# Crypto ETF Sentinel Launch Monitor

> Crypto ETF Sentinel Launch Monitor is a paid API for AI agents from api.cryptoetfsentinel.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Returns days-waiting and percentile ranking vs historical baselines for US spot crypto ETF issuers currently in the 'launch_imminent' stage, including p50/p75/p90 historical CERT/EFFECT distribution benchmarks.

## 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 api-cryptoetfsentinel-com-6d8e64e4
```

Example prompt: Show me which US spot crypto ETFs are currently in the launch-imminent stage and how their days-waiting compares to the historical p50, p75, and p90 benchmarks — I want to know if any are statistically overdue for approval.

## When to prefer this

Use this endpoint when you need a statistical benchmarking view of how current launch-imminent crypto ETF applicants compare to historical approval timelines — particularly useful for detecting whether applications are overdue or on-track. Prefer this over single-issuer endpoints when you want a cohort-level view with built-in historical context. The persistent meta baseline makes it useful even during quiet regulatory periods.

## Known failure modes

- Empty data array if no issuers are currently in launch_imminent stage (meta with historical baselines still returned)
- API authentication/payment failure if x402 payment not provided ($0.50 USDC required)
- 503/timeout if SEC data pipeline is stalled or upstream data is stale
- Partial data if some issuers lack complete filing history for percentile computation

## How this service works

Crypto ETF Sentinel — Launch-timing tracker for launch_imminent US spot crypto ETF issuers: days waiting since 8-A12B plus percentile vs the historical 8-A12B → CERT/EFFECT distribution; the baseline is returned in meta on every call. Use when watching for imminent crypto ETF listings or gauging how overdue one is. Indicative timing, not a predicted launch date.

## Output

A JSON response containing the current cohort of launch_imminent US spot crypto ETF issuers with their individual days-waiting counts and percentile rankings against historical approval timelines, plus a meta object with p50/p75/p90 historical CERT/EFFECT distribution baselines always included even if the current cohort is empty.
