How this service works
Trading journal observations — Duplicate key report + Explicit missing-value fill: Duplicate key report + Explicit missing-value fill for supplied trading journal observations records (entry_price, exit_price). 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 reports: (1) a duplicate key report identifying which row_id values appear more than once across the submitted rows, and (2) a missing-value fill report showing which entry_price or exit_price cells were null and what values were substituted using the chosen method (zero, mean, or median). Both reports are computed locally on the supplied data with no external lookups.
Example use cases
Duplicate trade entry audit
“I have 150 rows of trade records and I think some got duplicated when we merged two broker exports — can you run a duplicate key check on my trading journal rows and tell me which row IDs appear more than once? Here are the rows with fields row_id, instrument_group, date, entry_price, exit_price.”
Median imputation for missing exit prices
“Several of my trade log entries are missing exit_price values — can you fill them in using median imputation across my dataset? I'll give you up to 80 rows with row_id, instrument_group, date, entry_price, and exit_price (some null).”
Combined data quality pass before backtesting
“Before I run my backtest I want to clean my trading journal: check for any duplicate row IDs and also fill missing entry_price fields with zero for the 60 rows I'm sending you — instrument groups are FX and Equities, dates range from 2024-01-01 to 2024-03-31.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-finance-09-070?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined duplicate-detection and missing-value imputation pass on trading journal data in a single low-cost call ($0.01 USDC for both reports). It is ideal for pre-processing trade logs before backtesting, reconciliation, or analysis when you need offline, deterministic computation on your own data without any external lookups or predictions.
Side effects
- Submitting more than 200 rows returns a validation error
- Missing required fields (row_id, instrument_group, date) cause row-level rejection
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation failure
- Selecting a fill method not in [zero, mean, median] returns an enum error
- Submitting fewer than 1 row returns a minItems validation error
- Price values outside ±1,000,000,000,000 are rejected by schema bounds
