# ARC Endpoints

ARC is the successor of mAPI, the merchant API.

The URL of TAAL's mainnet ARC API is: <https://arc.taal.com/v1>

For instance the policy could be fetched using the following `curl` command

```powershell
curl --location 'https://arc.taal.com/v1/policy' \
--header 'Authorization: <API Key>'
```

A complete description of ARC API endpoints can be found under the following link: <https://bitcoin-sv.github.io/arc/api.html>.

It is recommended to use the BIP-239 transaction format for submitting transactions to ARC.
