# AGENT DATASTORE — append rows to your wallet's persistent storage

`POST /api/store/{collection}`

## Request

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

AGENT DATASTORE — append rows to your wallet's persistent storage. POST JSON (object or array) or CSV; rows append to the named collection owned by your paying wallet and persist across calls, deploys, and restarts. The wallet that pays IS the identity — no keys, no accounts. Give your agent a memory. Activity keeps it alive: reads extend the collection 30 days, writes 60. Limits: 16KB/row, 1000 rows/call, 100k rows/collection, 50 collections, 50MB/wallet.

Price: $0.02 per call, paid in USDC via the x402 protocol (see the x402 security scheme).
