Window alignment

All market windows are aligned to UTC boundaries. For example, 5min windows start at :00, :05, :10, … relative to the hour, and daily windows start at 00:00:00 UTC. When you pass a timestamp to a target endpoint, the API aligns it to the correct window boundary automatically.

Polymarket crypto up/down TWAP change

Starting August 7, 2026 at 00:00 UTC, Polymarket crypto up/down markets move from a single snapshot close to a Chainlink TWAP closing reference:

Market type	Opening target / price-to-beat	Closing reference
`5min`	Same target price endpoint as before	30s Chainlink TWAP at market end
`15min`	Same target price endpoint as before	60s Chainlink TWAP at market end
`4hour`	Same target price endpoint as before	60s Chainlink TWAP at market end

The target price does not change. Use /api/v1/targets/* for the market opening target / price-to-beat, and /api/v1/twap/* for the TWAP closing reference. Example BTC 5m market:

slug:  btc-updown-5m-1785603000
start: 1785603000
end:   1785603300
utc:   2026-08-01 16:50:00 -> 16:55:00

Target / price-to-beat:

curl "https://api.vatic.trading/api/v1/targets/timestamp?asset=btc&type=5min&timestamp=1785603000"

Snapshot close / old spot close:

curl "https://api.vatic.trading/api/v1/targets/timestamp?asset=btc&type=5min&timestamp=1785603300"

curl "https://api.vatic.trading/api/v1/twap/report?asset=btc&window=30&timestamp=1785603300"
