FREE PLAN

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.

$0per agent / month
0% inflow fee, 10% outflow fee

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 YOU GET ON FREE
  • A public profile page at wallet.blockchain0x.com/a/{your-agent-slug}
  • A non-custodial USDC wallet on Base
  • Basic transaction log (last 100 transactions visible)
  • Spend Permission cap up to $50 total per agent
  • Daily outflow cap of $100 per agent
  • Email verification badge (automatic)
  • Read-only API access (list agents, list transactions)
  • Community support via Discord
WHAT YOU DO NOT GET ON FREE
  • Webhooks (no programmatic payment notifications - polling only)
  • Full API write access (cannot create payment requests via API)
  • Custom branding (Blockchain0x branding shows on the public page)
  • Exports (no CSV/JSON download)
  • GitHub or domain verification (can be added as a $9/month badge add-on)
FREE TIER LIMITS

What "free" really means.

  • Max 5 active free agents per workspace
  • $100 per agent per day in outflow volume (autonomous spends + withdrawals)
  • Spend Permission max cap of $50 total per agent
  • Free agents with zero activity for 60 days are auto-archived
REAL-WORLD SCENARIOS

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.

WHAT 10% MEANS

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 outflow10% feeRecipient receivesvs Pro (would pay)
$10$1.00$9.00$9.40 ($9 sub + $0.40 fee)
$50$5.00$45.00$11.00 ($9 sub + $2.00 fee)
$100$10.00$90.00$13.00 ($9 sub + $4.00 fee)
$150$15.00$135.00$15.00 (break-even)
$200$20.00$180.00$17.00 ($9 + $8)
$500$50.00$450.00$29.00 ($9 + $20)
$1,000$100.00$900.00$49.00 ($9 + $40)

The break-even point is $150/month of outflow. Below that, Free is cheaper. Above it, Pro is cheaper and you also unlock 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.

ARCHIVE POLICY

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

Day 0

Any activity (incoming payment, outgoing payment, API call, settings edit, dashboard visit by a workspace member) resets the clock to 0.

Day 30

First reminder email: 'Your agent X has been inactive for 30 days. It will be archived in 30 days unless you act.'

Day 45

Second reminder email with a one-click 'Keep active' button that does nothing but reset the timer.

Day 59

Final reminder email, 24 hours before archive.

Day 60

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).

WHEN FREE BECOMES THE WRONG CHOICE

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 $150 (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.

FREQUENTLY ASKED

Four Free-plan questions worth answering.

Is Free really free, or will I get billed eventually?

Free is really free. No monthly subscription, no card on file required at signup, no surprise charges, and zero fees on funding (the agent receives 100% of every incoming payment). The only money that ever flows to us on Free is the 10% outflow fee, debited in USDC from the agent's wallet when the agent autonomously spends or you withdraw. If the agent never spends and you never withdraw, your lifetime cost to us is $0.00. We do not charge for signup, for the public page, for the wallet itself, for receiving payments, or for read-only API access.

Can I upgrade a single agent to Pro without losing any data?

Yes. Upgrading flips one agent's plan from free to pro in our DB; the wallet address, transaction history, public page URL, verification badges, and accumulated reputation all carry over instantly. The only changes are: API write access unlocks, webhook deliveries start, exports become available, the outflow fee drops from 10% to 4%, the Spend Permission cap raises from $50 to $10,000, and Stripe starts billing $9 per month prorated. Downgrades back to Free work the same way in reverse.

What counts as 'activity' for the 60-day archive timer?

Any of these resets the 60-day timer to 0: receiving a USDC payment (success or failed), making an outgoing payment, an API call that touches the agent (even read-only), an edit to the agent's settings, or a visit to the agent's public page from an authenticated workspace member. Anonymous public page visits do NOT count - that would let a competitor keep your agent alive by visiting it. We email you at days 30, 45, and 59 of inactivity so the archive never happens by surprise.

Can I have multiple Free agents and one Pro agent in the same workspace?

Yes. A single workspace can hold up to 5 active Free agents plus an unlimited number of Pro and Business agents simultaneously. Each agent is billed independently. The typical pattern we see: 3-5 free agents (demos, experiments, low-volume side projects) plus 1-2 paid agents (the ones that actually earn). Mix and match freely; the workspace itself is free.

Start free. No card required.
