# Purchase Airtime

POST https://api.vtuagent.com/v1/airtime/purchase
Content-Type: application/json

Purchase airtime for a Nigerian mobile number.

Your wallet is debited **immediately** and the purchase is queued to the network provider. The request then long-polls for up to **15 seconds** for the provider's result. If the provider has not answered by then you receive `202` with `status: "pending"` — the transaction is still in flight, not lost. Track it with `POST /v1/transaction/status` or via your webhook.

| HTTP | `status` | `status_code` | Meaning |
|---|---|---|---|
| 200 | `successful` | 200 | Airtime delivered |
| 202 | `pending` | 202 | Still processing after 15 s |
| 400 | `error` | — | Bad payload, validation failure, insufficient balance, or duplicate `request_ref` |
| 401 | — | — | Missing, invalid or revoked API key |
| 424 | `failed` | 424 | Provider rejected the purchase — wallet already refunded |
| 500 | `error` | — | Internal error; wallet is rolled back |

**Webhook events:** `airtime.purchase.success`, `airtime.purchase.failed`, `airtime.purchase.pending`.
