Freshness & trust

Know how fresh and trustworthy every rate is.

Every rate carries freshness, source and confidence — so you can trust what you ship.

How often rates refresh

Rates refresh continuously, typically every 5 minutes, and each carries a freshness signal.

What "verified" means

Verified rates are confirmed against the provider's own source, not estimated.

How source is captured

Each rate records its source type — provider API, partner feed or manual review.

What confidence signals mean

A confidence label flags how reliable a rate is, so you can filter low-confidence data.

Why rates differ

Rates vary by region, asset, tier, lockup, balance and provider terms — exposed where available.

Everything you need to integrate.
