How this service works
Three x402-paid data APIs on one host. PricePlain: Posted US hospital prices (CMS price-transparency files), cleaned: Twin Cities, MN first. Cash and payer-negotiated rates per CPT/DRG code with canonical insurer names, provenance (source file URL + date) and data-quality flags. Posted prices, not quotes. TableGrab: public URL or file -> typed JSON tables / Markdown. City Table Clean: Socrata/CKAN city CSV cleaner with a per-change log.
Output
Returns a JSON object with: a 'cleaned_csv' string containing the deduplicated and date-standardized CSV data, a 'changes' array listing each row-level modification (row number, column, action taken, before/after values), and a 'report' summary with counts of each type of change applied and total duplicates removed.
Example use cases
Cleaning a city crime report CSV
“Clean this Chicago crime data Socrata CSV for me — https://data.cityofchicago.org/resource/ijzp-q8t2.csv — deduplicate it and standardize all the date columns, and show me exactly what was changed row by row.”
Preparing CKAN dataset for analysis
“I need to use this CKAN dataset for a report — can you clean it at https://data.edmonton.ca/api/3/action/datastore_search?resource_id=xyz, deduplicate, fix any messy dates, and return the cleaned CSV with a change log?”
Auditing data quality of a civic dataset
“Before I import this Socrata CSV into my database, can you run it through the City Table Clean endpoint — https://data.minneapolismn.gov/resource/abcd-1234.csv — up to 10000 rows, and give me the full list of changes so I can audit what was normalized?”
Technical details
Endpoint
POSThttps://priceplain.onrender.com/v1/clean?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically have a Socrata (/resource/xxxx-xxxx.csv, /d/xxxx-xxxx, rows.csv) or CKAN city open data URL and need standardized dates, deduplication, and a detailed per-change audit log — not just a raw download. Prefer this over generic CSV parsers when working with civic/government open data portals and you need provenance of every transformation made.
Side effects
- Non-Socrata/CKAN URL returns an error or unsupported format response
- CSV exceeds 50,000 row limit — request must use max_rows to cap it
- URL returns a 403 or 404 if the dataset is private or has been removed
- Malformed or non-CSV content at the URL causes a parsing failure
- x402 payment not completed results in 402 Payment Required response
