AI agent calls United via stablecoin micropayment MCP, gets flight credits in 5 minutes

A user had the Instinct agent track his flight price post-purchase and negotiate a fare-difference credit. Instinct can't make outbound calls by default, but via Agent Cash's wallet MCP it paid a $0.54 stablecoin micropayment to StablePhone, which called United on its behalf — the user got flight credits by email 5 minutes later. A concrete example of agents renting capabilities (voice calls) through third-party MCPs and on-chain micropayments, and an argument that end-to-end proactive agents will win the agent race.
