One API to run EV charging — built for agents.
Charge point management, driver billing, and OCPI roaming through a single REST API. Deterministic JSON, scoped keys, and an LLM-native design — so your developers and your agents can ship.
Works with the AI stack your team already builds on
Three APIs. One platform.
The full e-mobility stack — operate hardware, bill drivers, and roam across networks — behind one base URL and one auth model.
CPMS API
The operator control plane. Manage chargers and connectors, push live OCPP commands, and run smart charging across your networks.
eMSP API
The e-mobility backend. Driver identity, authorization, sessions, and billing — so you ship charging apps without building the backend.
OCPI Roaming
Connect to roaming hubs and partner networks over standard OCPI. Locations, tariffs, sessions, and CDRs — normalized.
Designed for AI agents from the first endpoint.
Every endpoint ships with an LLM-ready spec, a deterministic response envelope, and scoped credentials — so an agent can discover, call, and verify without guesswork.
LLM-ready specs
Every endpoint exposes a clean, copy-paste spec block built for context windows. Point your agent at the docs and go.
Scoped keys
Mint keys against the cpms:* scope vocabulary — give an agent exactly the permissions it needs, read-only or full control.
Deterministic envelope
Every response is { data, success, timestamp }. Predictable to parse, easy to validate, safe to chain.
Live event stream
Subscribe to real-time charger, session, and status events — agents react the instant state changes.
The whole operator toolkit, one integration.
Real OCPP control, smart charging, billing, and analytics — the primitives a charging network actually runs on.
Live OCPP control
Remote start/stop, reboot, unlock, and change availability over OCPP 1.6 and 2.0.1 — straight from an API call.
Smart charging
Per-connector limits, composite schedules, and station-level load balancing with on-demand rebalance.
Tariffs & CDRs
Pricing, assignments, a full transaction ledger, and CSV export for reconciliation and payouts.
Analytics & SLA
Revenue, energy, sessions, utilization, and uptime rollups — scoped per network, ready for dashboards.
Webhooks & SSE
Signed webhook subscriptions plus a real-time SSE stream, with delivery history and retries.
Fraud & identity
Driver phone verification, fraud holds, and outstanding-balance checks before a session ever starts.
Your first call, in under a minute.
Authenticate with a single X-API-Key. Same resource model in every SDK.
A REST API you already know how to use.
Resource-oriented URLs, JSON everywhere, standard verbs, idempotency keys, and structured errors — across all three families.
