Natur Halowerk Noise Level
x402
Natur Halowerk Noise Level is a paid API for AI agents from natur.halowerk.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-14).
Returns community sensor noise readings (LAeq, median, p10, p90) for outdoor sensors within a specified radius of a coordinate, sourced from Sensor.Community live data.

How this service works
Queries the Sensor.Community live area feed, keeps the newest noise reading per outdoor sensor within the requested radius, and returns nearest readings plus median, p10 and p90 LAeq. It never converts missing sensors into an estimated dB value. Community sensors are indicative rather than calibrated regulatory measurements; no day/night legal limit or property valuation is inferred.
Output
Returns an array of the nearest outdoor noise sensor readings (up to max_sensors), each with sensor ID, distance, and LAeq value, along with aggregate statistics: median LAeq, p10, and p90 across all sensors found. Sensors with missing values are excluded rather than estimated.
Example use cases
Neighborhood noise check before renting
“I'm considering renting an apartment near latitude 52.5200, longitude 13.4050 in Berlin — can you pull community noise sensor readings within 2 km and show me the median LAeq and the spread between p10 and p90?”
Urban noise mapping for a research project
“For my environmental study, get me up to 30 outdoor noise sensor readings from Sensor.Community within 10 km of latitude 48.8566, longitude 2.3522 in Paris and give me the statistical breakdown of the noise levels.”
Quiet zone verification for outdoor event planning
“We're planning an outdoor event near latitude 51.5074, longitude -0.1278 — can you check the noise readings from community sensors within 1 km and tell me the median and p90 LAeq so we can assess how loud the area typically is?”
Technical details
Endpoint
POSThttps://natur.halowerk.com/v1/noise-levelWhen to prefer
Choose this endpoint when you need real-time, community-sourced environmental noise statistics for a geographic area, particularly when statistical distribution (median, p10, p90) across multiple sensors matters more than a single point reading. Best suited for exploratory environmental assessments, neighborhood comparisons, or research aggregation where indicative rather than regulatory-grade measurements are sufficient. Not appropriate when legally calibrated noise measurements or day/night regulatory limit comparisons are required.
Side effects
- No sensors found within the requested radius — returns empty sensor list with no statistics
- Radius exceeds 25 km maximum or falls below 0.5 km — returns validation error
- Invalid latitude/longitude values outside allowed ranges — returns 400-level error
- Sensor.Community live feed temporarily unavailable — may return stale or empty data
- max_sensors capped at 30; requests for more are silently truncated to maximum
