PriceSettlement is the pair of numbers that decided a price-feed market: the deciding candle's open and close.

Published so a settled window can show what happened — price to beat, final price, the difference, and which way it went — WITHOUT reading the asset price history. That independence is the point: history is recorded best-effort over a websocket, so a gap in it must degrade the chart and not the answer. These numbers came from the exchange candle that actually settled the market.

nil for anything not settled from a candle.

candle_start
string

The deciding candle's opening instant, ISO-8601 UTC. Reproducible: anyone can re-request this exact candle and get these exact numbers.

Example:

"2026-07-22T18:00:00Z"

close
number
Example:

69200.5

granularity_seconds
integer
Example:

300

open
number
Example:

68500.75

symbol
string

Coinbase product id, e.g. "BTC-USD".

Example:

"BTC-USD"

tie
boolean

True when close == open exactly, which at five-minute granularity on a quiet market is a real outcome rather than a rounding artefact. Published because the rule that breaks it (ties resolve up) is otherwise invisible on the one market where it decided the answer.

Example:

false
