Build a startup GTM agent with Circle Agent Stack. This tutorial walks through how an agent can: → Research a lead → Pay for enrichment with USDC → Write an outreach brief → Send the final output → Return a receipt log

Circle builders shipping great tools for builders 🔨

x402 and USDC are the perfect match

excellent write up. This is EXACTLY the steps i took to create @watch_eve . Worked like a charm.

x402 ❤️

💎💯

thank you, @bleso_a! i will test it and also try to create a tutorial video for the @arc community

seeing solid dev tools built out makes this whole space more legit this is what’s needed for real adoption

can we bring this to puffo?

This is where AI agents start looking like real businesses not chatbot.

The receipt log is the part we would keep. AgentFi needs the spend and the output on the same ticket.

AI agents that can research, pay, execute and return receipts are starting to look less like assistants and more like autonomous operators.

This is huge for automating GTM! Love the USDC payment integration. Definitely checking this out.

I’m on it

I Build In circle

Agentic payments make USDC useful as machine-to-machine money, but the hard problem is policy: spending limits, approved counterparties and recovery matter as much as signing. Autonomous wallets need controls comparable to corporate cards.

this makes agent payments easy to understand

usdc-powered agents doing actual work is getting interesting fast

The receipts + budget controls are the important part: agents need verifiable settlement, not just a generated answer. USDC makes the spend legible; Arc’s low-friction transactions could make this pattern useful well beyond demos.

the receipt log is the part that makes an agent workflow usable in production. if it records what was researched, what was paid, what was sent, and why, the human can audit the outcome instead of trusting a black box. that same trail matters even more when the workflow touches financial data.

I can't wait to see what developers are capable of building with this stack. AI + USDC is the future

the receipt log is the part i'd build first. on devnet the enrichment step is where cost runs away quietly, one lead turns into forty api calls. a running total the agent can read back is worth more than a per-call price.

circle turning usdc into the payment rail for autonomous work is a pretty compelling use case

If circle builds everything as part of developer advocacy, what’s left to build with the stack 🤦🏽

Arc

paying for lead enrichment with usdc is exactly the kind of agent workflow that actually makes sense

Pay-for-enrichment is the use case. If the lead-gen endpoint swaps its payout address overnight, budget + receipt is not enough. Allowlist the vendor. Hold until delivery

"Return a receipt log" — that's the line that matters. Next step for this stack: receipts that prove the work was done, not just that USDC moved. That's the rail we're building on @solana. 🏗️

20 tools in one? i’m skeptical. how does it actually handle data sync without breaking everything?
