## 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 overnight-memecoin-research-endpoint-73dc6d1d
```

Example prompt: What's the overnight sentiment and momentum outlook for PEPE — is there any notable trading signal I should know about going into tomorrow?

## When to prefer this

Choose this endpoint when you need AI-powered overnight research specifically on memecoins, including sentiment, momentum, and trading signals. Prefer this over general crypto APIs when the user wants qualitative AI analysis rather than raw price data, and when the target asset is a memecoin or low-cap meme token.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid or unrecognized memecoin ticker — may return empty or low-confidence result
- Malformed POST body — returns 400 Bad Request
- Service unavailable on Railway hosting — returns 502 or 503
- Rate limit exceeded — returns 429 Too Many Requests

## How this service works

Get tokens that moved significantly during off-hours (midnight to 8am UTC) with AI-generated analysis of what happened while you slept.

## Output

Returns an AI-generated research summary covering sentiment, momentum, and trading insights for the queried memecoin, including directional signals and relevant context gathered overnight.
