Quality Layer
Know Exactly Which Data
to Trust
Validation, scoring, and provenance are built into the pipeline — not bolted on after delivery.
Validation on Every Record
Each data point passes structural and plausibility checks before delivery. Malformed prices, stale pages, and mismatched products are filtered out upstream.
Confidence Scores
Every successful result carries a trust score with per-dimension detail, identity, completeness, price integrity, freshness, so you decide what enters your systems.
Provenance & Audit Trail
Source URL, capture time, crawl metadata, and validation status travel with every record. When a number is questioned, the evidence is attached.
Anomaly Detection
Implausible price moves and offer contamination are flagged automatically, so outliers never silently reach production decisions.

provenance
Production Pipelines
Built to Run While You Sleep
Delivery, history, and reliability semantics designed for systems that run unattended — not for one-off exports.
API & Webhook Delivery
Pull on demand or subscribe to change events. Data arrives where your pipelines already live.
Backfills & Time Series
Request historical price series for analysis, modeling, and seasonality work — not just snapshots.
Defined Freshness SLAs
Every record carries a capture timestamp, so you always know how old the data you're consuming is.
Retry & Validation Semantics
Failed fetches are retried and validated before delivery. You never ingest partial or broken records.
High-Volume Throughput
Millions of price checks per day across your full catalog, without breaking your data pipeline.
No Scraper Maintenance
Marketplace layout changes, anti-bot measures, and source quirks are handled by kwery — not your team.
