FAQ

▸How do I get started?
Install the CLI (npm i -g @clawcard/cli), sign up, create a key, and run clawcard setup. Your agent gets email, phone, card, wallet, and identity in about 2 minutes.
▸What agents does this work with?
Any agent that can read a skill file — Claude Code, Cursor, Gemini CLI, Codex, OpenClaw, and more. If your agent can make HTTP calls, it works.
▸How does the balance work?
You top up with a credit card ($5, $10, or $25). That balance covers everything — API calls from the catalog, virtual card creation, and on-chain payments. One balance, no complexity.
▸What is x402?
x402 is the open standard for paying APIs with stablecoins, developed by Coinbase. When your agent hits an API that requires payment (HTTP 402), the wallet pays automatically and gets the data back.
▸What is MPP?
MPP (Machine Payments Protocol) is a payment standard built by Stripe and Tempo for machine-to-machine transactions. Your agent pays with pathUSD stablecoins on the Tempo network. ClawCard auto-bridges your USDC to pathUSD, so you don't need to think about it.
▸What's the on-chain identity?
An ERC-8004 NFT on Base that proves your agent's identity — name, wallet address, capabilities. Other agents and services can verify who your agent is on-chain. It's like a passport for the agent economy.
▸How do the virtual cards work?
We issue virtual Mastercards with per-card spend limits. Choose single-use (auto-closes after one charge) or merchant-locked (reusable at the same vendor). Use cards for traditional checkouts, use the wallet for API payments.
▸What happens if my agent goes rogue?
Every card and wallet has hard budget limits. You can freeze the wallet, kill card creation, revoke individual cards, or delete the entire key. Every action is logged with a full audit trail.
▸Do I need to understand crypto?
No. You top up with a credit card, your agent spends from the balance. The on-chain wallet and stablecoin payments happen behind the scenes — you never touch private keys or sign anything.
▸How is this different from giving my agent my credit card?
Don't do that. ClawCard gives each agent an isolated identity with its own card numbers, wallet, spend limits, and audit trail. If something goes wrong, you revoke the agent — not your own card.
▸Is there a monthly fee?
No subscriptions, no monthly fees, no markup. Top up $5, $10, or $25 — your full balance is available for API calls and virtual cards. What you pay is what you get.
▸Is it free to get started?
Signing up is free. Your agent gets email, phone, stablecoin wallet, on-chain identity, and service discovery at no cost. Top up your balance when you need virtual cards or want to fund your stablecoin wallet.
