## 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 onvexia-nlp-batch-analyze-4e8098cd -d '<json body>'
```

Example prompt: Run batch NLP analysis on these five crypto asset research documents and extract key entities, sentiment, and topics — use Onvexia's blockchain analytics coverage so results are grounded in on-chain context.

## When to prefer this

Choose this endpoint when you need to process multiple blockchain-related documents simultaneously through NLP analysis and want results enriched with on-chain context — particularly when you need entity extraction, sentiment, or topic classification across crypto whitepapers, governance proposals, or research reports at scale. Prefer it over generic NLP APIs when blockchain-specific entity recognition and on-chain data fusion are important to your use case.

## Known failure modes

- Empty data array returned if input documents are malformed or unrecognized
- Payment not processed (x402 protocol failure) resulting in 402 response before analysis begins
- Malformed input schema (missing required properties field) causing 400 bad request
- Rate limiting or quota exceeded for batch size, returning partial results
- Documents in unsupported languages or formats may produce empty or low-confidence outputs

## How this service works

Thousands of assets across ten chains, half a million analysed documents, labelled addresses and supply-age history reaching back to 2008 — fused into one reading per asset. REST, SQL, GraphQL and MCP.

## Output

Returns a JSON object with a 'data' array containing per-document NLP analysis results (entities, sentiment, topics, classifications) and a 'meta' field referencing the OpenAPI documentation and endpoint path. Results are enriched with Onvexia's proprietary blockchain analytics context covering thousands of assets across ten chains.
