# Nova AI Inference API

> Nova AI Inference API is a paid API for AI agents from ova.orbonomy.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Pay-per-call AI inference endpoint supporting chat, reasoning, translation, analysis, and generation, billed per call in USDC on Base.

## Facts

- Endpoint: POST https://ova.orbonomy.xyz/api/think
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nova-ai-inference-api-13362cae
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_hU6l-N_oT8lf8W9Z21HgK

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nova-ai-inference-api-13362cae -d '<json body>'
```

Example prompt: Using Nova's pay-per-call inference, send this message to the AI: 'Explain the pros and cons of nuclear energy in three bullet points' — keep the response under 300 tokens and use a temperature of 0.7.

## When to prefer this

Prefer this endpoint when you need one-off or low-frequency AI inference without a subscription, want to pay per call in USDC on Base, or are building an agent that needs LLM reasoning, translation, or generation as a composable step in a crypto-native workflow.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required response
- Malformed messages array or missing required field — 400 Bad Request
- Model overloaded or unavailable — 503 Service Unavailable
- Token limit exceeded — response truncated with finish_reason: length
- Invalid temperature or max_tokens values — 422 Unprocessable Entity

## How this service works

Pay-per-call AI inference. Chat, reason, translate, analyze, generate. USDC on Base.

## Output

Returns a JSON object with a success flag, a data object containing the generated text content, model name, finish reason, and token usage breakdown (prompt, completion, total), plus a meta object with model, price, endpoint, timestamp, and whether deep thinking was enabled.
