## 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 scriptmasterlabs-user-agent-parse-api-07e889a2
```

Example prompt: Can you parse this user-agent string — 'Mozilla/5.0 (iPhone; CPU iPhone OS 16_0 like Mac OS X) AppleWebKit/605.1.15' — and tell me what browser, OS, and device type it represents?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call user-agent parsing service with no subscription overhead, settled in USDC via x402 on Base. Ideal for AI agents or pipelines that process user-agent strings occasionally or at variable volume and want micropayment billing without API key management. Prefer alternatives if you need very high-volume batch parsing or require SLA guarantees beyond what a Render-hosted service offers.

## Known failure modes

- Missing or empty user-agent input returns an empty or error response
- Malformed or spoofed user-agent strings may result in unknown/null fields
- x402 payment failure (insufficient USDC balance) returns a 402 Payment Required response and no data
- Render cold-start latency may cause occasional timeouts on first call
- Highly custom or non-standard user-agent strings may not be recognized and return partial results

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns structured metadata extracted from the user-agent string, including browser name, browser version, operating system, device type (mobile/desktop/tablet), and platform details. Response is a JSON object with parsed fields derived from the input user-agent.
