# Agent Preflight — API Discovery

> Agent Preflight — API Discovery is a paid API for AI agents from preflight.lorensaisolutions.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Inspects a given URL to detect API documentation, determine page type, assess automation difficulty, and recommend the best integration method for AI agents.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent-preflight-api-discovery-090d9126
```

Example prompt: Can you check whether https://api.example.com/docs has any API documentation I can use, and tell me the best way to integrate with it — I'm planning to use it for research purposes?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically determine whether a target URL exposes an API, how best to integrate with it, and how difficult automation would be — especially before investing resources in scraping or integration. Prefer this over generic HTTP HEAD checks or manual inspection when you need structured intelligence about API discoverability and integration strategy.

## Known failure modes

- URL is unreachable — reachable field returns false, no further analysis available
- Invalid or malformed URL input — schema validation error before request is made
- Target site returns non-standard response that reduces confidence score
- Rate limiting or network timeout on the target URL causing incomplete analysis
- CAPTCHA or bot-detection on target URL may limit depth of analysis

## How this service works

Paid URL analysis, CAPTCHA and login detection, API discovery, product intelligence, change monitoring, and batch preflight for AI agents and agent swarms.

## Output

Returns a JSON object indicating whether API documentation was detected at the URL, the recommended integration method (e.g. 'use_api_or_fetch'), page type classification, reachability status, automation difficulty rating, presence of structured data, risk flags, action links, a confidence score, latency in milliseconds, and a unique request ID.
