How this service works
Source attribution — String normalisation + Equal-width histogram: String normalisation + Equal-width histogram for supplied source attribution records (cited_sources, verified_links). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.
Output
Returns two analytical reports for the supplied source attribution rows: (1) a string normalisation report cleaning channel_group and related string fields, and (2) an equal-width histogram report for the selected numeric field (cited_sources or verified_links) divided into the specified number of bins, showing bin boundaries and row counts per bin.
Example use cases
News outlet citation volume distribution
“I have 50 daily source attribution records for our news channels — can you normalise the channel_group strings and generate a 10-bin equal-width histogram for the cited_sources field so I can see how citation counts are distributed?”
Verified link coverage analysis
“Run a string normalisation and 5-bin equal-width histogram on the verified_links column for my 120 source attribution rows — I want to understand how evenly verified links are spread across our channel groups.”
Editorial audit of source diversity
“Take these 80 source attribution records and give me a string normalisation pass plus an equal-width histogram with 8 bins on cited_sources, so our editorial team can audit how diverse our sourcing is across dates and channel groups.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-news-02-031?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to both clean/normalise string fields and produce an equal-width histogram of numeric source attribution metrics (cited_sources or verified_links) in a single low-cost call. Ideal for offline batch analysis of news attribution data up to 200 rows where no live lookup or external data enrichment is needed. At $0.01 USDC for two reports, it is cost-effective for routine editorial audits or data quality checks on source attribution datasets.
