How this service works
OECD Composite Leading Indicator, which anticipates turning points of the business cycle 6-9 months ahead: value (100 = trend), monthly change and phase (expansion, downturn, slowdown, recovery) for major economies, G7 and OECD, or one country's series.
Output
Returns a JSON array of country objects, each with: country ISO code, country name, latest month (YYYY-MM), CLI value (100 = long-run trend), monthly change (percentage points), and business cycle phase (expansion, slowdown, contraction, recovery). Also includes source attribution and a note explaining phase definitions.
Example use cases
Business cycle dashboard for major economies
“Pull the latest OECD Composite Leading Indicators for all major economies and tell me which countries are currently in expansion, which are slowing down, and which are in recovery.”
Single-country CLI trend monitoring
“Get me the last 12 months of OECD leading indicator data for Germany — I want to see the CLI value and phase each month to understand how its business cycle has been evolving.”
G7 economic outlook assessment
“What's the current OECD Composite Leading Indicator for the G7 as a whole? I need the CLI value, monthly change, and business cycle phase to understand where the major economies are heading.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/oecd-leading-indicator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need forward-looking macroeconomic signals — the CLI is specifically designed to anticipate business cycle turning points 6–9 months ahead, making it more useful than lagging indicators like GDP for forecasting. Prefer this over raw OECD data downloads when you need a clean, parsed JSON response with phase labels already computed. Best for agents that need to classify economic regimes (expansion/slowdown/contraction/recovery) across multiple countries in a single call.
Side effects
- Invalid or unsupported country ISO code returns empty or error response
- Requesting too many months of history beyond available data range
- Malformed JSON body or missing required fields returns 400-level error
- Payment failure or insufficient USDC balance blocks the request
- Temporary OECD data source unavailability causes stale or missing data
