## 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 delx-commerce-null-distribution-analyzer-83cbf3c0 -d '<json body>'
```

Example prompt: Can you analyze these records and tell me which fields have null or missing values and what percentage of records are affected for each field?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call null and missing value profiling tool with no signup friction, especially in agent workflows where data quality checks are a preprocessing step before storage or ML pipelines. Ideal when you want verifiable, per-field null statistics delivered cheaply at $0.003 USDC per call via x402 on Base or Solana.

## Known failure modes

- Empty or malformed records array returns an error or empty field map
- Non-array input for records field causes schema validation failure
- Payment not delivered via x402 protocol results in 402 Payment Required response
- Extremely large record arrays may time out or exceed payload limits

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with per-field statistics including the percentage of non-null values and the count of null or missing entries, along with the total record count and a schema identifier (e.g. delx/util-null-distribution/v1).
