The x402 ecosystem page is becoming a live market map for agent-paid APIs.
This radar reads public Coinbase x402 pull requests and separates partner listings, MCP payment endpoints, mainnet rails, discovery metadata, and browser/payment-header launch signals. The useful question is not whether a launch mentions x402. It is whether agents can discover the paid surface, understand the cap, receive a proper 402, and reconcile the receipt.
Adds **Fabler Labs** under **Services/Endpoints**: a live, machine-payable x402 storefront for AI agents. It offers utility APIs (secret scanning, agent-config auditing, code-diff security auditing, and Open Graph image rendering) plus digital-product downloads, paid in USDC on Base with no account or API key.
Rows are public launch or implementation signals, not vulnerability findings. Use them to choose where a no-payment proof pass would add the most trust.
