  • An illustration, not a measurement: these four lines are the ones on every real receipt.
  • On your own API keys, your provider bills the Model usage line instead.

Top-up rates

Included usage is drawn first. Without a plan, or once it runs out, usage draws from your top-up credit at these rates.

Agent work
$0.020 per active work minuteMeasured by the second: Free wait time is $0.00.
Agent memory (Beta)
$0.0000840 per GB-hourAgent short-term memory, including work histories, execution trajectories, and artifacts. Metered hourly: about $0.0613 per GB-month. Beta pricing, subject to change with advance notice.
Model usage
The listed catalog priceNo markup on top of the upstream listing price: text, image, video, and voice models alike. See every model and price
Top-up credit
$10 minimum per top-up5.5% processing fee (minimum $0.80) · valid 12 months.

On the free plan, topping up lets you run models through HarnessRouter at the same listed prices, with no provider key needed.

Fine print
  • Listed price means the price shown in our model catalog for the model and the upstream provider serving your request. It follows that provider’s standard published API price, and we add no markup on top of it.
  • We add no markup to model prices. Routing your own API keys carries no fee up to $25k a month of Model usage at listed prices; above that volume a separate routing fee of 5% of that value applies and appears as its own line on the receipt.
  • Longest single task on the free plan: 30 minutes, or 1 hour once you top up. Paid plans run longer tasks. current limits are shown in the console.
  • No separate data-transfer fee for normal app use; fair-use limits in our Terms apply.

Prices, rates, and included usage shown here are current and may change in the future. Checkout shows the final price, currency, renewal timing, and usage terms for each purchase.

Billing questions

What counts as agent work?

Executing a step or a tool: running code, editing files, calling an API, browsing. Waiting for a model response, waiting for you, waiting in a queue, and platform retries are Free wait time, shown on every receipt at $0.00 and split into model, user, and platform wait. Overlapping steps are measured once, by elapsed time, not once per process. Everything is measured by the second and can be recomputed from your retained task records.

What is data retention?

Each task’s step-by-step record: what the agent did, which tools it called, what it produced, and how long each step took, next to the cost breakdown. On the free plan that record is kept for 7 days and then deleted; on every paid plan it is kept for as long as your workspace exists. Receipts and per-task totals stay in Billing regardless. Data retention is separate from agent memory: the files your tasks create count toward agent memory, the record of how they were made does not.

What is tracing?

The console view of each task’s retained record, step by step. It is included with Scale, and available on other plans as a $50 per month add-on. All events are included during beta; pricing may change at general availability, with advance notice. The cost breakdown of every task (Model usage, Agent work, Free wait time, Task total) is free on every plan.

Which models can I use, and what do they cost?

Every model the router can reach, from Anthropic, OpenAI, Google, DeepSeek, Alibaba Qwen, Z.ai, Mistral, Moonshot AI, and more, billed at its listed catalog price with no markup on top of the upstream listing price. Bring your own keys and your provider bills you directly instead. The catalog lists each model with its current price per million tokens. See every model and price

Is the free plan really free?

Yes: no card and no expiry. Explore the console, create workspaces, and configure agents at no cost. Running tasks draws from top-up credit, and your workspaces and data stay untouched whatever your balance.

Why subscribe instead of just topping up?

Below about $20 of usage a month, topping up costs less overall, because a plan’s included usage would go partly unused; top-up credit stays valid for 12 months. From about $20 a month, a plan costs less on every rate: no processing fee (top-ups carry 5.5%, minimum $0.80), Agent work from $0.014 per active work minute instead of $0.020, longer-running tasks, and unlimited data retention instead of 7 days. Every dollar of the plan is usage.

What happens when included usage runs out?

Included usage resets at the start of each billing month and does not carry over. Billing shows how much you have left at any time. When it runs out, you choose: keep going at the same listed rates from your top-up credit, or stop until the next month. Every task shows its Model usage, Agent work, Free wait time, and Task total, so nothing on the bill is a surprise.

What happens if I cancel?

Your plan runs to the end of the billing month, then you drop back to the free plan; usage already incurred is still billed, and no new plan charges follow. Your workspaces and data stay with your account on the free plan, and you can export or delete them yourself at any time. Top-up credit keeps its original 12-month validity.

How do payments work?

Self-serve plans and top-ups are card-only. Invoicing and bank transfer are available on enterprise agreements: talk to us.
