GET /v1/balance

curl -H "Authorization: Bearer " https://powergpu.io/v1/balance

{ "object": "balance", "currency": "USD", "balance": 41.2183, "month_spend": 12.8402 }

POST /v1/instances

Deploy on a machine from /v1/offers. Body: machine_id (required), template, disk_gb, type (od | interruptible | res).

deploy

GET /v1/instances · GET /v1/instances/{id}

List active instances / fetch one (state, price, hostname, timestamps). Billing is settled at read time, so the numbers are per-second fresh.

POST /v1/instances/{id}/actions

-d '{"action":"stop"}'     # or start | destroy

DELETE /v1/instances/{id}

Alias for the destroy action. Instance disk is erased; attached volumes survive.

Errors

Status	code	Meaning
401	unauthorized	Missing or unknown Bearer key
404	not_found / no_route	Unknown instance or endpoint
409	deploy_failed / action_failed	Business rule said no — the message says why (balance, capacity, state)
422	missing_machine / bad_action	Request shape is wrong
429	rate_limited	Slow down; honour Retry-After
