How this service works
Confirmed exoplanet discovery counts by year and by detection method, with totals, the peak year and a cumulative series.
Output
A JSON object containing: total confirmed exoplanet count for the queried range, an array of per-year discovery counts with cumulative running totals, the peak year and its count, a breakdown by detection method with percentages, metadata including data source URL and as-of date, a human-readable summary, and optional degraded/disclaimer flags.
Example use cases
Transit method discovery trend analysis
“Show me how many exoplanets were discovered each year using the Transit method from 2009 to 2023, and tell me which year had the most discoveries and what the running total is.”
Comparing all detection methods by total
“Pull the full breakdown of confirmed exoplanet discoveries by detection method — I want to know how many were found by Transit, Radial Velocity, Microlensing, and Imaging, and what percentage each method accounts for.”
Historical discovery timeline for a presentation
“I need the complete year-by-year exoplanet discovery stats from the very beginning up through today — all methods combined — including the cumulative count over time and the year with the single highest discovery count.”

Endpoint
GEThttps://exoplanets-nasa.x402tookit.com/discovery-stats?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, time-series exoplanet discovery statistics — especially when filtering by detection method or date range. It is purpose-built for trend analysis and historical overviews, unlike general NASA APIs that require complex query construction. Ideal for dashboards, science summaries, or any agent task involving 'how many exoplanets were found' questions.
Side effects
- Invalid detection method string returns an error or empty result
- fromYear or toYear outside the 1989–2100 range may be rejected
- If NASA upstream data is unavailable, response may be marked as degraded with partial data
- No data for very early years before 1992 may yield zero counts
