A free wallet for your AI agent.
$0 per month. 0% on funding. 10% on outflows. Everything you need to test, demo, or run a small agent in production.
The Free plan is real, not a trial. Every Blockchain0x user starts here. Funding is fee-free; the 10% fee only applies when the agent autonomously spends or you withdraw. Your monthly subscription cost is zero. Many agents stay on Free permanently because their outflow volume does not justify the upgrade.

What "free" really means.

When Free is the right plan.
Four common patterns we see where Free wins and an upgrade would be wasted spend.
Pattern 1 - The demo agent you show on X
You built an agent for a launch demo or a side-project repository. It accepts tips on the public page; maybe ten people pay over a month for $50 total, none of which the agent ever spends back out. Inflow fee is $0 (funding is always free). The 10% outflow fee only kicks in if the agent actually spends or you withdraw - if you leave the $50 in the wallet, the platform fee is $0. Free is correct until traffic actually scales.
Pattern 2 - The portfolio of small agents in a workspace
You run 4-6 agents, each with low volume (a research agent, a code-review agent, a summarizer, a translator). Most stay on Free with light traffic; one or two might earn enough to justify Pro. The Free tier is what makes the portfolio model economical: you pay nothing for the ones that have not found product-market fit yet.
Pattern 3 - The "is this real" trust signal for a personal project
You are building an agent and want a credible public page to link from your GitHub README, blog, or X bio. The Free public page with the email-verified badge is enough to look legitimate. You may never enable payments at all; the page itself is the goal.
Pattern 4 - The pre-launch waitlist test
Before you write the agent's code, you publish the page describing what it will do, accept a $1 "early access" tip from early adopters, and measure interest. Free is exactly right for this: no commitment, the public page indexes immediately, and you can upgrade after the waitlist proves real.
The fee in concrete dollars, by outflow.
Funding is always 0% on every plan. The 10% outflow fee is debited in USDC from the agent's wallet at the moment each outflow (autonomous spend or withdrawal) confirms on Base. Use this table to project your cost before signing up.
| Monthly outflow | 10% fee | Recipient receives | vs Pro (would pay) |
|---|---|---|---|
| $10 | $1.00 | $9.00 | $29.40 ($29 sub + $0.40 fee) |
| $50 | $5.00 | $45.00 | $31.00 ($29 sub + $2.00 fee) |
| $100 | $10.00 | $90.00 | $33.00 ($29 sub + $4.00 fee) |
| $483 | $48.30 | $434.70 | $48.32 (break-even) |
| $750 | $75.00 | $675.00 | $59.00 ($29 + $30) |
| $1,000 | $100.00 | $900.00 | $69.00 ($29 + $40) |
The break-even point is about $483/month of outflow. Below that, Free is cheaper. Above it, Pro is cheaper and you also get the full API, webhooks, exports, and a higher Spend Permission cap - reasons to upgrade earlier than pure cost suggests.
Incoming payments are 100% fee-free on every plan. The agent receives the exact amount the customer sent; we never take a slice on funding or inflows.
What happens to a Free agent that goes inactive.
Free agents are not deleted, but unused ones are archived to keep the public-page directory clean and to avoid charging us for storage we are not earning revenue on. The policy is explicit, predictable, and reversible.
The 60-day inactivity timeline
Any activity (incoming payment, outgoing payment, API call, settings edit, dashboard visit by a workspace member) resets the clock to 0.
First reminder email: 'Your agent X has been inactive for 30 days. It will be archived in 30 days unless you act.'
Second reminder email with a one-click 'Keep active' button that does nothing but reset the timer.
Final reminder email, 24 hours before archive.
Archive: public page returns 410 Gone (not 404), removed from sitemap, API returns 'agent.archived' for the slug. Wallet address and transaction history are preserved in our DB.
Reactivation
Archived agents are listed in a separate section of your workspace dashboard. Click Reactivate on any of them and the agent comes back online immediately: public page returns 200, search engines re-index within 24-48 hours, the API stops returning archived for the slug. No data is lost.
Permanent deletion (optional)
If you want an agent permanently deleted (e.g. for GDPR right-to-erasure), the dashboard has a Delete option separate from archive. Permanent deletion removes the agent record, transaction history references from our DB, and frees the slug for someone else to claim. The onchain history at the wallet address is unaffected (that lives on Base, not on us).
Upgrade an agent the moment any of these is true.
The Free tier is intentionally limited so that paying customers stay paying customers and the economics work out. Below are the concrete signals that tell you Free is no longer the right fit for a specific agent. Note: you upgrade ONE agent, not your whole workspace. Other agents stay on Free.
- Your agent's monthly outflow crosses ~$483 (the Free -> Pro break-even)
- Your agent needs more than $50 in total spend authorization
- You want webhooks for real-time payment notifications
- You want to receive payments via the API, not just the public page
- You want exports or audit logs
- You want a Verified Agent badge for higher trust
The strictly cost-based break-even point is $300/month of incoming USDC. Most agents that cross that threshold also start hitting one of the other signals at the same time (a customer asks why there is no webhook, an integration partner wants exports, the $500/day cap blocks a real payment). Upgrade when any signal fires - do not wait for the pure-cost crossover.
