# snapdata

> Free, open, daily snapshots of gold, silver, foreign exchange, crude oil and
> equity indices. One unauthenticated GET returns JSON, CSV or plain text. No
> API key, no rate limit, no account.

This is NOT a real-time feed. Values are daily snapshots, frozen at permanent
URLs. A dated snapshot older than 48 hours never changes again, which is what
makes a backtest over it reproducible. If you need tick data, this is the wrong
source.

## Reading a value

Every observation carries its own provenance. Check these before using a number:

- `status`: final | provisional | estimated | missing | not_backfilled
- `is_trading_day`: false means the market was shut. `value` will be null.
- `filled_from`: non-null means the value was carried forward from that date.
- `source`: which upstream it came from.

A closed market yields an explicit null row, never a repeated previous value.
Do not fill gaps by carrying values forward unless you set `filled_from`
yourself and say so.
