ArvoCode API.

Programmatic access to the Arvo model family.

Base URL

https://platform.openartemis.com/v1

Authentication

Bearer token over HTTPS.

Authenticate every request by passing your API key as a Bearer token in the Authorization header. Keys are scoped per account and rotatable from the dashboard.

Authorization: Bearer <YOUR_API_KEY>

request.shcurl

curl https://platform.openartemis.com/v1/messages \
  -H "Authorization: Bearer $OPENARTEMIS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "arvo-fern-2",
    "messages": [
      { "role": "user", "content": "Hello, Arvo." }
    ]
  }'

Models & Pricing

Frontier quality. Below market.

Model ID	Display name	Context	Input /1M	Output /1M	Best for
arvo-kin-1	Arvo Kin	1B	$0.10	$0.30	Fast tasks, high volume
arvo-fern-2	Arvo Fern	100B	$0.40	$1.20	Balanced workloads
arvo-stoic-1	Arvo Stoic	1T	$1.00	$3.00	Frontier-grade tasks

Positioning

API pricing is intentionally positioned below prevailing frontier market rates. HA’s compute efficiency compounds directly into unit economics — so we pass it on.
