Collector code

Our capture runs a rewrite of PMXT's Polymarket orderbook collector. Antonín Kříž wrote the rewrite: 195 of its 196 commits are his and the other is Samuel Tinnerholm's. He licensed his additions 0BSD, so anyone can build on them.

Original collector and historical archive

PMXT (pmxt.dev) wrote the original collector, pmxt-dev/polymarket-orderbook-collector, and published the historical archive at archive.pmxt.dev under CC BY 4.0. Everything under the pmxt/ prefix here is their data, mirrored unmodified.

The AG6 era

AG6 (polymarket-archive.ag6.ai) published a Polymarket orderbook archive, free and without signup. We mirror it under third-party/ag6/, unmodified like the rest. It is the only record this archive has of 2026-08-10T00 to 2026-08-15T09, the hours after PMXT's archive stops. Their own site credits PMXT's collector, so that era is PMXT's code in somebody else's hands.

They publish no licence terms. Checked 2026-08-30: their site publishes no licence text. We credit them anyway. If you plan to redistribute that prefix, the licence question is yours to settle with them.

Thank you to all three. None of them owes anyone this work, and all of them published it anyway.
