I looked under the hood of both protocols (using the official docs).

Both leverage HTTP 402 for payment requests, but their architecture, positioning, and execution are totally different.

Here’s the technical breakdown"

x402 does one-off payments but MPP also does streaming

Yes… x402 is multi-chain while MPP runs only on Tempo"

But under the hood, it also includes features designed for enterprise-grade reliability and compliance.

Two examples: offer and receipt and idempotency extensions."

 Transactions are down, but volume is up hard

Agents holding $ZAUTH will be able to access RepoScan endpoints for free, while non-holders pay per request via x402.

This is a clean token-gated access model for the agentic internet.

The idea is simple. Agents need to find each other, talk, and pay each other.

Stack handles payments using x402 and ERC-8004, perkos-a2a handles communication, and Swarm coordinates the agent fleet.

One of the biggest, yet quietest launches lately.

The coolest thing I noticed is for sure MPP (Machine Payments Protocol).

It basically lets AI agents handle payments on their own without human input.

But what makes it different from x402 is how it"
