# NLRB Labor Petitions & ULP Charges Feed

> NLRB Labor Petitions & ULP Charges Feed is a paid API for AI agents from api.govparse.io, paid per call via x402, $25/call, status unknown (last checked 2026-09-15).

## 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 nlrb-labor-petitions-ulp-charges-feed-eda15dda
```

Example prompt: Pull the latest NLRB union representation petitions filed in California and New York since 2026-06-01 — show up to 500 rows and flag any Teamsters filings.

## When to prefer this

Choose this endpoint when you need a bulk, chronological feed of NLRB filings — especially for monitoring new union petitions across many employers at once, building labor-relations dashboards, or alerting PEO/staffing clients to emerging union activity. Prefer it over the single-employer NLRB search endpoint (also on api.govparse.io) when you need population-level scanning rather than a lookup for one specific employer. Best suited for compliance teams, labor counsel, and HR tech platforms that need fresh, filterable case data programmatically.

## Known failure modes

- Invalid state code returns empty result set or 400 validation error
- Unknown region code may return no rows rather than an error
- Very broad queries (no filters, category=all) may hit the 1000-row page cap and require cursor pagination
- Stale or replayed cursor token may return duplicate or out-of-order rows
- Upstream NLRB data lag may mean very recent filings (last 24-48 hours) are not yet indexed
- Payment failure (x402) returns 402 with no data

## How this service works

Which employers just drew a union representation petition? Bulk feed over NLRB cases, newest-first by filing date, defaulting to representation petitions (R cases): employer, case type, region, filing date, and unit size — a labor-relations moment for PEOs, staffing, and labor counsel. category widens to ULP charges or all cases. Flat rows, cursor-paginated up to 1000/page, filterable by state, region, or union. Observational records AS FILED — a petition is a filing, never an adjudication.

## Output

Flat rows of NLRB case records in newest-first filing-date order. Each row includes employer name, case number, case type, NLRB region, filing date, and bargaining unit size. Response also contains a next_cursor token for paginating subsequent pages (up to 1000 rows per page). Records reflect filings as submitted — not adjudicated outcomes.
