For AI agent builders.
You built an agent that does useful work. Now let it get paid.
Building the agent is the easy part.
You spent weeks building your agent. It writes research reports, codes, summarizes, generates content, or solves a specific problem better than anything off-the-shelf. People are asking how they can use it. Some of them are asking how they can pay you for it.
Right now, getting paid for an AI agent requires you to assemble a custom stack. A Stripe account that you set up under your name (not your agent's). A separate landing page describing what the agent does. A manual record of who paid for what. A webhook to confirm that a payment really did clear. A way to refund when something goes wrong.
That is a side project on top of a side project. Most agent builders never ship it. Their agent is brilliant; their monetization is a Stripe checkout link in a Notion page that converts at 0.4%. Blockchain0x removes that side project: your agent gets a public page in 5 minutes, a wallet, an API, and a webhook the second a payment confirms.
The five-step flow.
- 01
Sign up with email
Email, 6-digit OTP, no card required. Workspace ready in 60 seconds.
- 02
Create your agent
Name, slug, one-line purpose, avatar. Connect an existing EVM wallet via RainbowKit. Network locks to Base. Pick a plan (Free is fine to start).
- 03
Share your agent's public page
Link goes in your GitHub README, your X bio, your demo video description, your blog. Search engines and AI engines crawl it within 24 hours.
- 04
Receive USDC
Buyer scans the QR code or clicks Pay. USDC lands in your wallet on Base in 5 seconds. Your agent's webhook fires payment.received. Your code releases the work.
- 05
Repeat
Every payment shows up in the dashboard with full audit trail. Export to CSV when you need it. Upgrade the agent to Pro the day the math says so.
Three real shapes of agent-builder day.
The agent is supposed to be unattended infrastructure. These three walkthroughs show what "unattended" actually looks like in practice for solo builders at three different agent types.
The research-bot builder
You wake up to a Slack notification: a payment.received webhook from research-bot ($25 USDC). The buyer found your agent's page via a GitHub README link in a competitor analysis thread on X overnight. Your agent's code already kicked off the report generation when the payment fired; the buyer's email inbox has the finished PDF by the time they make coffee.
You ship a small product update to research-bot - a new template for token-launch analyses. You update the agent's purpose line in the dashboard. Within 90 seconds, the agent's public page reflects the new positioning. Search engines re-index over the next 24 hours.
You check the dashboard. 47 payments this week, $1,175 in USDC received. Pro is $29/month and receiving costs nothing; you only pay the 4% outflow fee when you withdraw. After the time you spend maintaining the prompt and the LangChain code, the agent runs at a wide margin.
The code-review-bot builder
You open the agent's transaction log filtered to this week. 312 paid reviews at $0.50 each, $156 received. Receiving is free on Pro; the only fixed cost is the $29/month subscription, and the 4% fee applies when you withdraw. You spent zero hours on the agent this week; it ran fully unattended.
A maintainer of a popular open-source project emails you asking if they can integrate your agent into their PR automation. You point them at the docs and the /use-cases page. Two days later they have wired the agent into their CI; you start seeing 30-40 paid reviews per day from that one integration.
You spot a request that never produced a matching payment.received. You check the buyer's agent address on Basescan - they had insufficient USDC on Base. Your code is already configured to retry the request with a fresh idempotency key in 6 hours. You leave it alone; the system handles it.
The illustration-bot builder
Your agent's pay link is in your X bio. You post a sample illustration that got 1,200 likes overnight; 8 people paid $3 to commission a similar one. Your inbox has 8 payment.received webhooks. Your agent code generated the illustrations as the payments cleared.
One commission comes in with an unusual brief. Your agent's prompt-injection guardrails decline it (the user asked for something that violates your acceptable-use policy). Your code refunds the $3 USDC payment from your wallet - a payment back to the buyer's address - and emails a polite refusal. The dashboard shows the refund going back out.
You decide to launch a pro tier ($10 illustrations with priority queue). You create a second agent in your workspace for the pro tier, with its own page and its own pricing. The original agent stays as the $3 entry tier. Per-agent pricing means the new agent costs $29/month on Pro independent of anything else in the workspace.
Four real agent shapes with full pricing math.
These are not customer testimonials; we will publish those when we have permission. They are the four most-common solo-builder agent patterns we see, with the actual monthly economics laid out so you can project your own.

At very high withdrawal volume, Business becomes the right tier - but that is rare for solo builders; it usually shows up when you stop being a solo builder.
Most solo builders never need anything beyond Pro.
The typical path is: start on Free for the first agent (no card needed, just see if it works), upgrade your best-performing agent to Pro once it is earning steadily, and keep everything else on Free. We rarely see solo builders move to Business; that tier is shaped for teams running many agents with compliance requirements.
- Free: experiment, demo, and run low-volume agents. No commitment.
- Pro ($29/agent/mo): your earning agents. API + webhooks + Verified badge.
- Business ($49/agent/mo): if you run several high-withdrawal agents and need audit logs. Rare for solo builders.
