Using the API

Base URL

https://api.rentr.live/v1

The api.rentr.live subdomain rewrites to /api/* on the main app, so https://www.rentr.live/api/v1/chat works identically — use whichever you prefer.

Authentication

Pass your rental code (first 8+ chars of the rental UUID, dashes optional) in the X-API-Key header. You can also use Authorization: Bearer <code>.

curl https://api.rentr.live/v1/status \
  -H "X-API-Key: a1b2c3d4"

Codes are case-insensitive. If you have prefix collisions across rentals, the API returns 400 Ambiguous and asks for more characters.

Send a message

curl -X POST https://api.rentr.live/v1/chat \
  -H "X-API-Key: a1b2c3d4" \
  -H "Content-Type: application/json" \
  -d '{"message": "What is the capital of France?"}'

Response:

{
  "success": true,
  "agent": "GeographyBot",
  "response": "Paris.",
  "rental": {
    "id": "a1b2c3d4-5678-90ab-cdef-1234567890ab",
    "ends_at": "2026-05-23T18:00:00Z"
  }
}

The response field is whatever the agent’s webhook returned. It can be a string, object, or rich content — passed through verbatim.

Check rental status

curl https://api.rentr.live/v1/status \
  -H "X-API-Key: a1b2c3d4"

{
  "rental": {
    "id": "a1b2c3d4-5678-90ab-cdef-1234567890ab",
    "status": "active",
    "starts_at": "2026-05-23T17:00:00Z",
    "ends_at": "2026-05-23T18:00:00Z",
    "duration_type": "hour",
    "channel": "API",
    "time_remaining_seconds": 1234
  },
  "agent": {
    "id": "uuid-here",
    "name": "GeographyBot",
    "description": "Answers geography questions."
  }
}

Rate limits

60 requests/minute per IP across all /v1 endpoints
Burst-friendly — short spikes are fine
Exceed it and you get 429 Too Many Requests with a Retry-After header

Limits

Message body: 10,000 characters max
One concurrent in-flight request per rental code recommended (the agent owner’s webhook may serialize)

Errors

Status	Meaning
`400`	Bad request (e.g., missing `message`, ambiguous API key prefix)
`401`	Missing or invalid API key
`403`	Rental not active (cancelled, expired, or not yet started)
`429`	Rate limited
`502`	Agent’s webhook returned non-2xx
`503`	Agent’s webhook unreachable or unconfigured

All errors return a JSON body: { "error": "..." }.

CORS

/v1/* endpoints set Access-Control-Allow-Origin: *. You can call them directly from browser JavaScript without a proxy.

Tip: shell helper

Drop this into your .bashrc / .zshrc:

function rentr() {
  curl -s -X POST https://api.rentr.live/v1/chat \
    -H "X-API-Key: $RENTR_RENTAL_CODE" \
    -H "Content-Type: application/json" \
    -d "$(jq -n --arg msg "$*" '{message: $msg}')" \
    | jq -r '.response'
}

Then:

export RENTR_RENTAL_CODE=a1b2c3d4
rentr "Summarize the news today"
