# Tempo API FAQ

Use these answers to choose the right Tempo API surface and understand what each hosted service does. For parameters, responses, and errors, use the [Tempo REST API reference](https://tempo.xyz/developers/docs/api#tempo-rest-api-endpoints).

## What is the Tempo API?

The Tempo API is Tempo's official hosted integration surface for stablecoin products. It provides indexed data, signed webhooks, funding and exchange quotes, fee sponsorship, read-only SQL, and JSON-RPC access without requiring you to operate the underlying infrastructure.

## How is the Tempo API different from Tempo RPC?

The Tempo API combines higher-level hosted services for indexed data, webhooks, quotes, sponsorship, and SQL. Tempo RPC is the lower-level [JSON-RPC interface](https://tempo.xyz/developers/docs/api/json-rpc) for querying chain state, calling contracts and precompiles, and submitting signed transactions. Use RPC when an Ethereum-compatible client needs direct chain access.

## Do I need a Tempo API key?

Most read endpoints work without credentials at the public rate limit. Use [MPP or an API key](https://tempo.xyz/developers/docs/api/authentication) for more throughput; webhook management requires an API key.

## How do I monitor a stablecoin payment?

Read the [transaction and receipt](https://tempo.xyz/developers/docs/api/transactions) to follow execution, then inspect its [transaction activities](https://tempo.xyz/developers/docs/api/activities#list-transaction-activities) to identify the stablecoin movement. Configure [webhooks](https://tempo.xyz/developers/docs/api/webhooks) for signed callbacks instead of polling, and review delivery history when you need to audit an attempt.

## Does the Tempo Funding API execute a transfer?

No. The [Funding API](https://tempo.xyz/developers/docs/api/funding) compares live quotes across supported chains and providers, but it does not execute a transfer. Execute the chosen transfer separately.

## Does the Tempo Exchange API submit a transaction?

No. The [Exchange API](https://tempo.xyz/developers/docs/api/exchange) creates a priced preview on Tempo's native stablecoin DEX and returns unsigned approval and swap calls. Sign and submit the returned calls to complete the exchange.

## Where do I manage Tempo API projects and keys?

Use [Tempo API Console](https://tempo.xyz/developers/docs/api/console) to create projects, switch between production and sandbox, issue API keys, monitor usage, and configure billing. Console access is currently invite-only.
