# VATlayer

Operate **VATlayer** through your OOMOL-connected account. This skill calls the `vatlayer` connector with the [oo CLI](https://github.com/oomol-lab/oo-cli); OOMOL injects credentials server-side, so you never handle raw tokens.

Category: Finance, Data & Analytics. Exposes 5 action(s).

## Running an action

Assume the user has already installed the oo CLI, signed in, and connected VATlayer. **Do not run `oo auth login` or open the connection URL proactively — just run the action.** Fall back to [First-time setup](#first-time-setup) only when a command actually fails with an auth or connection error.

**1. Inspect the contract** to get the authoritative input/output schema before building a payload:

```bash
oo connector schema "vatlayer" --action "<action_name>"
```

**2. Run the action** with a JSON payload that matches the input schema:

```bash
oo connector run "vatlayer" --action "<action_name>" --data '<json>' --json
```

- `--data` takes a JSON object string or `@path/to/file.json`; omit it to send `{}`.
- The response is `{ "data": ..., "meta": { "executionId": "..." } }`; the execution id lives under `meta.executionId`.

Each action below links to a reference file with its purpose and exact commands. Read the linked file, then fetch the live schema with `oo connector schema` before constructing `--data`.

## Available actions

- [`calculate_price`](actions/calculate_price.md) — Calculate VAT-compliant inclusive and exclusive prices with vatlayer.
- [`get_rate`](actions/get_rate.md) — Retrieve VAT rates for one country selected by country code, IP address, or client IP.
- [`list_rates`](actions/list_rates.md) — Retrieve VAT rates for all EU member states from vatlayer.
- [`list_types`](actions/list_types.md) — List vatlayer reduced VAT rate type identifiers for price calculations.
- [`validate_vat_number`](actions/validate_vat_number.md) — Validate a VAT number and return company information when vatlayer finds it.

## Safety

- Read actions (get / list / search) are safe to run directly.
- **Create, update, send, or post actions change VATlayer state — confirm the exact payload and effect with the user before running.**
- **Delete or remove actions are destructive — always confirm the target and get explicit approval first.**

## First-time setup

These are **one-time** steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

- **`oo: command not found`** — install the oo CLI (other platforms: <https://cli.oomol.com/install-guide.md>):

  ```bash
  curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux
  ```

  ```powershell
  irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell
  ```

- **Not signed in / authentication error** — sign in to your OOMOL account once:

  ```bash
  oo auth login
  ```

- **`scope_missing` / `credential_expired` / `app_not_ready` / `app_not_found`** — VATlayer is not connected, or the connection expired or lacks a scope. Connect once (auth type: API key) at:

  ```text
  https://console.oomol.com/app-connections?provider=vatlayer
  ```

- **HTTP 402 / `OOMOL_INSUFFICIENT_CREDIT`** — billing stop. Recharge at `https://console.oomol.com/billing/token-recharge` before retrying.
