## 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 macropulse-bls-series-us-labor-statistics-lookup-b45729ad
```

Example prompt: What are the latest BLS readings for CPI, core CPI, and unemployment — give me the current values and year-over-year changes for each?

## When to prefer this

Choose this endpoint when you need official, deterministic US macroeconomic data directly from the BLS — especially CPI, unemployment, wages, PPI, nonfarm payrolls, job openings, or ECI — with reliable year-over-year comparison baked in. Prefer this over LLM-generated macro summaries when accuracy, recency, and auditability matter. Use when you need up to 5 series in one call with no interpretation layer.

## Known failure modes

- Invalid or unrecognized series alias returns an error
- More than 5 series requested in a single call exceeds limit
- BLS API temporarily unavailable causes upstream timeout
- Unknown raw BLS series ID returns no data
- Payment of $0.02 USDC not fulfilled triggers 402 response

## How this service works

Official US labor statistics by series id, deterministic. Answers "what is US CPI/unemployment/wage growth right now and vs a year ago". Up to 5 BLS series per call — by alias (cpi, cpi-core, unemployment, nonfarm-payrolls, wages, job-openings, eci, ppi) or any raw BLS series id. Returns latest value, same-period year-ago value, computed YoY change and percent, and the last 13 observations, straight from the BLS API. No LLM, public domain.

## Output

For each requested series: the latest reported value, the same-period value from one year ago, the computed YoY absolute change and percent change, and the last 13 historical observations — sourced directly from the BLS API with no model-generated content.
