  ]
}

Field notes:

  • id is provider/name — pass it as model in chat completions, and use it (slash included, unencoded) in the detail route GET /v1/models/{provider}/{name} — e.g. GET https://api.deva.me/v1/models/openai/gpt-4o.
  • pricing.prompt / pricing.completion are decimal strings in USD per token (multiply by 1,000,000 for $/1M tokens). prompt_karma / completion_karma are the karma equivalents (USD × 1000), also per token.
  • description, input_modalities, and output_modalities are nullable. Modality values: text, image, audio, file, video.
  • The detail route returns the same model object flattened at the top level plus pricing_version / last_updated.

POST /v1/chat/completions

OpenAI-compatible chat completions across every model in the catalog — this is the canonical path. The official OpenAI SDKs work as-is with base_url / baseURL set to https://api.deva.me/v1 (see the quickstart).

Request: the standard OpenAI body — model (an id from /v1/models), messages, and optional stream, max_tokens, temperature, tools, etc.

curl https://api.deva.me/v1/chat/completions \
  -H "Authorization: Bearer deva_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-opus-4-7",
    "messages": [{"role": "user", "content": "Hello!"}],
    "stream": false
  }'

Response: the standard OpenAI envelope, with Deva's billing extension on usage:

{
  "usage": {
    "prompt_tokens": 9,
    "completion_tokens": 12,
    "total_tokens": 21,
    "cost": 0.000345,
    "deva": { "karma_cost": 1, "karma_balance": 4999 }
  }
}
  • usage.cost — USD cost of the call (mirrors OpenRouter's usage.cost).
  • usage.deva.karma_cost / usage.deva.karma_balance — karma charged and remaining balance.

Billing surfaces:

  • Non-streaming: response headers X-Deva-Karma-Cost, X-Deva-Cost-USD, and X-Deva-Karma-Balance are set alongside usage.
  • Streaming ("stream": true): Server-Sent Events; headers are sent before the cost is known, so the final SSE chunk carries the usage object (including usage.deva).

Errors:

  • 402 — insufficient karma: an OpenAI-style error envelope with type insufficient_quota. Top up karma and retry. (Distinct from the x402 USDC payment challenges described in x402-payments.md.)
  • 400 — invalid request (unknown model, malformed messages).
