Para CEO Says AI Agent Payment Standards in Crypto Are Unlikely to Produce a Single Winner

Para CEO Nitya Subramanian says the race to define how AI agents make payments in crypto is not heading toward a winner-take-all outcome. Speaking on Unchained, she said Coinbase’s open payment standard x402 has gained an early edge with independent developers because it has been the easiest to implement, and that simplicity has driven much of the grassroots adoption seen so far. Subramanian’s view carries weight because Para provides wallet infrastructure for many of these systems and describes itself as relatively neutral across competing payment rails. She said x402 is well suited to high-frequency stablecoin micropayments, especially pay-per-API-call activity that dominates current agent-to-agent transactions, but argued that the model does not fit every form of agentic commerce. For larger purchases, she said, rival standards may be better positioned, particularly those that build in features such as recourse and dispute handling. Her takeaway is that adoption is likely to fragment by transaction type, much like traditional payment methods serve different use cases. She also pointed to ongoing governance changes around x402, whose foundation was formed by Coinbase, Cloudflare, and Stripe and is moving under the Linux Foundation, even as Stripe supports a competing protocol.

Para, a company that provisions wallets for AI agents, does not expect the fight over agent-payment standards in crypto to end with a single dominant winner.

Nitya Subramanian, chief executive of wallet infrastructure firm Para, said on Unchained that Coinbase’s open payment standard x402 has built an early lead among independent developers because it has been the easiest option to set up. That ease, she said, has driven most of the bottom-up adoption now visible in the market.

Her view matters because Para sits beneath many of these systems and, in her own description, takes a relatively neutral position across the competing rails.

Why x402 moved first

On the podcast, Subramanian said x402 is already well configured for microtransactions, especially the pay-per-API-call activity that now defines much of agent-to-agent payments. That makes it a strong fit for high-frequency stablecoin micropayments.

She also drew a boundary around that use case. Not all agentic commerce, she said, will take the form of pay-per-API-call transactions. For larger purchases, x402 is a weaker fit.

A market split by payment type

That is where she expects other standards to pick up share. According to Subramanian, some rival protocols build in more explicit views on recourse, disputes, and other features that become more important as transaction sizes increase.

Her conclusion was that adoption will fragment rather than consolidate. “It’s not gonna be one size fits all,” she said, comparing the outcome to conventional finance: “There’s a time and place for a credit card payment, and a time and place for an ACH.”

Competition is still taking shape

Agent payments have become a crowded field. x402 settles high-frequency stablecoin micropayments through a revived HTTP status code. Google’s Agent Payments Protocol and the Machine Payments Protocol backed by Stripe and Paradigm are pursuing different parts of the market.

The standards themselves are still sorting out governance. Coinbase, Cloudflare, and Stripe formed the x402 Foundation, which is now moving under the Linux Foundation, even as Stripe backs a competing protocol.

For builders choosing a rail, Subramanian’s framing was direct: the key question is not which standard wins, but which one fits the payment.
