Arcus is now on @circle Agent Marketplace.

One listing brings 54 Arcus merchants and 119 paid APIs to every agent browsing the marketplace. Market data, image generation, weather, security intel and more, all in one place.

Agents find an API on Circle, sign the payment and Arcus settles it in USDC on @arc. Gas is abstracted away and calls start at a tenth of a cent.

No API keys. No accounts.
Just agents paying for what they use.

[Danny Organ @organ_danny]

Agents paying agents in USDC is the moment this all gets real.

2,000+ settlements through the Arcus facilitator.

1,000 on Saturday. 2,000 by Thursday. Four days to double.

Agents paying APIs in USDC on @arc, gasless, every one settled onchain. 36 unique payers across 58 merchants and 125 paid endpoints.

Next stop: 10,000.

[ARCUS @arcusdotnet]

Every Arcus merchant now speaks A2A.

All 58 merchants are live as A2A (@Google) agents, with 125 paid skills between them. Any agent that speaks A2A can read a merchant's agent card, call a skill and pay per call in USDC with x402.

The merchant quotes a price, your agent signs, and Arcus settles on Arc Mainnet. Gas is abstracted away and you are only charged when the work is delivered.

No API keys. No accounts.
Just agents paying agents on @arc.

[ARCUS @arcusdotnet]

Your agent can already call an API and pay for it on Arc.

Next, it hires other agents.

Something new is coming to every merchant on Arcus.

[ARCUS @arcusdotnet]

Every API on Arcus is now discoverable by any agent.

58 merchants and 125 paid endpoints, listed in the standard x402 discovery format. Agent wallets and indexers can find them, see the price, and pay in USDC on @arc without a custom integration.

No directory to scrape. No API keys. Just one URL.

AI is machine-native intelligence.
Crypto is machine-native money.

An important piece connecting both is machine-native payments.

That’s what Arcus is building on @arc: x402 infrastructure for agents to pay, settle, and coordinate onchain.

Machine-native intelligence needs machine-native rails.

[BlackRock @BlackRock]

AI is machine-native intelligence and crypto is machine-native money. Both AI and digital assets translate real-world inputs into formats machines can use. Our latest research looks at why that connection could become increasingly important as AI evolves. https://t.co/z5T88Orble

[Arc @arc]

The agentic economy needs trust and verifiability.

Arc gives AI agents trusted infrastructure to transact, coordinate, and prove what happened.

[ARCUS @arcusdotnet]

An AI-first economy needs payment infrastructure built for agents.

That's what we're building with Arcus on @arc.
From x402 payments to our new private transactions, enabling agents to transact autonomously with privacy built in.

The machine economy is taking shape.

[Arc @arc]

Arc is an AI-first economic operating system where agents can transact, contract, and coordinate.

On @tbpn, @jerallaire discusses Arc’s launch and why it’s such a huge milestone.

[ARCUS @arcusdotnet]

Private payments are live on Arcus.

Agents pay the Arcus pool with signed vouchers, and merchants get paid from the pool once a day. Onchain, nothing links your agent to the APIs it uses.

No public trail. No leaked strategy.
Just private agent payments on @arc.

[ARCUS @arcusdotnet]

Every x402 payment on @arc is public.

Which APIs your agent calls, how often, and what it pays. All onchain, readable by anyone.

Something new is coming to Arcus.

[ARCUS @arcusdotnet]

@organ_danny @USDC Bullish on USDC

[ARCUS @arcusdotnet]

Batch settlement is live on Arcus.

Until now, every x402 payment was its own onchain transaction. At $0.001 a call, the gas was worth as much as the payment.

Now an agent deposits USDC once, then pays every request with a signed voucher. Arcus collects the vouchers and settles them on @arc in bulk.

No per-call gas. No waiting on blocks.
Just a thousand payments in one transaction.

[ARCUS @arcusdotnet]

Every x402 payment today is its own onchain transaction.

That works at $0.10 a call. At $0.001, the gas is worth about as much as the payment itself.

Something new is coming to Arcus. Agents pay per request, merchants settle in bulk.

No per-call gas. No waiting on blocks.
Just payments that scale with usage.

[ARCUS @arcusdotnet]

1,000+ settlements through the Arcus facilitator.

100 on Thursday. 600 on Friday. 1,000 today.

Agents paying APIs in USDC on @arc, gasless, every one settled onchain. 26 unique payers across 56 merchants and 123 paid endpoints.

Next stop: 10,000.

[ARCUS @arcusdotnet]

Arcus now speaks Chinese.

The full site is live in Simplified Chinese: merchants, Studio, the live demo and $ARCUS. Same gasless USDC payments on @arc, now for builders who read Chinese first.

Arcus 现已支持中文。
智能体支付，在 Arc 上用 USDC 结算。

[ARCUS @arcusdotnet]

Every merchant on Arcus is now an onchain agent.

All 56 are registered on the ERC-8004 Identity Registry on Arc Mainnet. Each one has an agent id, a hosted agent card, and its paid endpoints listed as services other agents can discover and pay.

No directories to trust. No keys to hand out.
Just identities and payments, both onchain.

[ARCUS @arcusdotnet]

56 merchants. 123 endpoints. One way to pay.

Arcus now lists paid APIs for markets, weather, research, security, maps and media. Agents pay per call in USDC on @arc, gas abstracted away.

No keys. No signups. Just call and settle.
