What am I being billed for?
LLM tokens. We meter input and output tokens on every agent session and draw down your credit balance. There’s no per-seat, per-agent, or per-integration charge. Add a teammate, deploy a second agent, or wire up another MCP at no extra cost.
Why do input and output tokens have different prices?
Output tokens cost the model providers more to generate, so they cost more to bill. Input is what your prompt and the agent’s retrieved context consume; output is what the model produces in return. Most agent sessions are input-heavy, so the blended rate usually lands closer to the input price.
What does a typical agent session cost?
It depends on which model your agent runs. On Claude Opus, a 50,000-token session (40K input + 10K output) costs roughly $0.50. On Sonnet it’s about a third of that; on Haiku, less still. Heavier retrieval-augmented sessions on Opus land in the $1.00–$2.00 range. Early-adopter promotional credits cover hundreds of sessions before you ever top up.
What happens when my credit runs out?
With auto-reup enabled, the next call that would fail triggers a charge for your chosen pack ($5 to $1,000) and the session continues. Without auto-reup, calls return a clean402 Payment Required until you top up. You stay in control of the cap.
Can I cap my spend?
Yes. Auto-reup is opt-in. If you don’t enable it, you can’t spend more than your current credit balance.
Can I bring my own LLM API keys?
Not today. All LLM calls route through ArchAgents and tokens are billed centrally. If bring-your-own-key is a hard requirement for your use case, let us know.
How is Team different from Enterprise?
Team is sized for a focused portfolio: a handful of customer organizations, a manageable number of deployed agents, the published Team token rate. Enterprise lifts the scale caps and replaces the published rate with a negotiated contract. Talk to us about volumes, terms, and rollout support.
Do you offer volume discounts?
For sustained production usage we’ll work out a custom contract under Enterprise: annual term, fixed quota, or negotiated rate, depending on what fits. The Team rate-card stays published.
