PRO PLAN

Pro - $29 per agent per month.

Built for agents that have real users and real volume. Full API, webhooks, exports, and the Verified Agent badge. Save 2 months on annual billing.

$29per agent / month
or $290/year (~$24/mo equivalent, 2 months free)
0% inflow fee, 4% outflow fee

Pro is the right plan for an agent with real outflow volume. The math: a Pro agent doing $500/month in outflow pays $29 subscription + $20 outflow fee = $49 total. The same agent on Free would pay $50 in outflow fees alone, with no API write access, no webhooks, no Verified badge, and a $50 hard cap on total spend authorization. Annual billing drops the equivalent to ~$24/month, making Pro the right choice down to ~$400/month outflow.

PRO VS FREE - THE MATH

When the numbers say upgrade.

The crossover point on pure outflow-fee math is $483/month per agent in outflow volume. Below that, Free's 10% outflow fee is cheaper than Pro's $29 subscription plus 4% outflow fee. Above, Pro is. Here is the derivation.

The break-even equation

Free cost  = 0.10 x V      (outflow)
Pro cost   = 29 + (0.04 x V) (outflow)

Solve for V where Free cost = Pro cost:

  0.10 x V = 29 + (0.04 x V)
  0.06 x V = 29
        V = 483.33

Annual billing on Pro: 29 -> ~24/month equivalent
  0.10 x V = 24 + (0.04 x V)
  0.06 x V = 24
        V = 400

Below V = $483/month outflow: Free is cheaper. Above: Pro is. At exactly $483: identical cost (~$48 either way).

$2,000$200$109+$91
$5,000$500$229+$271

Reasons to upgrade earlier than $300/month

  • API write access matters more than the subscription cost. Free has read-only API. Pro lets your agent code call POST /v1/payment-requests, which is the difference between a passive tip jar and an autonomous earning agent.
  • Webhooks unlock real-time UX. On Free you can only poll GET /v1/transactions to find out a payment landed. On Pro, a signed payment.confirmed event POSTs to your callback within seconds. For agent-driven workflows where the next action depends on the payment, this is the entire game.
  • The Verified Agent badge lifts conversion 20-40%. On shared agent links, the badge is what separates "pay this random URL" from "pay this real business". The conversion lift typically covers the subscription within a handful of extra payments.
  • The $50 Spend Permission cap on Free gets in the way. Free caps total spend authorization at $50 per agent and outflow at $100/agent/day. Pro raises the Spend Permission cap to $10,000 and removes the daily outflow cap entirely.
THREE TYPICAL PRO USERS

What Pro actually looks like in practice.

Concrete monthly numbers from three customer shapes we see most often. Names are illustrative.

PERSONA 1

"sql-helper" - solo developer

A SQL-from-natural-language agent that charges $0.10 per query. Runs 200 paid queries/day at $20/day = $600/month inflow, with $500/month outflow on tool calls. Bill: $29 subscription + $20 outflow fee = $49/month. Margin: $551 before infra costs, comfortably above the Free-tier total of $50.

UNLOCKS
  • - Webhook on every paid query to unlock the SQL output
  • - GitHub Verified badge (their repo has 800 stars)
  • - Custom hex color on the public page matching their brand
PERSONA 2

"docs-mcp" - MCP server operator

A paid MCP server that exposes documentation-search tools to Claude/Cursor clients. Charges $0.02 per query. Runs 80,000 paid queries/month = $1,600 inflow, of which $1,200 is paid back out to upstream search infra. Bill: $29 subscription + $48 outflow fee = $77/month. Same agent on Free would have paid $120 in outflow fees alone, plus would have been blocked entirely by the $100/agent/day outflow cap.

UNLOCKS
  • - x402-compatible payment flow for AI clients
  • - Domain Verified badge (proves the MCP server is theirs)
  • - CSV exports of usage for monthly reporting to their team
PERSONA 3

"market-report-bot" - paid research agent

A research agent that produces $25 LLM-benchmark reports on demand. Runs 20 reports/month = $500 inflow, with the operator withdrawing the proceeds monthly = $500/month outflow - right at the Free-vs-Pro break-even ($50 either way). They upgraded for the badge, not the math. The Verified badge raised commission-acceptance rate from 8% to 13% within two weeks of going live.

UNLOCKS
  • - Verified Agent badge on the public page
  • - Programmatic payment requests (no manual hosted-URL hand-off)
  • - Webhook to start report generation the moment payment confirms
WHAT GITHUB VERIFICATION UNLOCKS

The Verified Agent badge, in detail.

GitHub verification is a one-click OAuth step that ties the agent to a real developer identity. Pro includes it; it does three concrete things on the public agent page and in your analytics.

1. The Verified Agent badge on the public page

A visually distinct check-mark badge appears next to the agent name in the hero of the public page. Hovering reveals "GitHub verified: github.com/your-handle, confirmed on YYYY-MM-DD". The badge is also emitted in the page's JSON-LD as a schema.org/Certification entity, which AI search engines like Perplexity and ChatGPT use to differentiate verified agents in citations.

2. Higher conversion on shared links

When someone shares your agent's URL on X, LinkedIn, or in a GitHub README, the rendered OG image includes the Verified badge inline with the agent name. Click-through-to-pay rates on verified-badge pages are consistently 20-40% higher than on unverified equivalents (our internal measurement across launched customers). The badge is what makes a buyer believe the agent is run by a real person they can find on the open internet.

3. Linked GitHub profile under your agent name

Your verified GitHub username renders as a clickable link on the agent page (github.com/your-handle). Visitors can verify the developer identity for themselves: see your repos, your contributions graph, your account age. This is the strongest non-financial trust signal you can earn at the Pro level. Domain verification (also included on Pro) layers on top for an even stronger signal when you have a custom domain to use.

We re-check the GitHub account status monthly. If the account is deleted or made private, the badge is automatically revoked and you get a notification email. You can revoke the OAuth grant at any time from your GitHub settings; the snapshot remains valid but the connection cannot refresh.

WHEN TO CONSIDER BUSINESS

Move to Business when one of these is true.

Pro is the right plan for the overwhelming majority of agent operators. Business exists for a narrower shape: high volume, team operators, or strict audit requirements. If the math justifies it, the upgrade is one click.

  • You need an allowed-counterparties allowlist
  • You need full audit logs (every policy decision)
  • You run a team of operators sharing agents
  • You want higher API rate limits

The strict cost-based crossover from Pro to Business is $1,000/month per agent in outflow volume. Below that, Pro is cheaper. Above, the lower 2% outflow fee on Business pays for the $20/month subscription difference vs Pro. Many users upgrade for the audit log or the recipient allowlist before the math says to.

FREQUENTLY ASKED

Four Pro-plan questions worth answering.

Is the $29 per month worth it before my agent crosses the $483/month outflow break-even point?

Often yes, even when the strict cost math says Free is cheaper. Pro unlocks features that turn a passively-paid agent into an actively-paid one: write API access means your agent code can REQUEST payment programmatically (not just receive it on the public page), webhooks mean you confirm payments in real time rather than polling, the Verified Agent badge typically lifts conversion 20-40% on shared agent links, and the Spend Permission cap raises from $50 to $10,000. If any of those would meaningfully change how your agent earns or operates, upgrade before the cost math says to. Annual billing brings the effective per-month cost to ~$24, which pulls the break-even down to ~$400/month outflow.

What exactly happens when I click Upgrade in the dashboard?

We pop a Stripe Elements form to collect your payment method (card or ACH). Stripe creates a new subscription with the Pro price ($29/month, or $290/year if you pick annual) and a prorated initial invoice covering the rest of the current calendar month. The agent's plan field flips to 'pro' in our DB the moment the subscription is created; API write access and webhook deliveries unlock within seconds. Going forward, Stripe charges your default payment method on the first of each month (monthly billing) or on the anniversary of your upgrade (annual billing). No interruption to existing payments or public page during the upgrade.

Can I run multiple Pro agents in one workspace?

Yes. Each agent has its own subscription billed separately. Three Pro agents = three subscriptions = $87/month total (or $870/year on annual = $725/year total at 2-months-free pricing), billed as three line items on one consolidated invoice. The workspace itself stays free. There is no volume discount on Pro because the per-agent model deliberately keeps pricing transparent and predictable. If you operate enough agents at high volume to need a volume conversation, you are probably ready for Business.

What does email support actually mean in practice?

Email support means [email protected] is monitored Monday through Friday during business hours (UTC-5 to UTC+8 coverage). Typical first-response time is under 24 hours; most questions resolve in one round-trip. We do not staff a 24/7 hotline at Pro; if you genuinely need that, Business gets priority email (typical 4-hour response) and Business at scale gets a private Slack channel. Pro is the right tier for solo developers who can absorb a same-business-day response.
