### `fetch_gtin`

- The name "fetch_gtin" says "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What is this GTIN? Returns the signed record for a GTIN-8/12/13/14: product, brand, maker, category and pack where a source page states them, each with the pages it was read from and the date it was read; seen_in markets and banners; confidence confirmed (two or more independent domains agree) or seen (one). A GTIN with no observation answers status unknown with no fields — never a guess. Pass market (hub market code; UK accepted for GB) to tag the ask with the market: a miss is queued as a lead for that market. Can it be sold there is the hub's gate, not this door's.
```
