SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Crow enables autonomous AI agents to pay for APIs and services when payments are required (e.g., 402 payments and subscription charges) without human intervention.

Core Features & Use Cases

  • Supports x402 USDC payments to cover API calls that return HTTP 402 Payment Required.
  • Supports credit-card payments via Stripe with auto-approve thresholds and human review when needed.
  • Provides status polling, settlement, and end-to-end flow for wallet setup, authorization, and settlement.
  • Use case: an agent calls a paid API and Crow handles payment automatically and replies with a signed payload or token.

Quick Start

When a 402 response is received, forward the full response to Crow and retry the original request with the signed payload.

FAQPage Schema
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?▼

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.
