CRA AGENT brings x402 to @arc: one tool call buys an API call for a fraction of a cent. Price read, policy checked, USDC settled gas-free through @circle Gateway, receipt written. Fully open source. MCP-native. CA: 0x70857041fef0ced97f9e01e7ccc21889afe3f6f4

Now building: CRA AGENT will take Circle Gateway payments from all 12 chains Circle settles, not only Arc. An agent with USDC in Gateway on Base, Arbitrum, Polygon or Ethereum will pay our routes from where its money already is. No bridging first, no gas per call.

You can now check a CRA AGENT receipt yourself: cra-agent.tech/verify#sample Your browser verifies both signatures, the wallet's and the post-quantum one, then asks Arc's precompile about the second. Nothing is sent to us. It covers the receipt, not the payment yet.

Started on post-quantum for CRA AGENT. An agent's receipt can now carry a second signature, SLH-DSA-SHA2-128s, the scheme Arc verifies on chain. We asked Arc's precompile on mainnet: valid. It covers the receipt, not the payment yet. github.com/giupy997/arcagent…

Every paid route on CRA AGENT takes payment three ways at the same URL: Circle Gateway on Arc, or plain x402 on Base or Solana. 22 routes, $0.0005 to $0.005 a call, charged only when the call succeeds. The OpenAPI lists each network with its price. api.cra-agent.tech/openapi.j…

2,421 x402 payments settled on CRA AGENT since Sept 20, 2,025 of them from wallets that aren't ours. About 105 a day over the last three days, up from about 60 the three before. only 6 failed in total (it was 150+ first week). Building CRA

gARC Applied to list CRA AGENT on Circle's Agent Marketplace. 22 endpoints: Arc onchain data, executed prices from real swaps, public sources as clean JSON. $0.0005 to $0.005 a call, through Circle Gateway on Arc or x402 on Base and Solana. Charged only when the call succeeds.

Any API can now bill agents by use on @arc. cra-agent-sell --price 0.10 --upto The agent signs once for up to $0.10. Your API answers with X-Charge-USD: 0.0123, and only that is taken. One header, no gas for the buyer, x402 upto underneath. Set it up: cra-agent.tech/factory#sell

Gm arc eco We're building the CRA app. Your agent in your pocket: it works 24/7 on @arc, pays for what it uses in USDC, and stays inside limits you set and it can't change. Every payment lands on chain, and you watch it happen. Set it and let it work.

Most agents keep USDC on Base. Paying on @arc needs it in Circle Gateway. Now it's one command: cra-agent fund 5 --from base Tested with our own $1: sent on Base, minted on Arc 24s later, in Gateway 5s after. Under a cent in fees. Solana works too. Via @eco and @circle's CCTP. Nothing is signed until Eco's quote is read from its own calldata: a CCTP burn of exactly that amount to Arc, minting to the agent, the fee under a cap, the refund to the same wallet. It's the owner's command. The model gets no tool to move money between chains. The test on chain: Base: basescan.org/tx/0xd4590848c4… Arc mint: explorer.arc.io/tx/0xcbee70e… Into Gateway: explorer.arc.io/tx/0x9753904…

We applied to @arc Microgrants with CRA AGENT. Agents pay per call in USDC over x402, under limits the model can't change, on Arc mainnet since day one. New: billing by use upto and funding from Base in one command. dorahacks.io/hackathon/arc-m…

Gm @arc builders. We now settle x402 "upto" on @arc: sign once for a ceiling, pay only for what you used. First payment, our own test wallet: a $0.10 cap to hire our think agent. It bought 3 LLM calls from @blockrunai and a web search from @ExaAILabs. $0.018265 spent + $0.005 fee = $0.023265. One signature, no approval tx, no gas for the buyer: USDC on Arc takes permits, so our facilitator submits the permit with the payment and pays the gas. Settled in one tx: explorer.arc.io/tx/0xb370750… How it bills: api.cra-agent.tech/v1/upto

CRA AGENT is now on @x402scan . All our paid routes are listed there, from live Arc data to web and package lookups. Any agent can try them from the page and pay per call in USDC on Arc, Base or Solana. x402scan.com/server/a2c650c5…

Gm @arc fam. we are builders and we keep and continue to build . So CRA AGENT is now available in Coinbase's x402 Bazaar and on their Agentic Market. All 22 of our paid routes are listed and paid in USDC on Arc, Base or Solana. Anything from live Arc data to web and package lookups. @CoinbaseDev settles Base and Solana, @circle settles Arc. agentic.market/services/api-…

Solana Lane is complete. Buyers pay our x402 sellers in USDC on Solana. Now it moves to Arc in one command. Tested with our own 1.5 USDC: sent on Solana, minted on Arc 34 s later, for $0.000037. Via @circle's CCTP. Nobody holds it in between. cra-agent.tech/lane

CRA Agent now has its logo and social media links updated across all Web3 wallets. The update for Arcscan has also been submitted and is currently under review. Later on, we will release more information on how x402 Lightning payments work, especially since CRA Agent now runs a Bitcoin node for this purpose. We also notice that users are utilizing CRA Agent for their own projects—that’s great to see.
