Crypto

Chainlink TWAP series (crypto settlement price)

Min tier: free. The Chainlink observations Polymarket settles crypto up/down markets against, oldest first, cursor-paged.

A 5-minute market settles on the 30-second TWAP; a 15-minute market on the 60-second one. window=0 is the Chainlink spot reference carried alongside, which is what makes divergence between spot and settlement measurable.

Eight symbols publish — btc, eth, sol, xrp, bnb, doge, zec, hype (all /usd) — at about one observation per second each.

Settle on value_e18, not value. value_e18 is the exact E18 fixed-point integer; value is a float and is lossy above 2^53.

Supplying symbol makes the read index-bounded. Omitting it scans every symbol over the range, which is why limit is capped at 5000.
