You don't need to learn x402. You don't need a crypto library. You don't need to touch your server. Point MPP32 at your endpoint and set a price. Your API keeps receiving normal requests. Every one of them is already paid.

Fully involved🫡

Your agent finds a paid API that isn't in any catalog. Now what? pay_x402_url pays any x402 endpoint on the web, capped at $0.50 a call unless you raise it, and counted against your budget. Your agent key never goes to the other side. Any x402 URL returning 402 gets paid automatically, inside a $0.50 per-call cap and the session budget.

Your payment key stays on your machine. Full stop. The MPP32 MCP server runs locally and signs every payment on your device. We see a signed payment. We never see the key. mpp32.org/docs A laptop keeps a payment key inside a local boundary and sends only a signed payment to a server marked no key.

Understand what you hold

Mint your LFGEND and support the $M32 community! First communities to mint 44 LFGENDS as a whole wins a support package The @LFGOcommunity team will buy and lock up to 5k USD of $M32 tokens if we win! We can do this already minted one on my own, lets get some more to push us forward and make connections + partnerships.

Agents don't browse. They ask. "weather forecast, under a cent" goes in. A ranked shortlist comes out, sorted by health, verified ownership and budget fit. What would your agent ask for first? mpp32.org/catalog A plain query, weather under $0.01, passes through a filter into a ranked shortlist of three services with prices and health checks.

Your agent can't fill out a signup form. It doesn't need to. Add mpp32-mcp-server to any MCP client and it can search a catalog of 80,000+ services, see the price, and pay, all from inside the conversation. mpp32.org/docs A terminal running npx -y mpp32-mcp-server with 17 tools ready, connected to a grid of service icons labeled 80,000+

Networks drop. Agents retry. Paying twice isn't part of the deal. Paid calls through MPP32 are idempotent for 10 minutes. Send the same request again and you get the same answer, with no second charge.

What should an agent pay for a request that failed? Nothing. On x402 through MPP32, payment settles only after the API answers with real data. Errors and empty responses cost zero.

Big day coming for @LFGOcommunity

Happy to announce the @MPP32_dev community will be minting NFTs by @LFGO_LFGENDS from the @LFGOcommunity A great community that's been around for 2+ years and never stopped building, 1 token the whole time solana:2u98MM7DMtVmNG4iAKRNMtynjmkzgD6fXAzB3wVfhQvg now their first NFT mint ever. The benefits of our community minting gives us exposure on marketing and if we hit 44 NFTs minted the LFGO treasury buys solana:6hKtz8FV7cAQMrbjcBZeTQAcrYep3WCM83164JpJpump tokens and will lock or burn them! Keep your eye on solana:2u98MM7DMtVmNG4iAKRNMtynjmkzgD6fXAzB3wVfhQvg sitting at free prices right now for a community this large. solana:6hKtz8FV7cAQMrbjcBZeTQAcrYep3WCM83164JpJpump is going to get active with it.

Ready to mint!🔥

Your agent hires an agent. That one hires two more. Who's paying? Delegated Spend Keys give every sub-agent its own key: limited to the services you allow, capped, and counted against the parent's budget. Revoke one and its whole branch stops

Mix of all three. Primary session keys are 30 day and revocable. Delegated child keys are meant to be per-task, you mint one, use it, then revoke. x402 sessions sit around 30min TTL. Real limit is the budget plus velocity cap and the instant kill switch

Quantum risk is back in the timeline again, harvest now, decrypt later, tighter qubit estimates, and AI accelerating classical cryptanalysis. For agentic payments the real target isn’t “the chain dies.” It’s agent identity, spend mandates, and signing keys that authorize money movement. At MPP32 we’re treating this as a design constraint, not a distant headline: • Short-lived, scoped, revocable delegated keys + budgets and circuit breakers (blast radius stays small even if a key is compromised later) • Crypto agility in the authorization layer so we can swap in NIST PQC (ML-DSA signatures / hybrid schemes) for agent spend envelopes without forcing providers or agents onto one protocol • Local signing are keys never leave the agent machine; we verify, we don’t custody • Multi-rail so we can ride chains that are already moving toward quantum-safe options Preparation beats panic. The agent economy needs payments that stay unforgeable for years, not just the next model release. Building the universal proxy with that horizon in mind.
