OCPP 1.6J Compliant

The API for EV charging

OCPP infrastructure you can integrate in minutes, not months. Connect chargers, start sessions, and manage your fleet with a simple REST API.

# Start a charging session

curl -X POST .../chargers/CP001/remote-start \
  -H "X-API-Key: cap_live_sk_..." \
  -H "Content-Type: application/json" \
  -d '{"connectorId": 1, "idTag": "USER001"}'

# Response

{
  "success": true,
  "data": {
    "status": "Accepted",
    "chargerId": "CP001"
  }
}

Built for developers

Clean, predictable REST API. No SDKs required — just curl and go.
