## 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-revisions-blockchain-analytics-coverage-feed-1b879f7c
```

Example prompt: Show me the most recent revisions to Onvexia's blockchain analytics coverage — pull up to 200 records so I can see what data changed and when.

## When to prefer this

Use this endpoint when you need to audit, monitor, or track changes to Onvexia's blockchain analytics coverage over time — particularly when building pipelines that depend on fresh data and need to detect when asset readings, labelled addresses, or document analyses have been revised. Prefer this over general asset-data endpoints when your goal is provenance or changelog inspection rather than live metric retrieval.

## Known failure modes

- Empty data array returned — indicates no revisions in the requested range, not a service error
- Limit parameter exceeds 200 — request may be rejected or capped
- Payment not processed via x402 — 402 response requiring USDC micropayment before data is returned
- Invalid query parameter type — non-string limit value may cause a 400 error
- Endpoint temporarily unavailable — standard 5xx response

## 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

A JSON object with a 'data' array of revision records (empty array if no rows in range, not an indicator of unsupported metrics) and a 'meta' object containing coverage and provenance information, including a link to the full OpenAPI spec at onvexia.com/openapi.json and the endpoint path '/v1/revisions'.
