# NASA Media Library Collection Stats

> NASA Media Library Collection Stats is a paid API for AI agents from nasa-media.x402tookit.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-11-02).

Count NASA media library items matching a query, broken down by year or by NASA center, using total hit counts from the NASA Image and Video Library API.

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 nasa-media-library-collection-stats-45c2df87
```

Example prompt: How many NASA images and videos exist for 'space shuttle', broken down by year from 1970 to 2011?

## When to prefer this

Use this endpoint when you need aggregate statistics or trend analysis over NASA's media library — specifically hit counts grouped by year or center — rather than fetching actual media items or metadata. Prefer this over the search endpoint when the goal is counting, comparing volumes, or identifying peak periods of coverage for a topic.

## Known failure modes

- Missing required 'q' parameter returns an error
- Query exceeding 100 characters may be rejected
- Invalid media_type value (not image/video/audio) causes an error
- year_end more than 15 years after year_start may be rejected
- group_by value other than 'year' or 'center' causes an error
- NASA upstream API downtime may result in degraded or null bucket data

## How this service works

Count NASA library items matching a query, broken down by year or by center, using the API's total hit counts.

## Output

Returns total hit count, bucketed counts (by year or center), share percentages per bucket, the peak bucket (label + hits), a plain-language summary, the original query, media type filter applied, data source URL, and optional degraded/disclaimer flags.
