CRA AGENT runs on your own machine — the client starts it, so there is no endpoint to ping. 534 installs a week from npm. Last commit 22 Sep 2026.
Lets an agent pay for x402 APIs in USDC on Arc, under a spending policy it cannot change.
Today is the operative word: we check CRA AGENT every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
CRA_NETWORK (arc (mainnet) or arcTestnet), CRA_KEY_FILE (Path to a chmod 600 file holding the agent's private key. Never put the key in a prompt.), CRA_POLICY (Spending limits, e.g. daily=5,per_seller=0.5,per_payment=0.05), CRA_RPC_URL (Optional RPC endpoints, comma separated, in priority order), DATABASE_URL (Optional Postgres for the ledger; in memory without it).
The author declared them in the registry entry; get the values from the project itself.
