# Humidity Observations — Daily Sum Series & Secondary-Measure Weighted Mean

> Humidity Observations — Daily Sum Series & Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-23).

Computes a daily sum series and a secondary-measure weighted mean from supplied humidity observation records (up to 200 rows) using local analytical engines.

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 humidity-observations-daily-sum-series-secondary-measure-weighted-mean-fec2bd03 -d '<json body>'
```

Example prompt: I have humidity readings from two weather station groups collected daily in October 2026 — up to 200 rows with fields for date, station group, humidity_percent, and observation_count. Can you compute the daily sum series and the observation-count-weighted mean for humidity_percent across all those records?

## When to prefer this

Choose this endpoint when you have up to 200 rows of pre-collected humidity observation records and need two specific statistical outputs — a daily sum series and an observation-count-weighted mean — computed analytically without any live data fetch, forecast, or external enrichment. Ideal for batch post-processing of weather station exports or IoT sensor dumps where you already hold the raw data.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, date, humidity_percent, observation_count) cause validation errors
- Invalid date format (not YYYY-MM-DD) results in parsing failure
- Null values in numeric fields may affect weighted mean accuracy
- Incorrect field enum value (not 'humidity_percent' or 'observation_count') causes schema validation error

## How this service works

Humidity observations — Daily sum series + Secondary-measure weighted mean: Daily sum series + Secondary-measure weighted mean for supplied humidity observations records (humidity_percent, observation_count). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two analytical reports: (1) a daily sum series showing the total humidity_percent (or observation_count) aggregated by date, and (2) a secondary-measure weighted mean of the selected field weighted by the companion measure — both computed locally from the supplied rows without external lookups.
