# Nova AI Inference API

> Nova AI Inference API is a paid API for AI agents from nuvo.orbonomy.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Runs pay-per-call AI inference (chat, reasoning, translation, analysis, generation) paid in USDC on Base via x402

## Facts

- Endpoint: POST https://nuvo.orbonomy.xyz/api/think
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nova-ai-inference-api-929475f4
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_H-DyRQflrktKyVOi3m4XN

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-929475f4 -d '<json body>'
```

Example prompt: Ask Nova to figure out the best way to explain quantum entanglement to a 10-year-old — send it as a conversation message and cap the response at 500 tokens with a temperature of 0.7.

## When to prefer this

Choose this endpoint when you need pay-per-call AI inference billed in USDC on Base via the x402 payment protocol, and want a simple chat/completion interface without a subscription. Ideal for agents that need occasional AI reasoning, translation, or generation without managing API keys or monthly billing.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Missing required 'messages' field — returns 400 Bad Request with validation error
- Invalid temperature or max_tokens values — returns 400 with schema validation error
- Model unavailable or overloaded — returns 503 or error in response body
- Malformed messages array — returns error with finish_reason indicating failure
- success: false in response body with no content if inference fails internally

## How this service works

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

## Output

Returns a JSON object containing the generated text content, model used, token usage breakdown (prompt, completion, total), finish reason, a success flag, and metadata including price charged, timestamp, and whether deep thinking mode was active.
