First event in under five minutes

Ondari turns AI activity into economic events. You report what happened — provider, model, usage. Ondari resolves the pricing, calculates the cost, and explains it.

Quickstart

1. Create an account and an API key in the dashboard.
2. Send one event after an LLM call, tool use, or compute action.
3. Watch the cost appear in your dashboard — priced and explained.

curl -X POST https://ondari.dev/api/ingest \
  -H "Content-Type: application/json" \
  -H "x-api-key: ab_..." \
  -d '{
    "idempotency_key": "run-42-call-07",
    "provider": "anthropic",
    "model": "claude-sonnet-4.5",
    "agentId": "research-agent",
    "inputTokens": 12450,
    "outputTokens": 2840
  }'

Canonical event

You never send a cost. Ondari determines the economic value server-side from versioned pricing.

{
  "idempotency_key": "run-42-call-07",
  "provider": "anthropic",
  "model": "claude-sonnet-4.5",
  "agentId": "research-agent",
  "workflowId": "weekly-research",
  "taskId": "task_456",
  "environment": "production",
  "inputTokens": 12450,
  "outputTokens": 2840,

  "status": "success",
  "source": "sdk"
}

Field	Type	Notes
idempotency_key	string	Required. Unique per event; replay-safe.
provider	string	Required. e.g. openai, anthropic, e2b.
model	string	Exact model id, e.g. claude-sonnet-4.5.
agentId	string	The agent that produced the event.
workflowId / taskId	string	For workflow & task attribution.
environment	string	e.g. production, staging.
inputTokens / outputTokens	number	Token counts. Ondari prices them.
cachedInputTokens / reasoningTokens	number	Optional token breakdowns.
latencyMs	number	Optional latency in milliseconds.
status	string	Optional. e.g. success, error.
source	string	Optional. e.g. sdk, api, manual.

Unknown models are never dropped

If a model has no known pricing yet, the event is accepted and markedunpriced— never silently zero. When pricing is discovered, costs are backfilled automatically. Unknown cost is not zero cost.
