# Saylor Innovations Earth and Space Science – Geology at a Location

> Saylor Innovations Earth and Space Science – Geology at a Location is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).

Returns bedrock geology data (rock type, lithology, formation name, geologic age, and description) for any latitude/longitude coordinate worldwide, sourced from Macrostrat.

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-geology-at-a-location-fb29b0da
```

Example prompt: What's the bedrock geology at latitude 44.4280 and longitude -110.5885 — specifically the rock type, formation name, and geologic age?

## When to prefer this

Choose this endpoint when you need structured, machine-readable bedrock geology data (lithology, formation, age) for any specific coordinate worldwide. It draws on Macrostrat's globally comprehensive geologic map database, making it ideal for geospatial enrichment, environmental assessments, field planning, or educational geology queries. Prefer this over general search engines or GIS tools when you need a direct programmatic lookup keyed by lat/lon with structured output.

## Known failure modes

- No geologic data found for remote or unmapped coordinates (found: false)
- Invalid or out-of-range lat/lon values causing a bad request
- Location in ocean or polar region with no Macrostrat coverage
- Missing required lat or lon query parameters returns error
- Macrostrat upstream unavailability causing timeout or 5xx error

## How this service works

Geology at a Location: bedrock, rock type, age (Macrostrat). Geology at any location worldwide: the bedrock or surface geologic unit mapped at a latitude/longitude with rock type (lithology), formation name, geologic age in millions of years and period, description, elevation and the source geological survey map, plus units at other map scales. Macrostrat, CC BY 4.0.

## Output

A JSON object with a 'found' boolean, a 'bedrock' object containing the matched geologic unit (lithology, rock type, formation name, geologic age in Ma, period, description, elevation, and source map), and an array of 'units_at_other_map_scales' for alternative map scale representations of the same location.
