What it does

Audit a CSV or JSON-array dataset (up to 50,000 rows, 200 columns, 5 MB) and return a structured data-quality report as JSON: exact duplicate row count and up to 20 duplicate row indexes, per-column missing-value counts and percentages, inferred column types with a mixed-type flag, class-imbalance ratio for low-cardinality categorical columns, IQR-based outlier counts for numeric columns, PII-pattern hit counts (email/phone-like/SSN-like/credit-card-like) per column, and one overall quality_score (0-100, documented heuristic). Row content is never echoed back — only counts, percentages and indexes. Your data is held only in a temporary file for the duration of the request, deleted immediately after, and never logged or retained. PII-pattern hits (email/phone/SSN/credit-card-like) lower the quality_score but the matched values themselves are never returned. Do not submit data you are not authorized to process; this is a diagnostic tool, not a compliance or legal service. This is a triage heuristic for ML/data pipelines, not a certified data-quality or compliance audit.

Use with an agent

Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
Inspect. Fetch /resources/15985.json for the price and payment options.
Pay. Call GET https://qf-api.quietforge-studio.workers.dev/v1/dataset-audit. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
