Questions

What counts as a request?

Every API call counts as one request, whether it succeeds or fails. WebSocket connections count as one request on connect.

Can I switch plans anytime?

Yes. Upgrades take effect immediately. Downgrades apply at the end of the current billing period.

What happens if I hit the rate limit?

You get a 429 response with a Retry-After header. Your requests are never dropped silently.

Do you take a cut on trades?

No. You pay your subscription and the exchange fees. Mithril does not add any fee on top of what the exchange charges.

How do I pay?

Card or USDC. No commitment — cancel anytime, no questions asked.

Is there a free trial for Builder?

The Free tier is effectively a permanent trial for read operations. Builder adds write operations (trading) — start when you need to place orders.
