# Telnyx Toolkit

The complete toolkit for building with Telnyx. Includes **ready-to-use tools** and **SDK documentation** for all Telnyx APIs.

## Quick Start

```bash
export TELNYX_API_KEY="your_key_here"
```

---

## 🚀 Getting Started

Two companion skills handle account lifecycle. They are included with the toolkit and can also be installed independently via ClawHub.

| Skill | Purpose | Path | Install standalone |
|-------|---------|------|--------------------|
| **Telnyx Bot Signup** | Create a new account or sign into an existing one (PoW challenge → email → API key) | `{baseDir}/getting-started/telnyx-bot-signup/` | `clawhub install telnyx-bot-signup` |
| **Telnyx Freemium Upgrade** | Upgrade freemium → professional via GitHub or LinkedIn identity verification | `{baseDir}/getting-started/telnyx-freemium-upgrade/` | `clawhub install telnyx-freemium-upgrade` |

### When to Use Account Signup

Hand off to **telnyx-bot-signup** when ANY of these are true:

- No API key exists (`TELNYX_API_KEY` not set, `~/.config/telnyx/config.json` missing)
- API key is invalid/expired (401 errors from Telnyx API)
- User wants to create a new Telnyx account
- API key needs to be refreshed after an upgrade (same email, new key)

> **Note:** The `bot_signup` endpoint handles both new and existing accounts transparently — just provide the user's email.

### When to Use Account Upgrade

Hand off to **telnyx-freemium-upgrade** when ANY of these are true:

| Trigger | Detection |
|---------|-----------|
| Error `10039` | SMS send fails: "destination not verified" |
| Error `D60` | Voice call fails: "destination not verified" |
| Error `10038` | Feature blocked: "not available on current plan" |
| Number limit hit | Second phone number purchase fails |
| Cannot add funds | Freemium account cannot add payment method or top up |
| Explicit request | User says "upgrade my account" |

Before handing off, check `~/.telnyx/upgrade.json` — if `decision` is `APPROVED`, the account is already upgraded (retry the operation instead). If `PASS_TO_HUMAN`, it's under review (don't retry). See the telnyx-freemium-upgrade SKILL.md for full decision tree.

Each skill has its own `SKILL.md` with complete instructions. Read the skill's SKILL.md before executing its workflow.

## 💳 Balance & Payments

Use these endpoints to check balance and add funds programmatically.

> **Important:** Top-ups charge the payment method (credit card, PayPal, or ACH) saved in the [Telnyx Portal](https://portal.telnyx.com). There is no API to add a payment method — this is done by the user in the portal. Do not prompt the user about this upfront — just attempt the top-up when needed. If it returns 403, that's when you inform the user they need to add a payment method in the portal.

### Check Balance

```bash
curl -s https://api.telnyx.com/v2/balance -H "Authorization: Bearer $TELNYX_API_KEY"
```

**Response:**
```json
{
  "data": {
    "balance": "300.00",
    "credit_limit": "100.00",
    "available_credit": "400.00",
    "currency": "USD"
  }
}
```

### Check Auto-Recharge Status

Check whether auto-recharge is enabled. If it is, the account will top up automatically when balance drops below the threshold — the agent can just wait and retry instead of manually topping up.

```bash
curl -s https://api.telnyx.com/v2/payment/auto_recharge_prefs -H "Authorization: Bearer $TELNYX_API_KEY"
```

**Response:**
```json
{
  "data": {
    "enabled": true,
    "threshold_amount": "100.00",
    "recharge_amount": "100.00",
    "preference": "credit_paypal"
  }
}
```

If `enabled` is `true` and the agent hits `20100`, wait briefly and retry — auto-recharge should handle it. If `enabled` is `false`, proceed with the top-up endpoint below.

> **Note:** Enabling or configuring auto-recharge is a human decision — use the [Telnyx Portal](https://portal.telnyx.com) to change these settings.

### Add Funds (Top Up)

Charges the stored payment method on file. Requires a payment method already configured in the Telnyx Portal.

```bash
curl -s -X POST https://api.telnyx.com/v2/payment/stored_payment_transactions -H "Authorization: Bearer $TELNYX_API_KEY" -H "Content-Type: application/json" -d '{"amount": "100.00"}'
```

The `amount` field is in dollars and cents (e.g., `"100.00"`, `"25.50"`).

**Response:**
```json
{
  "data": {
    "id": "de06811a-2e43-4561-af5a-7d0a26e20aaa",
    "record_type": "transaction",
    "amount_cents": 10000,
    "processor_status": "submitted_for_settlement",
    "amount_currency": "USD",
    "created_at": "2026-02-25T10:00:00Z",
    "auto_recharge": false
  }
}
```

**Error handling:**

| Status | Meaning | Action |
|--------|---------|--------|
| 200 | Transaction submitted | Wait for settlement, then retry the original operation |
| 401 | Unauthorized | API key is invalid — hand off to telnyx-bot-signup |
| 403 | Forbidden | No stored payment method on file — direct user to [Telnyx Portal](https://portal.telnyx.com) to add one |
| 422 | Invalid amount | Amount must be a string with dollars and cents (e.g., `"120.00"`) |

### Payment Error Decision Tree

When a Telnyx API call fails with a payment-related error, follow this tree. The agent does not need to know the account tier upfront — the error codes and response codes reveal the right path.

**Step 1: Identify the error**

| Error Code | Meaning | Go to |
|-----------|---------|-------|
| `10038` / `10039` | Feature not permitted / limited | Step 2 (upgrade) |
| `20100` / `20012` | Insufficient Funds / Account inactive | Step 3 (try top-up) |

> **Note:** The API may return `20100` (Insufficient Funds) even on freemium accounts where `10038`/`10039` would be more accurate. Don't assume `20100` means the account is professional — always attempt the top-up and let the response tell you.

**Step 2: Feature restriction → Upgrade first**

Errors `10038`/`10039` mean the account is freemium. Freemium accounts cannot add payment methods or top up — they must upgrade first.

1. Hand off to **telnyx-freemium-upgrade** → upgrade to professional
2. User adds payment method at [Telnyx Portal](https://portal.telnyx.com)
3. Then proceed to Step 3 if funds are needed

**Step 3: Insufficient funds → Try to top up**

Always attempt the top-up regardless of account tier — the response will reveal the right path.

1. `GET /v2/balance` — check current available credit
2. `GET /v2/payment/auto_recharge_prefs` — if `enabled: true`, wait briefly and retry (auto-recharge will handle it). If it does, stop here
3. If auto-recharge is off: `POST /v2/payment/stored_payment_transactions` — top up via API
4. **If top-up returns 200** → retry the original operation
5. **If top-up returns 403** → no payment method on file. This is the real signal:
   - Check `~/.telnyx/upgrade.json` — if `decision` is `APPROVED`, the account is professional but has no payment method → direct user to [Telnyx Portal](https://portal.telnyx.com) to add one
   - Otherwise, the account is likely freemium → hand off to **telnyx-freemium-upgrade** (Step 2)
