How does the free tier work?

Every key starts on Free: 1,000 credits a month, 30 requests a minute, no card. Free covers market data, fundamentals, and public filings, and stops at its monthly grant instead of billing you.

When do I move from Free to a paid plan?

When you need more than 1,000 credits a month, a higher rate limit, or data beyond the Free set. Starter is $99/mo for 250,000 credits, Pro $499/mo for 2,000,000, and Expert $999/mo for 11,200,000. Annual billing is two months free compared with paying monthly, and paid plans can run into metered overage past their grant.

Can I bring my own LLM?

Yes. Register Wealthnow as an MCP server and pull the tool surface into any Claude, GPT, or open-model agent. You're paying for the data, not the model.

Does the API support live trading?

No. The API returns market data and analytics only. It places no orders.

What's in the Enterprise tier?

Everything in Expert, plus custom limits, invoicing and support.

How do I get support?

Free: community + docs. Paid plans: email and a shared Slack channel. Enterprise: a named engineer who knows your integration and joins your incidents.
