Domain Availability Check AI Agent / LLM

Domain Intelligence and Analysis
POST /api/v1/domain/check Bearer

Everything an AI coding assistant needs to write a working Domain Availability Check integration without opening another page: endpoint, authentication, parameters, a real request, both response shapes and the platform rules it cannot infer from a single example. Copy the brief below and paste it into Claude, Cursor, GitHub Copilot, ChatGPT or any other agent.

# Domain Availability Check API — Way2API®

- **Endpoint:** `POST https://app.way2api.com/api/v1/domain/check`
- **Auth:** `Authorization: Bearer YOUR_API_KEY` (or `X-API-Key: YOUR_API_KEY`)
- **Content-Type:** `application/json`
- **Category:** Domain Intelligence and Analysis
- **Availability:** Available worldwide
- **Docs:** https://app.way2api.com/documentation/domain-availability-check-v1

## What it does

Domain Check API — Look up the registration status and availability of any domain name. Returns domain registration details including registrar, creation date, and expiration date. Useful for domain resellers, web hosting platforms, and brand protection services.

## Request body (application/json)

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `domain` | string | yes | Domain name to check (e.g. example.com) |

## Example request

```bash
curl -X POST https://app.way2api.com/api/v1/domain/check \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"example.com"}'
```

## Success response — 200

```json
{
    "status": "SUCCESS",
    "status_code": 200,
    "charged": true,
    "success": true,
    "message": "",
    "message_code": "OK",
    "order_id": "W2A1739512345abcdef01",
    "data": {
        "order_id": "W2A1739512345abcdef01",
        "result": {
            "domain": "example.com",
            "available": false,
            "registrar": "Example Registrar",
            "expires": "2027-01-01"
        }
    }
}
```

## Integration rules

- Every response is JSON carrying `status`, `status_code`, `charged`, `success`, `message`, `message_code` and (once a call reaches the provider) `order_id`. The verification payload is under `data.result`.
- `charged` (boolean) is the authority on billing. Do NOT infer it from the HTTP status: `422` is returned both for input we rejected (not charged) and for a lookup the provider ran and billed us for that returned a negative result (charged).
- `message_code` is a fixed vocabulary — branch on it instead of parsing `message`. Values: `OK`, `ACCEPTED`, `PROVIDER_NO_RESPONSE`, `VERIFICATION_FAILED`, `NO_RECORD_FOUND`, `INVALID_INPUT`, `REQUEST_FAILED`, `MISSING_API_KEY`, `INVALID_API_KEY`, `INSUFFICIENT_BALANCE`, `NO_API_ACCESS`, `NOT_FOUND`, `RATE_LIMITED`, `INTERNAL_ERROR`, `PROVIDER_UNAVAILABLE`.
- `success` reports the verification outcome; `status` reports the ORDER lifecycle (`SUCCESS`/`PENDING`/`FAILED`). They differ on a charged negative result: the order completed and was billed while the verification did not pass.
- A failed verification is still a successful HTTP call — the outcome lives in the response body, so do not treat `200` as "verified".
- Status codes: `200` result returned, `202` pending or provider did not respond (both charged — quote the `order_id`), `401` missing/invalid key, `402` insufficient balance, `403` no access to this service, `422` see `charged`, `429` rate limited (honour the `Retry-After` header), `503` temporarily unavailable.
- Rate limits are per API key, per service, on a 1-minute sliding window.
- Load the API key from an environment variable or secret store. Never hard-code it, never commit it, and never ship it in client-side code — calls must be made from your backend.

Prompts to pair it with

  • Write a production-ready Domain Availability Check integration in PHP using this spec, with error handling and retries.
  • Given this spec, generate typed request/response models and a client class.
  • Review my existing Domain Availability Check integration against this spec and list what I handle incorrectly.
⚠ Before you paste generated code

Never let an assistant hard-code your API key — load it from an environment variable or a secret store, and call this endpoint from your backend only. A failed verification is still a successful HTTP call, so check the success field in the body rather than treating 200 as verified.
