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 x402-factory-economic-dashboard-delta-6e7ac793
```

Example prompt: Give me only the US economic observations that have been printed or revised since my last poll — use my cursor 'abc123xyz' to fetch the delta and return the changed count and next cursor.

## When to prefer this

Choose this endpoint when you need to efficiently monitor US economic data for new prints or revisions without re-fetching the entire dashboard. It is ideal for polling loops, trading bots, or alert systems that need incremental updates rather than full snapshots. Prefer the free sibling /v1/econ/dashboard for an initial full load, then switch to this delta endpoint for ongoing incremental sync using the returned cursor.

## Known failure modes

- Invalid or expired cursor returns an error or resets to bootstrap behavior
- Omitting 'since' bootstraps a new cursor rather than fetching historical deltas (expected behavior)
- No changes since last cursor returns empty rows array with changed_count of 0 and a new next_cursor
- Network timeout or server error on $0.015 USDC paid request with no refund
- Cursor string truncated or malformed (minLength 4, maxLength 300) returns validation error

## How this service works

Only the econ observations printed or revised changed since your cursor (delta o — Keyset delta of /v1/econ/dashboard: pass since=<next_cursor from your last call> and get only the econ observations printed or revised added or changed after it, plus changed_count and a new next_cursor. Omit since once to bootstrap. Cursors are stable across restarts. Poll the free sibling…

## Output

Returns a JSON object with a 'rows' array of changed economic observations (each with series name, observation date, latest value, latest vintage, first value, and a boolean revision flag), a 'changed_count' integer, an 'as_of' timestamp, and a 'next_cursor' string for the subsequent incremental poll.
