# Safe Public Inputs

> Use public-chain context with Nova APIs. Keep wallet secrets out of every request.

Nova APIs are built around public blockchain context: wallet addresses, token mints, transaction signatures, and public app URLs.

Send one of those identifiers and Nova returns security context, token data, wallet intelligence, or market signals without needing private wallet material.

## Good Inputs

Use these for normal analysis:

* Public wallet addresses
* Token mints
* Transaction signatures
* Public app or dapp URLs
* Plain-language questions

## Never Send Wallet Secrets

Nova does not need:

* Seed phrases or recovery phrases
* Private keys
* Mnemonics
* Passcodes
* Backup codes
* Signing requests or signing payloads

Wallet approvals and signing belong in the wallet app, not in an API request.

## Before You Act

Nova can explain risk, context, and next steps. When a flow can move funds, the wallet should show the transaction details and approval step before anything is signed.

Read the approval carefully before signing.

## Playground

Paste a public address or mint and inspect the response. Nova handles rate limits, request caps, and abuse protection at the platform layer.
