How this service works

Track category-level price inflation with configurable daily, weekly, or monthly granularity. Returns period-over-period change and overall change.

Output

Returns a time series of price change data at the requested granularity (daily/weekly/monthly), including period-over-period change and overall change across the date range, along with resolved category metadata.

Example use cases

Example prompt

“Show me monthly price inflation for the electronics category in the US from April 1 to May 1, 2026 — I want to see how much prices have changed period over period.”

When to prefer

Use this endpoint when you need to measure how prices in a specific retail category have changed over time — not just the current price level, but the rate of change (inflation). Ideal for trend analysis, cost monitoring, and economic research on retail categories. Prefer over Price Dispersion (which measures spread, not change) or Brand Tracker (which tracks a specific brand, not category-wide inflation).

Side effects

Invalid date format returns 400 with parsing error
Unknown or unmappable category string returns error or empty result if embedding kNN finds no match
Unsupported country code (not 'us' or 'ca') returns 400 validation error
Date range with no data available returns empty series
Payment failure or insufficient USDC balance returns 402

Input

Schema · Request body

Field	Type	Description
to	string	End date (ISO 8601, defaults to now)
from	string	Start date (ISO 8601, defaults to 30 days ago)
country	string	Country (us or ca)
category	string	Product category (e.g., electronics, grocery, beauty). Fuzzy human-readable input — the resolver maps it through tier 1-4 (id → exact name → trigram → embedding kNN) to a canonical category_id. Pair with `category_id` if you have a deterministic id from a prior call.
department	string	Coarse depth-1 BrowseNodes department label (e.g., 'Electronics', 'Grocery', 'Toys & Games'). Exact-match, case-sensitive Title Case. Optional alongside `category`; either parameter alone or both together are accepted. Use this for stable cross-agent queries where the leaf-level category is too noisy.
category_id	integer	Deterministic category id. When set, bypasses the fuzzy resolver cascade and uses tier 1 (id lookup) directly. Agents that learned a canonical id from a prior call's `resolved.category_id` should pin it here for round-trip stability.
granularity	string	Time granularity for the series
