Übersicht

The 5-minute snapshot series over [from, to], plus intervalApy: the annualized share-price return between the first and last snapshot in the range, (last/first)^(year/elapsed) - 1, in percent.

Retention is 7 days: an earlier aus is pulled forward and clamped is set true. resolution downsamples by keeping the last snapshot per bucket (real snapshots, never averages) and never changes intervalApy.

Parameter

Parameter	Location	Typ	Erforderlich	Beschreibung
chainId	path	Ganzzahl	Ja	Chain id the vault lives on.
Adresse	path	Zeichenkette	Ja	Vault (ERC-4626 share token) address.
aus	Abfrage	string (date-time)	Nein	Start instant (ISO-8601). Default the trailing 24h before `to`. Clamped forward to the 7-day retention floor.
zu	Abfrage	string (date-time)	Nein	End instant (ISO-8601). Defaults to now.
resolution	Abfrage	Ganzzahl	Nein	Downsample bucket in minutes (5-1440). Omit for the full 5-minute series.

Antwort

Feld	Typ	Erforderlich	Beschreibung
chainId	Ganzzahl	Ja	Numeric identifier of the chain where the vault is deployed.
vaultAddress	Zeichenkette	Ja	Lowercased vault address.
aus	string (date-time)	Ja	Effective start (after retention clamp).
zu	string (date-time)	Ja	Effective end of the requested interval as an ISO 8601 timestamp.
clamped	boolesch	Ja	True when the requested `from` was pulled forward to the retention floor.
retentionDays	Ganzzahl	Ja	The snapshot retention horizon (7).
resolutionMinutes	number | null	Ja	The downsample bucket in minutes, or null for the full 5-minute series.
intervalApy	number | null	Ja	Annualized share-price return between the first and last snapshot in the FULL range (`(last/first)^(year/elapsed) - 1`, in percent, 4dp). Null when there are fewer than two usable share-price snapshots or the elapsed span is under one snapshot cadence. Unaffected by `resolution`.
snapshots	array<object>	Ja	Vault snapshots in chronological order. Downsampling retains complete snapshots rather than averaging their values.
snapshots[].snapshotAt	string (date-time)	Ja	ISO 8601 timestamp when the snapshot was recorded.
snapshots[].apy5m	number | null	Ja	APY percentage over the five-minute lookback window.
snapshots[].apy10m	number | null	Ja	APY percentage over the ten-minute lookback window.
snapshots[].apy30m	number | null	Ja	APY percentage over the 30-minute lookback window.
snapshots[].apy1h	number | null	Ja	APY percentage over the one-hour lookback window.
snapshots[].apy2h	number | null	Ja	APY percentage over the two-hour lookback window.
snapshots[].apy4h	number | null	Ja	APY percentage over the four-hour lookback window.
snapshots[].apy6h	number | null	Ja	APY percentage over the six-hour lookback window.
snapshots[].assetsPerShare	number | null	Ja	Opaque scaled share price with a constant 100x scale. Use it only as a ratio between snapshots, not as a per-share dollar value.
snapshots[].tvlUsd	integer | null	Ja	Vault TVL in whole US dollars, rounded to the nearest dollar.
snapshots[].availableLiquidityUsd	integer | null	Ja	Withdrawable liquidity in whole US dollars, rounded to the nearest dollar.

HTTP responses

Status	Beschreibung
200	The (optionally downsampled) snapshot series and the interval APY.
400	A malformed `from`/`to`, `from >= to`, a range entirely outside the 7-day retention, a bad `resolution`, or a bad path (`invalid_request`).
429	Rate limit exceeded. `Retry-After` (seconds) tells you when to retry. Reads, feedback, and push writes are keyed per IP; create/update/delete are keyed per wallet+IP; deposit/withdraw/claim calldata is keyed per strategy+IP.
500	Internal server error.
