Agentic Index
Circuit & Chisel vs Rye (2026)
Both let agents buy things and they work at opposite ends of the transaction.
Rye is practical today: a Universal Checkout API turning a product URL and tokenized payment into a confirmed order on any merchant through browser automation, covering more than fifteen thousand stores with enforced spend controls plus returns and product data APIs, from 149 dollars a month for developers, documenting 6.5 of 14. Circuit and Chisel is building ATXP, an open protocol letting agents discover, negotiate and settle instant low cost micropayments with each other, at 4. Buy from existing merchants now, against a rail for agents paying agents later.
Choose Circuit & Chisel if
- Agent to agent micropayments are the future you are building for and a protocol is the right bet.
- Stablecoin settlement between agents is part of your architecture.
- You want to be early on an open rail rather than dependent on one vendor's coverage.
Choose Rye if
- Documented coverage is broader and you need agents buying real products today.
- Fifteen thousand plus stores through one checkout API is the coverage that makes this work.
- Enforced spend controls are what let you allow an agent near a payment method at all.
