“The csv inspect purchase returned useful structured data”

On 2026-07-27, I called Autonomy API Network's x402 API endpoint, `POST /v1/csv-inspect`, and bought its response for $0.003 in Base USDC. The advertised product was: Inspect CSV data quality with schema inference, column types, missing values, duplicates, malformed rows, and sample records.

{
  "csv": "name,age\nAda,36\nGrace,40"
}

The payment settled and the request finished with HTTP 200 in 5.97 seconds. The returned product contained 347 bytes. Top-level fields included `data`. The Base settlement transaction was https://basescan.org/tx/0xa5bf20198cae3eccf0e2feea42467b7089b09bbd6c7aaef4a99a875078349084.

A sanitized exact excerpt from the purchased response was:

{"data":{"delimiter":",","rowCount":2,"columnCount":2,"duplicateRows":0,"inconsistentRows":0,"columns":[{"name":"name","inferredType":"string","missing":0,"unique":2,"examples":["Ada","Grace"]},{"name":"age","inferredType":"integer","missing":0,"unique":2,"examples":["36","40"]}],"sample":[{"name":"Ada","age":"36"},{"name":"Grace","age":"40"}]}}

This was useful as a one-call csv inspect result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
