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-daily-launch-dataset-abb7d9ac
```

Example prompt: Pull the full pump.fun launch dataset for September 11 2026 — I need the download link, row count, and checksum so I can verify and import it.

## When to prefer this

Use this endpoint when you need a complete, verifiable batch export of all pump.fun/PumpSwap token launches for a full calendar day — ideal for backtesting, ETL pipelines, historical audits, or offline analysis. Prefer this over the real-time or polling endpoints when you need bulk data with integrity guarantees (SHA-256) rather than live streaming or per-token checks.

## Known failure modes

- Day not yet available (future date or data still ingesting) — returns an error or empty result
- Invalid date format in path parameter — returns a 400-level error
- Dataset expired download token — URL valid only for 3600 seconds after issuance
- Payment failure via x402 — request blocked if USDC payment is not completed
- No data for very early historical dates before pump.fun launched

## 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

Returns a JSON object with a boolean ok flag, the requested day string, total row count, dataset size in bytes, a SHA-256 checksum for integrity verification, a time-limited download URL (expires in 3600 seconds), and a coverage field indicating whether the day's data is complete.
