# OSF Environmental Data Search

> OSF Environmental Data Search is a paid API for AI agents from api.osf-master-server.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Searches US environmental datasets by keyword across USGS, NOAA, GBIF, FEMA, and EPA, returning location, measurements, dates, and provenance URLs per match.

## Facts

- Endpoint: GET https://api.osf-master-server.com/x402/environment/data/:query
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 osf-environmental-data-search-533c6df8
```

Example prompt: Can you pull environmental data about Colorado River streamflow — I need water quality measurements, locations, and dates with source links?

## When to prefer this

Choose this endpoint when you need to search across multiple US environmental and geospatial data sources simultaneously with a single keyword query, especially when you need provenance-stamped results linking back to authoritative government sources like USGS, NOAA, GBIF, FEMA, or EPA. Ideal for climate, environmental monitoring, ecological research, hazard tracking, and regulatory compliance use cases.

## Known failure modes

- No matching records found for the given keyword — returns empty results
- Overly broad keyword returns too many unrelated records across data sources
- Keyword too specific or misspelled — returns zero matches
- One or more upstream data sources (USGS, NOAA, etc.) temporarily unavailable
- Rate limiting or payment failure for the $0.05 per call charge

## How this service works

Search US environmental data by keyword: water quality and streamflow (USGS), weather, tides and space weather (NOAA), volcanic and hazard alerts, species occurrences (GBIF), disaster declarations (FEMA), and facility compliance (EPA). Returns location, measurement, dates, and a provenance URL per match. For climate, environmental, and geospatial agents.

## Output

Returns a list of matching records from across USGS, NOAA, GBIF, FEMA, and EPA datasets, each including location, measurement values, relevant dates, and a provenance URL linking back to the original authoritative source.
