How Marketlens differs from pmdata.dev
pmdata.dev is the closest philosophical neighbour: tick by tick book updates and a full archive on every plan. The difference is scope and tooling. pmdata.dev covers crypto up/down markets; Marketlens covers every recurring Polymarket market type, including sports, weather, equities earnings, and structured products, with the same change level capture.
On tooling, pmdata.dev hands you Parquet files for hftbacktest. Marketlens serves both workflows: a query API and SDK for interactive research, bulk Parquet exports for offline pipelines, and its own backtesting engine with queue priority, latency, and fee modelling, so you do not need to assemble a separate harness unless you want to.
Which should you pick?
Pick marketlens
Every recurring Polymarket market type at millisecond book resolution, a permanent archive on every tier including free, backtesting with queue priority and fees, Parquet exports, and an MCP server. Pro is $29/mo.
Pick pmdata.dev
Your pipeline is already built on hftbacktest and crypto up/down markets are your entire universe. pmdata.dev's exports are shaped for exactly that stack, with archive coverage since February 2026.
