# Species and Biodiversity – Most-Recorded Species Near a Location

> Species and Biodiversity – Most-Recorded Species Near a Location is a paid API for AI agents from biodiversity.x402tookit.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-29).

Returns the most-observed species (birds, mammals, plants, fungi, and more) within a radius of a given lat/lon, with observation counts.

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 species-and-biodiversity-most-recorded-species-near-a-location-7a1fdd38
```

Example prompt: What are the most-recorded species within 20 km of coordinates 51.5074, -0.1278? I'm especially interested in birds and mammals.

## When to prefer this

Use this endpoint when you need a ranked, observation-count-backed list of species recorded near a specific geographic point. It is ideal for biodiversity surveys, wildlife education, environmental baselines, and nature tourism planning. Prefer it over a species-name search endpoint when you know the location but not the species, and over a species-profile endpoint when you want a community-level overview rather than detail on one taxon.

## Known failure modes

- Missing required lat or lon parameters returns a validation error
- Radius outside 1–50 km range may be rejected or clamped
- Coordinates in remote areas with few GBIF records may return an empty or very short species list
- Invalid group filter string may return an error or fall back to 'all'
- Service degradation flagged in the 'degraded' response field when upstream GBIF data is partially unavailable

## How this service works

Most-recorded species within a radius of a location (birds, mammals, plants and more), with observation counts.

## Output

A ranked list of the most-observed species near the given coordinates, each with common name, scientific name, family, taxon key, and observation record count. Also includes total records in the area, data source, source URL, attribution, a plain-English summary, and optional degraded/disclaimer flags.
