# Start with a safe sample

This onboarding path is available now. It shows request and response syntax but does not issue a key, call a sandbox, make a payment, or execute a production request.

{% hint style="warning" %}
There is no verified sandbox key flow, isolated sandbox Base URL, or authorized production browser Test it. The host below is reserved and cannot be live.
{% endhint %}

## 1. Choose a service

Start with [Agentic Commerce Preflight](/signgate-api/api-reference/agentic-commerce.md), whose repository includes a credential-free sample representation.

## 2. View the sample request

```json
{"agent_role":"buyer","product_category":"api","amount_usdc":"0.025"}
```

## 3. Copy request syntax

{% tabs %}
{% tab title="cURL" %}

```bash
curl --fail-with-body -X POST 'https://api.example.invalid/v1/agentic-commerce/preflight' \
  -H 'Content-Type: application/json' \
  --data '{"agent_role":"buyer","product_category":"api","amount_usdc":"0.025"}'
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript
const response = await fetch("https://api.example.invalid/v1/agentic-commerce/preflight", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({ agent_role: "buyer", product_category: "api", amount_usdc: "0.025" })
});
console.log(await response.json());
```

{% endtab %}

{% tab title="Python" %}

```python
import json
from urllib.request import Request, urlopen

body = json.dumps({"agent_role": "buyer", "product_category": "api", "amount_usdc": "0.025"}).encode()
request = Request("https://api.example.invalid/v1/agentic-commerce/preflight", data=body, headers={"Content-Type": "application/json"}, method="POST")
with urlopen(request, timeout=10) as response:
    print(response.read().decode("utf-8"))
```

{% endtab %}
{% endtabs %}

## 4. Inspect the sample response

The sample preserves the service vocabulary: `ALLOW`, `REQUIRE_APPROVAL`, or `DENY`. It is a sample presentation, not proof of production availability.

## 5. Stop, approve, or continue

* `ALLOW`: continue only within the exact action and signer directive.
* `REQUIRE_APPROVAL`: pause and obtain an authorized approval through an approved flow.
* `DENY`: stop.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://123-87.gitbook.io/signgate-api/documentation/quickstart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
