## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `check_payment_flow`

- The name "check_payment_flow" says "payment": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Verifies an agent's x402 payment flow against a free Base Sepolia testnet endpoint. Call with no arguments first to get back the payment-required challenge (price, network, payTo). Sign it with your x402 client, then call again passing paymentSignature as the encoded PAYMENT-SIGNATURE header value to get back a verified/failed receipt.
```
