So much alignment. Christian, I realized that verifiable is so important when execution is getting cheaper and cheaper. @BlockRunAI will spend more time to build eval and benchmarks for ai agents to help us to be more efficient, safe and predictable.

Top x402 Projects on @base x402 lets agents pay for digital services with USDC, turning APIs, data, inference, and tools into machine-purchasable products. 1. @BlockRunAI - x402 gateway for AI models, tools, data, media, RPCs, and compute. 2. @MeshGateway - 500+ machine-payable merchants connected to Google A2A and x402 endpoints. 3. @KorProtocol - KORUS lets agents discover licensed music stems, remix them, and settle royalties on Base. 4. @heurist_ai - AI research tools with Amazon Bedrock AgentCore Payments settling through x402 on Base. 5. @OpenGradient - private AI inference requests with encrypted prompts and x402 payments on Base. 6. @reppo - Eval API credits for agents and model evaluation through x402. 7. @xona_agent - agent wallets, spending limits, and x402 resources across Base and other networks. 8. @ClawBankHQ - Manfred searches and combines more than 1,000 x402 resources for agent workflows. 9. @useOttoAI - paid x402 endpoints for live yield data and tokenized-stock opportunities. 10. @miroshark_ - football simulations and detailed reports available through x402-paid endpoints. 11. @TavilyAI - live web-search access for agents through Coinbase’s x402 ecosystem. 12. @arkham - whale and smart-money data accessible through x402 payments. 13. @youdotcom - agents can pay for live web data on demand through x402.

BlockRun is building a useful link between AI work and payments. Its open-source ClawRouter chooses an AI model for each request, aiming to avoid paying for an expensive model when a cheaper one can do the job. The model choice happens on your machine. Requests then go through BlockRun, with an option to pay per request in dollar stablecoins on Base or Solana. There is attention beyond the team's own posts. ClawRouter has about 6.6K GitHub stars. Circle also described demos at a developer event with BlockRun, Dynamic and Fireblocks. That puts it on my technology watchlist. My next test is whether outside developers keep using it and get useful work done at a lower total cost. A cheaper answer that needs three retries may cost more. I care more about that than a huge payment count. If repeat use and reliable spending controls do not follow, the excitement can fade. I have not confirmed an official BlockRun token. Code:

@robbiepetersen_ Front on mine on the pure volume side is @BlockRunAI - buyers followed the service from @base to @solana - driving most of the vol on x402 at the moment. MPP still fairly quiet. Clearest vision on the space comes from @eastdakota

State of x402 on @base x402 on Base processed 29.9M transactions and $54.4M in payment volume over 30 days. The average payment was roughly $1.82, with 1.2 buyers for every seller. ■ @BlockRunAI gives agents pay-per-call access to AI models, search, market data, and onchain tools, with USDC settlement on Base. ■ @Arkham added x402 payments to its API, giving agents access to wallet flows and whale activity at request time. ■ @Apify opened 20k+ web automation tools to agents paying with USDC on Base. ■ @MonidHQ connects agents to 1,700+ tools and APIs through one discovery and payment interface. More than 12k unique sellers are offering paid services through x402. More services bring more agents, more agent payments bring more sellers, and the x402 economy keeps expanding on Base.

AI on Base 48H Recap what happened across AI, agents, x402, and robotics on @base: PRIVATE AI ■ @AskVenice completed its largest VVV burn at $391K and added GPT Image 2.5 Flare and Sunburst. ■ @OpenGradient processed 3.7B+ tokens through 588K+ private inferences, with prompts encrypted before inference. ■ @usedotai processed 1B tokens in a single day and is preparing autonomous private agents that run directly on users’ computers. AGENTS ■ @aeonframework’s x402aff standard became an official x402 Foundation extension. ■ @openservai is opening its public API through hackathons and builder events. ■ @Agent0ai is moving agent-run code into disposable gVisor sandboxes. ■ @officialbunnyos allocated 500 NFT whitelist spots across agent players, token holders, and the public. ■ @wardenprotocol added one Halo account for agent identity, balances, and delegated spending. X402 ■ @KorProtocol enabled agents to read music licenses and complete purchases through Base MCP and x402. ■ @BlockRunAI joined Circle and Fireblocks to demonstrate agent wallets, service discovery, and USDC payments. DATA AND COMPUTE ■ @b3labs is financing and hosting NVIDIA hardware for inference workloads. ■ @sibylcap shipped Memory 0.8.1 while 365 teams continued building for its agent-memory hackathon. ■ @peerxyz added direct ZEC purchases through familiar payment apps without routing users through a centralized exchange.

➟ @solana is becoming x402’s machine-payment home. > 37M+ x402 transactions. > 20K+ buyers & sellers. > ~70% of monthly x402 volume. In one 7-day stretch, @BlockRunAI settled 5.4M agentic payments through @PayAINetwork, including 3.3M USDC transfers. That scale matters because most x402 payments are tiny. Agents are paying per request for inference, APIs, search and data thousands of times a day. The stack around that flow is also filling out: ❱ Settlement @PayAINetwork / @corbits_dev / @Figment_io ❱ Paid data & services @BlockRunAI / @syra_agent / @coing ecko ❱ Discovery @xona_agent / @x402scan ❱ Identity & credit @saidinf ra / @t54ai ❱ Agent execution @OOBEonSol / @elisymlabs / @WURKDOTFUN x402 on Solana is moving from a payment standard into machine commerce infrastructure. Transaction count is already scaling. Next, watch revenue per agent, repeat spend, and how much of this activity turns into real economic demand.

most agent requests don't need a frontier model. we measured it. ClawRouter reads each request and routes it to the cheapest model that can actually do it. same Hermes, Codex, and OpenClaw workloads, 84% under an all-Opus bill. @ClawRouter_ . Open source, runs locally, pays for itself in USDC.

Everytime I talked to Jeff, I feel I learn a lot. @BlockRunAI has been the largest x402 merchant in the world, and delivers 40m transactions on @solana and @base We start to see responsibility to do benchmarks and evaluation for helping agent get efficiency. Pay for the outcome with eval support.

Everyone will experience the agentic world. We truly appreciate the leadership from @circle and @FireblocksHQ, and a big thank you to @dynamic_xyz for demoing with us and showing what’s possible when agentic payments become real.

We spent an evening in NYC with @BlockRunAI @dynamic_xyz, and @FireblocksHQ exploring what agents need to transact. Circle Agent Stack gives builders the infrastructure to create agent wallets, set policies, discover services, call APIs, and pay in USDC. Strong demos, sharp questions, and a room full of developers building toward the agentic economy. Give your agent the tools to transact:

The agentic activities launchpad on @base Now officially live, with a weekly USDC reward pool for the 300 most active agents. One click spins up your agent. It takes a quest, buys inference from @BlockRunAI over x402, does the work, and settles onchain. A paying customer of the machine economy from task one. First quest up: Verdict.
