Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-earth-and-space-science-newly-discovered-038d565c
```

Example prompt: Can you pull the 50 most recently confirmed exoplanets discovered by the Transit method from the NASA Exoplanet Archive, including their size, mass, and host star info?

## When to prefer this

Choose this endpoint when you need structured, up-to-date data on newly confirmed exoplanets sourced from the authoritative NASA Exoplanet Archive, especially when filtering by discovery method (Transit, Microlensing, Radial Velocity) or needing aggregate counts alongside individual planet details. Prefer this over general web search when you need machine-readable planetary parameters like size, mass, and orbital data.

## Known failure modes

- Invalid discovery method filter value returns no results or an error
- Limit parameter outside 1-100 range may be rejected or clamped
- NASA Exoplanet Archive data lag means very recent discoveries may not yet appear
- Empty planet array returned if no planets confirmed in the past year matching the filter

## How this service works

Newly Discovered Exoplanets (NASA Exoplanet Archive). Newly discovered exoplanets (NASA Exoplanet Archive): confirmed planets published since last year, newest first, with discovery method, size, mass, orbit and host star, counts by discovery method, and the total number of confirmed exoplanets. Filter by method (Transit, Microlensing, Radial Velocity). Public domain.

## Output

Returns a JSON object with a boolean 'found' field, an array of planet objects (each with discovery method, size, mass, orbital parameters, and host star info), method-level discovery counts, and the total number of confirmed exoplanets in the NASA archive.
