Use mpp dot dev guides upgrade-x402.md as reference. Add mppx to my existing x402 server. Use the Tempo payment method with USDC. Keep the same pricing and route structure. Add mppx.charge to each paid endpoint. Point out areas where I could benefit from adding sessions.

Been testing x402 with Veil.Cash x402 endpoint, signing via EIP-3009, send USDC with no onchain link across Base - fluidkey.eth to get a fresh PayTo address each time - x402 filled via Coinbase 🛡️ facilitator - USDC sent out from Veil relayer Result: no link between in/out txs. Agents just hit one endpoint + sign. Still early, but promising.

everyone’s yapping about x402 but i have a fun task for u to try - go to the link (in next tweet) - post a tweet and watch the twitter agent get paid in real time with x402 - learn how x402 works with the dev logs in the sidebar 🫡 report back with what you’ve learnt about x402

I’ve been watching x402 since Coinbase 🛡️ launched it in May 2025. I did a quick research pass. Here’s the snapshot ↓ Early integrations: • CoinGecko: x402 pay-per-use access for agents (shared by Coinbase Developer Platform🛡️). • Vercel: x402 AI starter template (x402 + modern AI stack demo). • Firecrawl: x402-powered search endpoint (pay per request). • Concordium: x402 + native age verification for agent payments. • Multiversᕽ: “agentic payments” built around x402 support. • AltLayer: building an “x402 Suite” for value exchange between agents. • Solana claims x402 has processed 35M+ transactions and $10M+ volume since launch. TL;DR x402 turns HTTP 402 “Payment Required” into a payment flow. A server returns a price for a request. The client pays in stables like USDC. Then the server returns the result. → Coinbase launched x402 via Coinbase Developer Platform (May 6, 2025). → Coinbase + Cloudflare announced the x402 Foundation (Sep 23, 2025). → Cloudflare added x402 support into its Agents SDK + MCP servers. Why? - AI agents need a clean way to pay for tools. - Data, compute, APIs, services. - No accounts, cards, or subscription screens. x402 is trying to make pay-per-request feel normal. Use cases that already make sense → Paid APIs Pay per call instead of subscriptions. → AI tool calls Pay per query, per inference, per task. → Agent-to-agent payments Software paying software automatically. → Micropaywalls Pay for one endpoint, one action, one piece of content. If this takes off, stablecoins stop being a story. They become how apps and AI agents pay for things online.

I built a miniapp that lets you post to the Base app & Twitter at the same time. Each user gets 1 free Twitter post per day to prevent hogging the X API quota. After that, posts cost 2 USDC, powered by x402 from Coinbase Developer Platform🛡️. 10 mins of integration effort lets me charge per usage on my API endpoint. Highly recommend if you’ve got a similar use case.

Apify has partnered with Coinbase to add more than 20,000 of its web automation Actors to the x402 ecosystem, giving AI agents thousands of tools they can discover, pay for, and run on their own. When an agent calls an Actor, it gets back an HTTP 402, settles the payment in USDC on Base, and the Actor runs. Built on x402 by Coinbase.

Calling x402 endpoints isn't cool. You know what's cool? Letting AI agent's call x402 endpoints. I made a quick demo showing how to make an agent in AgentBlocks that can choose which x402 services to use, call & pay them, and combine the results. Check it out:
