How this service works
Fact check workflow — Keyed dataset comparison + Explicit missing-value fill: Keyed dataset comparison + Explicit missing-value fill for supplied fact check workflow records (claims_reviewed, references_collected). 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 independent analytical reports generated by local engines: a keyed dataset comparison report showing row-by-row differences between the primary and secondary datasets (matched on row_id), and an explicit missing-value fill report detailing how null claims_reviewed or references_collected values were handled. Reports cover up to 200 rows and include per-row and per-channel-group breakdowns.
Example use cases
Newsroom claim verification audit
“I have two exports of our newsroom's fact-check tracking sheet from different editors — both have row_id, channel_group, date, claims_reviewed, and references_collected columns. Can you do a keyed comparison between them, fill any missing claims_reviewed values, and produce the two analytical reports so I can see where they diverge?”
Weekly fact-check gap detection
“Here are this week's fact-check workflow records with some null entries in the references_collected field — compare them against last week's records using row_id as the key, fill in the missing values, and give me both reports so I can identify coverage gaps by channel group.”
Multi-channel fact-check performance review
“I've got two datasets of fact-check activity across channel groups A and B for October 2026 — can you run a keyed dataset comparison on claims_reviewed, fill any blanks, and return both analytical reports so I can see which groups are under-referencing their claims?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-news-18-190?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need offline, deterministic keyed comparison between two structured fact-check workflow datasets without any live external lookups or model inference. It is ideal for data-quality workflows in journalism or media organizations that need to reconcile two versions of fact-check tracking records and explicitly handle nulls. At $0.01 USDC for two reports covering up to 200 rows, it is cost-efficient for batch reconciliation tasks. Prefer alternatives if you need real-time claim verification, web search, or AI-based fact assessment.
Side effects
- More than 200 rows submitted — payload rejected with validation error
- Missing required fields (row_id, channel_group, date, claims_reviewed, references_collected) in any row — schema validation failure
- Invalid date format (must be YYYY-MM-DD) — pattern validation error
- No matching keys between primary and secondary datasets — comparison report shows zero matched rows
- Payment not included or invalid x402 payment header — 402 Payment Required response
