API
Ultra's blockchain REST API uses HTTP methods to communicate with network.
Endpoints are available for retrieving data, submitting transactions, and executing smart contracts.
It is recommended to use a package such as @ultraos/ultra-api-lib for handling transactions or more complex API calls.
Producer Endpoints
These endpoints all support /v1 API calls.

These are the public P2P endpoints provided by Ultra block producers for node operators to connect their nodes to the network. Add these as p2p-peer-address entries in your nodeos config.ini.
Main Network (Production)
| Block Producer | P2P Endpoint |
|---|---|
| EOSphere | peer1-ultra.eosphere.io:9877 |
| EOSphere | peer2-ultra.eosphere.io:9878 |
| EOS Sweden | p2p.ultra.eossweden.org:9776 |
| EOSUSA | ultra.eosusa.io:9881 |
| CryptoLions | p2p.ultra.cryptolions.io:9876 |

|---|---|
| EOS Sweden | p2p.testnet.ultra.eossweden.org:59776 |
| CryptoLions | p2p.ultra-testnet.cryptolions.io:9876 |
Example config.ini
p2p-peer-address = peer1-ultra.eosphere.io:9877
p2p-peer-address = peer2-ultra.eosphere.io:9878
p2p-peer-address = p2p.ultra.eossweden.org:9776
