# FAQ

> Short answers to common questions.


## Is the API free?

Yes. Keys are free, with 600 requests a minute and 250,000 a day each. Write to `team@payday.direct` for more.

## Do I need to sign in?

Not to read data. Sign in with X to list and revoke your keys, and to make a key that launches coins.

## Do I need a wallet?

Not to read. To launch, the user's wallet signs (Solana) or sends (EVM) the launch and pays for it.

## Can a key move money?

No. No key can move funds or sign anything. A launch key only builds transactions for a wallet to sign.

## How fresh is the data?

A 15 second snapshot; the registry finds new coins in about 3 seconds.

## Why is a coin I know missing?

It may be seconds old (ask again shortly), hidden until its fee split confirms, or its account opted out of Payday.

## Can I call it from a web page?

The API answers any origin (CORS), but a key in a web page can be read by anyone who opens it. Call it from your server.

## Is there an SDK?

Not yet. The [OpenAPI spec](https://payday.direct/api/v1/openapi.json) generates a typed client in most languages (openapi-generator, openapi-typescript, oapi-codegen).
