> Nova AI Inference API — Batch Endpoint 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).

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-batch-endpoint-61f96fb9 -d '<json body>'
```

Example prompt: I have three tasks I need done at once: summarize this article, translate this paragraph to Spanish, and classify this customer review as positive or negative — can you send all three to Nova as a batch using the default model and run them concurrently?

## When to prefer this

Choose this endpoint when you need to run multiple AI inference tasks (chat, translation, analysis, generation, reasoning) in a single network round-trip and want pay-per-call USDC billing on Base via x402 — especially when throughput or latency across many items matters and you want aggregate usage tracking.

## Known failure modes

- Invalid or missing items array returns a 400 validation error
- Model identifier not recognized returns an error referencing an unsupported model
- Insufficient USDC balance or failed x402 payment causes a 402 Payment Required response
- Empty items array may return zero results or a validation error
- Concurrent flag conflicts with backend limits may cause partial failures or timeouts
- Malformed item objects within the array may cause individual result failures while others succeed

## How this service works

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

## Output

An array of result objects, one per batch item, each containing an id, the output text, and token usage stats, plus an aggregate total_usage and items_processed count, wrapped in a success envelope.
