## 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 via-api-compare-0fae3727 -d '<json body>'
```

Example prompt: Can you compare PDF text extraction APIs for me and recommend the best one — I'm building in the US and need results in English?

## When to prefer this

Use this endpoint when an AI agent or user needs to quickly discover and compare APIs or software services by describing their need in plain language, without having to manually research options. Ideal for agentic workflows where the agent must programmatically select the best tool or service for a subtask. Prefer this over generic web search when you want a structured recommendation with alternatives, especially within commerce, services, information, or travel markets.

## Known failure modes

- Intent string too short or missing — validation error returned
- Invalid country code format (must be two uppercase letters) — 400 error
- Payment failure via x402 protocol — endpoint returns 402 Payment Required
- No suitable match found for the intent — empty or null recommendation
- Unsupported language or market enum value — validation error
