Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

First indexed and scored.

## MCP tools (3)

### `create_invoice` (~178 tokens)

Create a payment invoice and get a hosted checkout link to send to the payer. amount_fiat is in the MERCHANT's base currency (USD, EUR, COP, ARS, BRL or MXN — confirm which one before charging; the response's fiat_currency tells you). Invoices expire in 1 hour by default; pass expires_at (ISO 8601) for slow payers. Use reference to tag the invoice with your own order id or client name.

Input parameters:

- `amount_fiat` (number, required): Amount in the merchant's base currency
- `commerce_id` (string): Merchant id (defaults to VOULTI_COMMERCE_ID env)
- `expires_at` (string): ISO 8601 expiration (default: 1 hour from now)
- `reference` (string): Your own memo: order id, client name…

### `get_invoice` (~84 tokens)

Check an invoice's payment status. status: Pending → Paid | Expired. On Paid it includes paid_tx_hash (on-chain proof), payment_method and paid_at. Poll every few seconds while the payer is at checkout. Verify Paid here before releasing goods — even if you also receive a webhook.

Input parameters:

- `invoice_id` (string, required): Invoice id (data.id from create_invoice)

### `get_payment_link` (~72 tokens)

Get the merchant's PERMANENT payment page link, where the payer types the amount themselves. Never expires. Good for tips, donations or 'pay what you owe' — for fixed amounts prefer create_invoice.

Input parameters:

- `commerce_id` (string): Merchant id (defaults to VOULTI_COMMERCE_ID env)
