## Summary

SHARK introduces PayCall, a system that lets AI agents pay per API call over HTTP 402 instead of a credit card. The post says PayCall enforces a hard budget in code, issues signed receipts, and reaches the same accuracy at 54% of naive cost. It is built on Muse Spark and uses simulated money with a real payment mechanism.
