PRICING-MODEL RATIONALE

Why per agent, not per account.

Most SaaS pricing models meter on the customer: a flat monthly fee plus usage overages, where every project, workspace, and integration share the same plan. That model fits when one customer has one workload. It does not fit agent infrastructure. A single developer might run a low-volume demo agent, a high-volume MCP server, and a private internal bot - three workloads with three very different cost profiles. Charging the same plan tier to all three is either a bad deal for the cheap agents (forcing the customer into the highest tier any agent needs) or a bad deal for us (forcing us into a price low enough that the heavy agent loses money).

Per-agent pricing solves the mismatch directly. Each agent has its own plan, billed independently, sized to its own usage. A demo agent stays free. The MCP server moves to Pro the day it has paying customers. The internal bot moves to Business when audit logs become a compliance requirement. None of these decisions involve renegotiating a master plan or pretending the cheap workload is something it is not.

The model is Cloudflare-style: meter on the unit of work the customer cares about (Cloudflare on domains; us on agents), keep workspace-level features free or near-free (Cloudflare on accounts; us on workspaces), and let costs scale only with the workloads that actually generate revenue. This is the only pricing structure that survives a workspace with 5 free agents and 1 paying one without either side overpaying.

The short version

You pay for the agents that earn. Free agents stay free. There is no quota you can outgrow without warning, because every paid agent's pricing is independent of every other.

WORKED BREAK-EVEN MATH

Exactly when each tier becomes the right choice.

All numbers are monthly outflow per agent (autonomous spends + withdrawals). Funding the wallet is always free at 0%. Break-even points come from solving: subscription_fee + (outflow x new_outflow_rate) = outflow x old_outflow_rate.

Outflow / monthFree total (10%)Pro total ($29 + 4%)Business total ($49 + 2%)Best tier
$50$5.00$31.00$50.00Free
$100$10.00$33.00$51.00Free
$300$30.00$41.00$55.00Free
$500$50.00$49.00$59.00Pro
$750$75.00$59.00$64.00Pro
$1,000$100.00$69.00$69.00Pro or Business
$2,000$200.00$109.00$89.00Business
$5,000$500.00$229.00$149.00Business
$10,000$1,000.00$429.00$249.00Business

Free -> Pro break-even

$29 + 0.04V = 0.10V solves to V = $483/month outflow. Below ~$483, Free's 10% outflow fee is cheaper. Above, Pro is cheaper. Annual billing on Pro shifts break-even further down (Pro becomes $24/month equivalent on annual).

Other reasons to upgrade earlier: API write access, webhooks, the Verified Agent badge, exports. The math is just one input.

Pro -> Business break-even

$49 + 0.02V = $29 + 0.04V solves to V = $1,000/month outflow. Below $1k, Pro is cheaper. Above, Business is cheaper.

Other reasons to upgrade earlier: audit logs, the counterparty allowlist, higher API limits, priority support.

VS FLAT-RATE COMPETITORS

Why the per-agent line is steeper than a flat-rate line.

Per-agent looks more expensive at high volume on one workload. It is dramatically cheaper across the typical workspace shape (many small agents, a few earning ones).

ScenarioBlockchain0xHypothetical flat-rate ($99/mo)
Solo dev, 1 demo agent, $0 outflow$0$99
Solo dev, 5 demos + 1 earning agent ($500/mo outflow)$49$99
MCP operator, 1 agent at $1k/mo outflow$69$99
Agency, 12 agents (4 free, 6 Pro at $500/mo outflow, 2 Business at $4k/mo outflow)$552$99 (if it scaled)
Single-customer enterprise, 1 agent at $50k/mo outflow$1,049$99 + overage

The honest version: per-agent pricing is more expensive than a hypothetical $99/month flat rate when you have one massive workload. We are not the right pricing model for that case. The right pricing model for a single-customer enterprise with one $50k/month agent is a negotiated contract with quantity discounts, which is what proper enterprise infrastructure vendors offer once the volume justifies the conversation.

Per-agent dominates every other shape. The shape that matters most - "solo developer running a portfolio of small agents, one of which earns" - is the worst-case scenario for flat-rate pricing and the best-case scenario for ours.

HOW BILLING WORKS

Per-agent subscriptions, one consolidated workspace bill.

You can have unlimited agents on Free in one workspace, plus any combination of Pro and Business agents. We bill via Stripe under the hood: each paid agent is its own Stripe subscription (with its own subscription_id), all attached to the same Stripe customer (your workspace). You receive one invoice per agent per billing cycle, plus a separate invoice for transaction fees and any add-ons.

What happens on a new Pro upgrade

  1. You click Upgrade on an agent. We collect a payment method via Stripe Elements (card or ACH).
  2. Stripe creates a subscription with the Pro price and a prorated initial invoice covering the rest of the current calendar month.
  3. The agent's plan field flips to "pro" in our DB. API write access and webhooks unlock within seconds.
  4. Going forward, Stripe charges your default payment method on the first of each month. We do not store card details ourselves; Stripe handles PCI compliance.

What happens on a downgrade or cancellation

  1. You click Downgrade or Cancel on an agent. Stripe immediately cancels the subscription and credits the unused portion of the current period back to your workspace's invoice balance.
  2. The agent's plan field flips to "free" (downgrade) or remains "pro" until the period ends (cancellation, with grace period).
  3. API write access and webhooks remain available until the period ends, then revert to Free behavior. No data is lost; you simply lose the paid features.

Outflow fees

Outflow fees are debited in USDC at the moment each outflow confirms on Base. No monthly invoice for them, no fiat conversion - the agent's wallet balance reflects the fee instantly, and every outflow lands in the transaction log with its fee amount alongside. Per-agent subscriptions and add-ons remain on the standard Stripe monthly cycle billed in fiat.

ADD-ONS

Per agent, billed monthly. Optional.

Add-ons unlock specific extras without forcing a plan upgrade. Available on whichever plans we list per row.

Verified Agent badge ($9/agent/month)

The same Verified badge included on Pro and Business, available as an add-on for Free agents. Earned after GitHub or domain verification. Renders on the public page and in the agent's JSON-LD structured data. Useful when a Free agent has built reputation and you do not want to upgrade the full plan but do want the trust signal.

Premium profile ($5/agent/month)

Custom branding on the agent's public page: brand color, accent color, custom logo, custom hero image. Includes basic profile analytics (views, click-through-to-pay rate). Available on all paid plans.

Featured listing ($49/agent/month)

The agent gets pinned at the top of the relevant /integrations/{framework}/ pages and in the integrations index. High visibility for agents that are themselves built on a popular framework and want category discoverability. Pro and Business only.

API overage ($10 per 100k requests)

Pay-as-you-go beyond your plan's included API rate limit. Useful when traffic spikes; cheaper than upgrading to the next tier if the spike is short-lived. Billed monthly based on usage logs. Available on every plan including Free (above the read-only limit).

PLATFORM FEES EXPLAINED

Zero fees on funding. Platform fee only on outflows.

Inflows are 100% fee-free on every plan. Funding the wallet (USDC deposits from any source, customer payments, on-ramp purchases) credits the full amount to the agent. If a user funds $100, the agent has $100 to spend. Customer payments work the same way - the agent receives the exact amount sent, no platform deduction.

The platform fee (10% on Free, 4% on Pro, 2% on Business) applies only on outflows: autonomous spends to APIs, MCP servers, or other agents via the session key, and withdrawals back to the user's personal wallet. Same rate either way; we do not penalize withdrawal. The fee is debited in USDC from the agent's wallet at the moment the outflow confirms onchain.

On the recipient side, the counterparty receives the exact amount your agent intended to pay - the platform fee is debited separately from the agent's balance. This keeps the agent's outbound payment behavior predictable and the platform fee transparent in transaction logs. Per-agent subscriptions ($29 Pro, $49 Business; save 2 months on annual) and any add-ons are still billed in fiat via Stripe on the first of each month or annually if you choose annual billing.

FAQ

Frequently asked

Can I upgrade or downgrade an agent at any time?

Yes. Stripe prorates the change to the second. If you upgrade an agent from Free to Pro mid-cycle, you pay only the portion of $29 covering the remaining days that month. Downgrades work in reverse: the unused portion of the current period is credited toward the next invoice. The outflow fee rate changes are not prorated and apply only to outflows confirmed after the upgrade/downgrade takes effect. Annual subscribers can switch to monthly at the next renewal date.

Can I have a mix of free and paid agents?

Yes. That is the point. A typical Blockchain0x workspace has 5-10 free agents (used for experiments, demos, or low-volume operations) and 1-3 paid agents (the ones that actually earn money). Mixing is encouraged, not penalized. Your workspace gets one consolidated Stripe customer record; each paid agent is a separate subscription line item on the invoice.

What happens to a free agent that stops being used?

Free agents with no activity (no payments received, no API calls made) for 90 days are auto-archived. The public page is hidden from search engines, the API returns 404 for the agent's ID, but all transaction history and the wallet address are preserved. Re-activate from the dashboard at any time with one click; the public page comes back online and indexing resumes within 24 hours.

Do you offer enterprise plans?

Not at MVP. Heavy users land on Business and stack many agents within one workspace. If you genuinely need an enterprise contract (negotiated rates, MSA, dedicated support, SOC 2 attestation), talk to us in V1+. For most operators, Business + extra workspace seats covers everything an enterprise contract would have provided.

Why is the platform fee debited in USDC at outflow instead of billed in fiat?

Two reasons. First, autonomous outflows happen at agent speed, not Stripe-invoice cadence - debiting the fee at the moment the outflow confirms onchain keeps the platform fee in lockstep with the action it's pricing. Second, it makes the model honest about what we're charging for. We only touch money when it leaves the wallet on the user's instruction, never when it arrives. That keeps the regulatory story tight (we facilitate outflows, we do not process inflows) and the marketing story simple (funding is free; we earn only when value moves out). Per-agent subscriptions and add-ons are still billed in fiat via Stripe on the first of each month with proper invoices for VAT/GST.
