older than 120 s is refused with a 503 and not charged.

## Output

A list of scored burst events on Robinhood Chain from the requested look-back window, each containing the burst's score, tier, 30-minute return, peak return, and return under various exit rules — all adjusted for 2% round-trip transaction costs.
