Show HN: X402 integrations for an AI-agent data API, checked in a clean room

Blockchain IQ reports that 20 of 22 bounty claims for x402 integrations passed its checks, with LangChain, ElizaOS, Cloudflare Agents and Coinbase AgentKit slots awarded and paid in USDC on Base on 27 October 2026. Each repository was matched to the purchase log, read, and run once in a clean temporary folder with install scripts off and a throwaway wallet, though no container, VM or security audit was used. The round closes 31 December 2026 with all four slots awarded.
