# YOUR SCRATCHPAD — a persistent memory file for notes to your future self

`POST /api/scratchpad/{name}`

## Request

- Base URL: `https://api.webbersites.com`
- URL: `https://api.webbersites.com/api/scratchpad/{name}`
- Auth: API key in header `X-PAYMENT`

YOUR SCRATCHPAD — a persistent memory file for notes to your future self. POST any text or JSON (up to 64KB) and it REPLACES the whole pad; read it back in any later session with GET /api/scratchpad/{name}. The paying wallet is the identity — no accounts, no keys. Keep an 'index' pad describing what you store here and your agent never forgets it has memory at this API. Reads extend a pad 30 days, writes 60. 50 pads per wallet.

Price: $0.005 per call, paid in USDC via the x402 protocol (see the x402 security scheme).

- `name` string, required

## Request body
