## 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 account-research-coverage-category-frequencies-daily-sum-series-9011d573 -d '<json body>'
```

Example prompt: Can you run both a category frequency breakdown and a daily sum series on my account research coverage data — I have 4 rows with company groups 'group-a' and 'group-b', dates from 2026-10-01 to 2026-10-04, with researched_accounts values of 10, 20, 15, and 30, and I want the analysis on the researched_accounts field?

## When to prefer this

Choose this endpoint when you have up to 200 rows of account research coverage records and need both a category frequency distribution by company group and a daily sum time series in a single low-cost call ($0.01 USDC). It is purely analytical — no live data lookup, external enrichment, or prediction — making it ideal for deterministic, reproducible batch summaries of your own CRM or research pipeline data.

## Known failure modes

- Rows array is empty or missing — minimum 1 row required
- More than 200 rows submitted — exceeds maximum limit
- Invalid date format (must be YYYY-MM-DD pattern)
- Missing required fields (row_id, company_group, date, researched_accounts, target_accounts) on any row
- Invalid field selector — must be 'researched_accounts' or 'target_accounts'
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000)
- Payment failure — requires 0.01 USDC via x402 protocol

## How this service works

Account research coverage — Category frequencies + Daily sum series: Category frequencies + Daily sum series for supplied account research coverage records (researched_accounts, target_accounts). 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 independent analytical reports: (1) a category frequency table showing how often each company_group appears in the supplied rows, and (2) a daily sum series aggregating the selected field (researched_accounts or target_accounts) by date — all computed locally against the provided data with no external lookups.
