# Onchain Risk Checks – Memecoin Watch & Alert Engine

## 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 onchain-risk-checks-memecoin-watch-alert-engine-715bce97 -d '<json body>'
```

Example prompt: Set up a memecoin watch that re-runs my strategy every 15 minutes and posts an alert to my webhook at https://hooks.myapp.com/meme whenever a new matching token appears.

## When to prefer this

Choose this endpoint when you need continuous, automated monitoring of memecoin conditions — either to catch new tokens matching a filter strategy or to know when a held position should be exited — with push delivery to a webhook, Telegram, or Discord rather than polling manually. Prefer it over one-shot token scanners when you want ongoing surveillance without re-calling an API yourself.

## Known failure modes

- Invalid interval value returns an error (only 1m/5m/15m/30m/1h/4h/1d accepted)
- Invalid or unreachable webhook URL causes delivery failures silently
- Missing required 'type' field (strategy or position) results in a schema error
- Malformed strategy or position object may produce no alerts without clear error feedback
- Telegram bot token or chat ID misconfiguration causes notification delivery failure
- Payment failure ($0.05 USDC not received) blocks watch creation

## How this service works

Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.

## Output

Returns a watch ID that can be used to read alerts for free. The engine re-evaluates the provided strategy or position object on the configured interval (1m–1d) and pushes matching events to the specified webhook, Telegram chat, or Discord channel. Alerts include details on newly matched tokens or position exit signals.
