Argosvix

Frequently asked

The main things worth knowing before you decide. More in the docs.

Can I verify my Cursor or Claude.ai bill / token usage?

No — Cursor, Claude.ai, ChatGPT, and similar subscription tools call LLM APIs server-side, so a third-party tool can't observe them. Argosvix observes your own application when you call OpenAI / Anthropic / Gemini / Mistral SDKs directly.

Where is my data stored?

Cloudflare's Tokyo region (D1). Prompt and completion plaintext is AES-256-GCM encrypted. Per-record deletion and shortened retention are both controllable from your account.

How is this different from Langfuse / Helicone?

Three things. First, more than half of the 87 MCP tools are write/operation tools so Claude / Cursor / Codex CLI can actually change things — most tools in this space lean read-only, and we put writes front and center. Second, a flat $13/mo for up to 1,000,000 calls — most competitors move to usage-based pricing after tens of thousands of events. Third, recording, alerts, prompt management, eval, safety classification, and MCP are all in one contract.

Can I self-host?

Argosvix is currently cloud (SaaS) only. A self-hosted edition is under consideration, but there is no committed timeline. If you need it, tell us at hello@argosvix.com.

What are the Free plan limits?

50,000 calls / month, 30-day retention, 3 alerts, 1,000-record CSV export, 1 seat. Pro plan ships with a 7-day free trial.

Can I keep my code private?

The SDK is a public package on npm (@argosvix/sdk) and PyPI (argosvix). Your code and prompts are only sent to your Argosvix dashboard — never published or shared.

What payment methods are accepted?

Credit cards (Visa / Mastercard / JCB credit / American Express). Payments are processed by Stripe and invoices are available in your dashboard. Note that JCB debit cards are not supported due to a Stripe limitation.

Which languages / SDKs are supported?

Official SDKs for TypeScript / JavaScript (@argosvix/sdk on npm) and Python (argosvix on PyPI). You can also POST to the REST API directly without an SDK.

Which clients support MCP?

Any MCP-capable client — Claude Desktop, Cursor, Codex CLI, and others. Both stdio and HTTP transports are supported.

What happens if I exceed the monthly limit?

Once you hit the limit, new records are rejected until the start of the next month (senders receive an error, but the SDK is designed to never break your application on a failed record). We email you at 80% and 100% of usage, and the dashboard shows a banner when the limit is reached. There is no surprise metered billing.

How do trials and cancellation work?

Pro comes with a 7-day free trial; cancel within the trial and you won't be charged. You can cancel anytime from the billing screen and keep access until the end of the current billing period.
