## 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 crypto-technicals-x402-ai-summarize-74515447 -d '<json body>'
```

Example prompt: Summarize this article for me in bullet-point style, keeping it under 120 words: https://www.coindesk.com/markets/2024/01/15/bitcoin-etf-approval/

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call text summarization with flexible output styles (bullets, paragraph, TL;DR) and accept USDC/x402 micropayments. It is hosted on a VPS with crypto-native billing, making it suitable for AI agent pipelines that already use x402 payment flows. Prefer it over general LLM summarization when you need a dedicated, billable summarization microservice that returns structured JSON with word count metadata.

## Known failure modes

- URL is inaccessible or returns non-200 status — endpoint may return an error or empty summary
- Text input is too long and exceeds processing limits — truncation or error response
- Invalid style enum value — defaults or errors depending on implementation
- Payment not included or insufficient USDC — x402 402 Payment Required response
- maxWords set to an extremely low value — summary may be incomplete or truncated awkwardly

## How this service works

Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.

## Output

Returns a JSON object containing the generated summary text, the word count of the summary, and the source URL (if a URL was provided as input). The summary reflects the requested style (bullets, paragraph, or TL;DR) and respects the maxWords limit.
