WHAT HAPPENS WHEN YOU EXCEED YOUR PLAN?
Overage is soft — your agents never stop because of billing. Charges accrue and appear on your next invoice.
Free has no overage billing: past 5K requests, calls pass straight through — unmetered and unprotected — until you upgrade. Your agents are never blocked.

How the cap behaves
Alerts by default. Hard stops when you want them.
Alerts only — Solwyn never breaks your agents. You get notified; calls keep flowing.
Hard deny — over-budget calls stop in your process, before they reach the provider.
Stays denying — a Solwyn outage won't lift a hard cap that's already in effect.
Solwyn caps LLM calls made through the SDK. It is not a secret-scanning tool, a stolen-key firewall, or a cloud-infra waste platform.
Questions & answers.
Each LLM call instrumented by the Solwyn SDK counts as one request. Streaming calls count as one request.
Solwyn wraps any LLM client that follows standard API patterns. OpenAI, Anthropic, Google, Mistral, Cohere, and any OpenAI-compatible provider work out of the box. If you can call it from Python, Solwyn can wrap it.
Today, yes — the SDK is Python, installed with pip. More languages are on the roadmap.
Your agents keep running — Solwyn never interrupts service over billing. On paid plans, overage accrues automatically and appears on your next invoice. On Free, there's no overage billing: past 5K requests, calls pass straight through — unmetered and unprotected — until you upgrade.
Never. This is architecture, not a policy promise. The SDK wraps your client locally — LLM calls go directly from your app to the provider. Solwyn is never in the request path. Only metadata (token counts, costs, latency) reaches us.
No network hop. The budget check happens in your process against cached limits, and your call goes straight to the provider — Solwyn is never in the request path.
Your agents keep running. The SDK enforces cached budget limits locally and continues allowing requests. We fail open by default — Solwyn going down should never take your agents down with it. The one thing an outage never does is lift a hard cap that's already denying.
Start with the free tier — 5K requests/month with full protection, no credit card required. If you outgrow it, upgrade. And because Solwyn is a thin SDK wrapper, removing it takes one line of code — no migration, no lock-in, no cleanup.
Yes. Upgrades take effect immediately. Downgrades take effect at the start of the next billing cycle.
Yes. Annual billing saves you two months — Founder drops to $41/mo, Team to $124/mo, and Scale to $332/mo. Use the toggle on the pricing page to see annual rates.
Ship agents with brakes, not crossed fingers.
Wrap your client. Set a cap. When a loop, retry storm, or job crosses the limit, Solwyn denies the next request before it reaches the provider.
