USYC is live on Arc, and it's already in CRA AGENT.
Our agent reads it from its contracts on Arc: the price its Teller mints and redeems at, the yield that price shows, and the supply on Arc.
Any agent can buy that data per call with an x402 payment.

CRA is now autonomous.
CRA integrated @blockrunai's LLM through x402: every thought is a paid call, every fact a tool bought from the bazaar. No API keys, just a wallet and a budget in USDC on @arc.
First agent on Arc that pays for its own thinking.

The CRA Bazaar is live.
Everything an agent can buy on Arc, in one place: 486 paid APIs from 6 sellers, from web search and blockchain RPC to AI models, email and company data. 446 of them can be paid from Base too.
Search it, browse by seller, filter by the network your agent pays on.

GoPlus is showing a honeypot warning on CRA and some other project on arc. It's a false positive, and we've reported it.
GoPlus's own report shows 0% buy and sell tax, no blacklist, no pause, no mint. On-chain, CRA had 288 sells in the last 24 hours on the main Uniswap pool.
The flag most likely comes from tiny pools other people created for CRA with 30–93% fees. Trade on the main pool linked from our site.

21.6M CRA bought back and burned so far, 2.16% of supply. 1M of that in the last 24 hours.
$13.5k in USDC paid out by the fee distributor.
All of it read from Arc, each burn and payout with its transaction: cra-agent.tech/token

CRA AGENT is now agent #186 in the ERC-8004 registry on Arc mainnet.
We registered it from the same address buyers pay, so you can check on-chain that the payee and the identity are one: ownerOf(186) and getAgentWallet(186) both return 0x33b3…Ea74.
The CRA agent checks this too now. Put identity=required in its spending policy and it only pays sellers that have an ERC-8004 identity on Arc.
For Arc builders: the registry is live on mainnet at 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432
The Arc docs still only list the testnet one.

Shipped arc_search for the CRA agent today.
You tell your agent what you need, like "btc price", and it searches what's for sale on Arc, checks each price against its own spending limits, and pays one it's allowed to. You don't have to give it the URL anymore.
For now it only finds our 21 endpoints plus whatever is listed on cra-agent.tech/market. If you sell an x402 API on Arc, list it and agents will find it.
The search is free to call too: api.cra-agent.tech/v1/market…

Two days ago we said our facilitator only settled for us, and that we'd open it if someone asked. Someone asked.
If you sell an API on Arc, our facilitator now settles for you too. It's what lets a person with a browser wallet buy from you, not just an agent: they sign an authorization, we submit it and pay the gas.
Register once by signing a message with the wallet that gets paid. No transaction, nothing moves, nobody can register an address they don't hold. Then one flag: --facilitator cra
gas is ours, so each wallet gets 200 settlements a day.
More big updates are in the pot for today.

This is the shape of it: an agent that pays for data mid-task instead of holding a subscription.
Same protocol on our side, different wallet model. The agent pays from its own wallet, under a budget it can't raise, and signs a receipt for every call. Seller side, one command puts an x402 price on any API.
If your Coinbase agent trades crypto, here's live data it can pay for today, on Base or Arc: Bitcoin, Ether, euro and CRA priced from real swaps on Arc, all pairs in one call with a freshness figure on each.
api.cra-agent.tech/v1/paid/m…
You can now trade stocks through Coinbase for Agents.
Crypto. Derivatives. And now 6,000+ stocks.
Need analytics or data on those stocks? x402 payments let your agents pay for live market data mid-task, from your USDC balance on Coinbase. No subscriptions needed.
The most comprehensive agentic trading tool available today.
Build responsibly.

76% of x402 runs on Solana.
CRA just connected it with @arc.
First x402 rail on Arc that takes payments from Solana. An agent on Solana pays in USDC on its own chain, no bridge, no SOL, and buys Arc-native services. Live today, first payment already on-chain.
Solana first. Base next. Then every chain x402 runs on.

Until now, "paid APIs on Arc" meant ours and one other shop. That changes today.
If you run an API, this puts a price on it. No code changes, no account, no key held anywhere:
npx -y @cra-agent/seller --target your-api.com --pay-to 0xYourWallet --price 0.002
A caller who hasn't paid gets a 402 with the price. A caller who has gets your API's answer, untouched. If your API fails the call, nobody is charged. USDC lands in your wallet's Gateway balance; one command withdraws it.
Then list it: cra-agent.tech/market
The market takes nothing on your word. We call your endpoint once without paying and show only what it says: the price, who gets paid, whether it still answers.
Four questions write the command for you: cra-agent.tech/factory#sell
Buyers: any x402 agent. Ours pays within limits it can't change.
Next step open the facilitator for registered users.

cirBTC is trading on Arc, so our price oracle now reads it.
Not a quote from an exchange somewhere else. The price people actually paid on Arc, swap by swap, with the routed hops and the mispriced legs thrown out. Same method we use for EURC and CRA. Eth too.
Free: api.cra-agent.tech/v1/fx?sym…
For a third of a cent you also get the price by trade size and where the volume went: cra-agent.tech/try
Bitcoin liquidity is now live on Arc.
cirBTC brings 1:1 BTC-backed collateral into Arc’s stablecoin-native ecosystem, helping BTC become productive across lending, trading, collateral, settlement, and treasury workflows.
BTC as collateral. USDC as borrow and settlement asset.
A stronger foundation for onchain credit markets.

The CRA Factory is live.
cra-agent.tech/factory
Four questions: where your AI lives, how much it may spend a day, which sites it may pay, which network. You get one line to paste in a terminal.
That line installs the agent, creates its wallet on your machine, writes the config into Claude or Cursor for you (and keeps a copy of the old one), and prints the address to fund. Send it a dollar, restart your AI, and it can pay for an API call on Arc by itself, in USDC.
The page never sees a key. It's made on your computer, by open source code you can read first. There's a "by hand" section that shows every step the command takes.

Gm @arc builders.
Quick follow-up on fees, since people asked.
The 1% tax runs by contract: liquidity, buyback and burn, USDC to holders, marketing. Nobody decides that, it just executes. So far: 1.82% of the supply burned and $3.2k in USDC distributed, every transaction listed at cra-agent.tech/token
building also a tracker for check how much is/was injected to the LP.
The creator fees are separate, and they land in my wallet. I've been putting them into marketing and extra buyback and burn since day one. Making it official: that's where they'll keep going. Not into my pocket.
Burns are on-chain, so you don't have to take my word for it.
102 wallets paid for an API call on Arc through us in the first day. None of them are ours, and you can count them yourself: cra-agent.tech/status
Almost all of them had to be on a computer. Most of you are reading this on a phone, where the page can't find your wallet.
That's the next update: pay from your phone. Open the page, pick what you want, sign in your wallet app, get the data. Same one signature, same third of a cent.
Shipping this today. more big updates at the right time.
$CRA
Almost 3k$ already sent to our holders , 1.75% supply bought back and burnt and also over 4k usdc injected to the LP .
A Big update incoming in a few hours .
