gov.osha-inspections

Search OSHA inspection records via the US Department of Labor Open Data Portal (~5M historical inspections). Filter by US state (2-letter), city, zip, or establishment-name substring (estabName, case-insensitive). Optional `filter` accepts raw OData-style clauses (joined with AND); `fields` selects columns; `sort` sorts (prefix with `-` for desc). Each row carries activity number, reporting id, establishment name + full site address, owner type/code, advance-notice flag, safety/health type, SIC + NAICS industry codes, open + close dates, host establishment number, union status. Backbone of workplace-safety + investigative-journalism agents.

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/gov/osha-inspections?state=xx&city=example&zip=12345&estabName=xx&fields=example&filter=example&sort=example&limit=25&offset=0'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/gov/osha-inspections?state=xx&city=example&zip=12345&estabName=xx&fields=example&filter=example&sort=example&limit=25&offset=0' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
