## 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 orders-of-magnitude-stream-dedup-api-febea8fc
```

Example prompt: Can you deduplicate this stream of text for me and return only the unique entries: 'apple
banana
apple
orange
banana
grape'?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use deduplication of streamed text data without setting up your own infrastructure. It is well-suited for lightweight, one-off deduplication tasks where cost per call ($0.01 USDC) is acceptable and you want a real-time result over a micropayment channel using the x402 protocol.

## Known failure modes

- Missing required 'input' parameter returns a 400 or similar error
- Payment not provided or x402 payment fails resulting in a 402 Payment Required response
- Empty string input may return empty or trivial output
- Very large input strings may time out or be rejected
- Response schema is underspecified so output format may be unpredictable
