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).
Example use cases
Pre-pipeline data quality check
“Before I run my ML pipeline, can you check these training records and tell me which fields are null or missing and how often?”
Customer data completeness audit
“I have a list of customer records and I want to know which fields like email or score are frequently null or missing — can you compute the null distribution across all of them?”
ETL data validation before ingestion
“Before loading these records into our database, can you analyze them and report the percentage of null or missing values per field so I know what to clean up first?”

Side effects

- 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
