How do AI agents handle HTTP 402 Payment Required responses autonomously?▼

AI agents handle HTTP 402 Payment Required responses by using autonomous payment Skills that intercept the error, authorize USDC funds, and return a signed payload for the agent to retry the original request.

How do I set up a USDC wallet for autonomous agent payments on Base mainnet?▼

You can set up a USDC wallet for autonomous agent payments on Base mainnet by forwarding the 402 response to the payment coordinator, which calls the /setup endpoint to initialize the wallet and enforce default spending rules.

Does Crow support credit card payments via Stripe for API subscriptions?▼

Yes, this Skill supports credit card payments via Stripe for API subscriptions, utilizing auto-approve thresholds for automated transactions and triggering human review when charges exceed the configured limits.

What is the x402 payment protocol for AI agents?▼

The x402 payment protocol is a standard for AI agents to cover API calls returning HTTP 402 Payment Required, enabling them to autonomously sign payloads and settle USDC transactions without human intervention.

Can I enforce spending limits on autonomous AI agent crypto transactions?▼

You can enforce spending limits on autonomous AI agent crypto transactions by configuring default spending rules and auto-approve thresholds, which dictate when payments are settled automatically or require human review.

How does payment settlement polling work for autonomous agent API calls?▼

Payment settlement polling works by continuously checking the /authorize/status endpoint after an agent initiates a transaction, confirming when the USDC or card-based payment is fully settled and ready for the merchant.
