# NewBotLabor Agent Preflight

> NewBotLabor Agent Preflight is a paid API for AI agents from newbotlabor--254ecdfcc2de11f19b541607ee4eb77e.web.val.run, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Inspects an x402-enabled endpoint URL to determine if it is payable, returning pricing, network, and compliance details before an agent commits funds.

## 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 newbotlabor-agent-preflight-5ab7c0e5
```

Example prompt: Before my agent pays for that API, preflight the x402 endpoint at https://example.com/api/data and confirm it's payable and costs under $0.05.

## When to prefer this

Use this endpoint when an AI agent needs to safely inspect an unknown or untrusted x402-gated API before committing USDC funds — especially to enforce budget caps, confirm canonical USDC on Base mainnet, and catch misconfigured payment headers before a real call is made. Prefer this over calling the target endpoint directly when cost or network compliance is uncertain.

## Known failure modes

- Target URL does not support x402 — returns isX402: false with an empty cheapestMainnetUsdc
- Target URL is unreachable or times out — may return an error or non-x402 verdict
- Price exceeds maxUsd threshold — verdict may indicate not payable within budget
- Malformed or missing url query parameter — request rejected with validation error
- x402 headers present but non-canonical USDC asset — assetIsCanonicalUSDC returns false with issues listed

## How this service works

Pay-per-call utilities for autonomous agents, paid with x402 (USDC on Base, or USDC/USDT on Celo; no account, no API key).

## Output

Returns a JSON object with: a boolean isX402 indicating x402 support, a verdict string (e.g. 'payable_ok'), the x402 protocol version, the cheapest mainnet USDC price with network ID and canonical asset flag, and an issues array listing any problems found with the endpoint's x402 configuration.
