## How do you make a real request?

This example calls [Google SERP API](/apis/google-serp-api/) using its documented input. Save the API key from the signup email, confirm your email and set FASTAF\_API\_KEY in your server environment.

```
curl --fail-with-body -H "Authorization: Bearer $FASTAF_API_KEY" 'https://api.fastaf.co/v1/serp?query=best+espresso+machine+for+home&country=us&language=en'
```

```
# pip install fastaf-sdk
import os
from fastaf import FastAF

with FastAF(os.environ["FASTAF_API_KEY"]) as client:
    data = client.request("serp", {"query":"best espresso machine for home","country":"us","language":"en"})
    print(data)
```

Google SERP JSON. organic\_results contains ranked title, link and snippet fields; search\_information describes the query. Other Google result blocks may also appear.

The example costs 5 credits after the trial. Alternatively, this endpoint costs $0.003 per successful x402 call at the default configuration; FastAF x402 calls start at $0.003. These are separate billing modes.

For x402, request the same parameters under `/x402/v1/serp` without an API key, validate the live PAYMENT-REQUIRED challenge, then sign and retry with a payment-aware client. A bare curl request returns HTTP 402 and does not pay; unsupported higher-cost options require API-key billing.

## Frequently asked questions

### What do these guides cover?

Practical workflows for search, commerce, news, jobs and page content.

### Are the examples production data?

No. Examples show request syntax and documented behavior; live results vary and must be validated for your task.

### How much does the example cost?

The API-key example uses 5 credits per successful call after the trial. This endpoint has a default x402 price of $0.003 per successful call in USDC on Base; the live payment challenge is authoritative.

### Does the SDK automatically pay an HTTP 402?

No. The API-key SDK does not sign wallet payments; x402 requires an explicitly configured payment-aware client and a funded wallet.
