  title: Geo-Parity Childcare.json API
  version: 1.0.0
  description: 'Free, key-less JSON APIs behind geo-parity.com: purchasing power parity, fair global salaries, Schengen 90/180 compliance, cross-timezone meetings, contractor economics, freelance rates, tax-residency day counts, country comparison, cloud region latency, and a digital-nomad visa directory. All GET responses are cacheable; errors return { ok:false, code, message, example }. No key is required: anonymous callers get 1,500 requests/month per IP plus a 30/minute burst cap. An optional API key (Authorization: Bearer gp_live_..., created at /account) only raises those ceilings — responses are identical either way, and a key is metered per account rather than per key. Every response carries X-RateLimit-Limit / -Remaining / -Reset (the minute window) and X-Quota-Limit / -Remaining / -Reset (the calendar month, resetting on the 1st UTC); exceeding either returns 429 with Retry-After and code RATE_LIMITED (slow down) or QUOTA_EXCEEDED (allowance spent — retrying will not help). Figures are informational estimates, not financial/tax/legal advice. Machine discovery: /llms.txt and /.well-known/mcp.json; the same tools are also registered with the browser''s WebMCP ModelContext on every page, executing through /api/mcp.'
