## 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 mining-share-aggregates-declared-column-projection-66558927 -d '<json body>'
```

Example prompt: Validate my mining share CSV — it has columns observation_id, observed_on, worker_id, accepted_shares, rejected_shares — and check that all worker_id values are either 'group-a' or 'group-b', numeric values are between 0 and 1000000, and no cell exceeds 500 characters; here's the CSV: 'record-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3'.

## When to prefer this

Choose this endpoint when you need structured, schema-contract validation of mining share aggregate CSV data specifically — particularly when you need to enforce declared column names, numeric bounds, and allowed categorical values for worker group identifiers. Ideal for pre-processing pipelines that must verify mining pool share data quality before downstream analytics.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows in CSV — validation may be truncated or rejected
- Invalid delimiter specified — parsing fails
- Cell exceeds max_cell_length — flagged as violation
- Numeric value outside minimum/maximum bounds — flagged as out-of-range
- Category value not in allowed_categories list — flagged as non-compliant
- Malformed CSV (unclosed quotes, inconsistent columns) — parse error returned

## How this service works

Mining share aggregates — Declared column projection: Declared column projection for Mining share aggregates. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV declared column projection report.

## Output

A declared column projection report indicating whether the submitted CSV conforms to the declared schema contract, including column presence, data type compliance, numeric range checks, allowed-category membership for categorical fields, cell length violations, and row-level validation results for up to 1000 rows.
