AGNT Agents pay for themselves
An agent signs up over HTTP, funds its balance with USDC on Base, and submits a bounded job. No browser or hosting-plan purchase is required for pay-as-you-go execution.
SANDBOX INFRASTRUCTURE FOR AGENTS
Run the task.
Keep the result.
Give your agent an isolated place to run Python, Node, and shell. Send files in, collect outputs, and set a hard limit on time and spend. The computer cleans itself up.
Start with $10 credit. No subscription required.

# Execute, collect, automatically destroyA separate guest kernel, non-root execution, offline networking, and a temporary workspace. Poll until ready, run your task, and export the result.

A VM for each task
Approved Python and Node runtimes inside Kata-backed VMs. Each environment has its own guest kernel, no network access, and no inherited account credentials.
Hard limits, clear billing
Choose the size and maximum lifetime before starting. Ready time is billed by the started minute, including idle time. Unused reservations are released after confirmed teardown.
Upload, execute, export
Bring in inputs, run commands, and download selected results through the API. Exported artifacts remain available for your plan’s retention window after the VM is gone.
Execution plans
Start with $10 prepaid credit. No subscription required: 6¢ per compute-minute. Regular users can choose a monthly plan.
| Plan | Monthly price | Included compute-minutes | Roughly | Extra minutes | Job deadline | Artifacts |
|---|---|---|---|---|---|---|
| Starter | $5 | 100 | 50 default jobs | 4¢/min | 15 minutes | 250 MB · 1 day |
| Pro | $15 | 400 | 200 default jobs | 3¢/min | 15 minutes | 1 GB · 7 days |
| Business | $39 | 1,200 | 600 default jobs | 2.5¢/min | 15 minutes | 3 GB · 30 days |
A compute-minute is one minute of a Small sandbox (1 vCPU, 1 GB RAM). Pay as you go: Small 6¢/min, Medium 12¢/min, Large 24¢/min. Every run rounds up to a whole minute, and a default job runs 2 minutes. Queue and provisioning time are not billed. Included minutes reset on day 1 UTC and do not roll over; purchased credit persists. Shared worker capacity is not reserved concurrency. AI inference is not included.
PLANS & USAGE
Simple, predictable pricing.
Compare the plans above. Runtime, artifact storage, and transfer allowances are pooled per account.
Create an account → add prepaid credit ($10 minimum) → run a job. No hosting purchase is required. Optional plans serve regular usage.

One started minute costs 1 compute-minute on Small, 2 on Medium and 4 on Large. Queued time is not billed. Ready time includes idle time.

What can run in a sandbox?
Python, Node, and shell in the approved Linux image. Guests start offline with an unprivileged user and a read-only base image. Arbitrary images, public inbound ports, snapshots, persistent volumes, and network-enabled profiles are not available.
How do I pay?
Start with $10 prepaid credit through Stripe or x402. Pay as you go at 6¢ per compute-minute, or choose a $5, $15 or $39 monthly plan. Each job shows its maximum authorization; unused reservations release after cleanup. No AI-model charges are included.
What are the file and isolation limits?
Upload and export files up to 8 MB. Scratch space is temporary and memory-backed: its logical 2/4/8 GB cap does not add to the guest’s 1/2/4 GB RAM budget. VMs run on shared infrastructure, not dedicated hosts. No isolation technology is an absolute security guarantee.
What happens when time or hosting runs out?
Managed jobs destroy their VM after execution and exports finish. New jobs default to a two-minute deadline and cannot exceed 15 minutes. Your command failing still consumes allocated time. Protected existing terms remain until their displayed expiry.
Give your agent its own computer.
Keep your workspace private. Bring back the result.
Already subscribe to AGNT?
Paid AGNT includes a monthly execution allowance: Personal 100 compute-minutes, Always-On 300, Business and Enterprise 600. Standalone and bundled allowances do not stack; the higher applicable allowance applies. Existing paid periods and transition allowances retain their terms until the date shown in your account. Any paid execution requires an explicit per-run spending cap.
