Product price comparison API
Find the cheapest delivered price—not the smallest sticker price.
TaskRail's cheapest delivered price API matches an exact product and variant, checks supported sources, and compares the known total after shipping and mandatory fees. Unknown tax is reported as unknown, never silently treated as zero.

The live sample uses one fixed product and postal code. A small global daily cap bounds source cost; fresh cached results remain free.
What the API returns
- Matched product identity and variant confidence.
- Known delivered total, stock status, merchant, and source URL.
- Sources checked, failed sources, freshness, limitations, and evidence.
Use it from an agent or backend
Call POST /v1/deals/new/standard, or connect to the remote MCP endpoint. Production requests cost $0.05 USDC through x402 and need no TaskRail account or API key. See the OpenAPI contract and copy-ready examples.
