• Name of the dApp/Project that you are building
Prefer not say. It not a good image of having a broken app due to Data price feed.

• Contact (Telegram/Email/Discord)
@unicornDegen

The more context you provide, the faster we can help.

So we meet the team in Lisabon. We have an app that scalling. The gap in the price feed keeps returning 0 as price. So as a trading app if the data comes back as 0, that means is an error and incorrect.
In the app user places bets, betting on the price of what will be solana , app track the price and when it come time to settle we get 0 , and it comes that the user has lost. but they haven’t.

gm thank you for your question!

Will try to get back to you as soon as possible

And also we’ll try to backfill the data gaps if possible. Would you be okay if I provide you with a csv of the missing data?

3

the history is not the problem. I have 200 User daily waiting to onboard and I can’t if I have don’t certainty that there wont be gaps, or gaps will be filled with 5min timeframe of appearing.

the list of data I gaps I gave an example from above.

4

do you mind reaching out to @mariopyth on telegram?

would like to learn more about your usecase.

Hi @chrisbuildthis,

These gaps happen when the validators don’t reach consensus on that specified time (due to one validator being down/having issues) and while they are rare they are plausible. Please note that in these cases, for instance if a price is missing at time 1749031662, you can use the first price after 1749031664 in this case as the unique price at that time on-chain using this method and fetching it via Hermes using this endpoint will give you that data.

As a meta comment, this happens due to the Solana consensus designs which Pythnet is based on that a validator becomes the leader for 1.6 seconds and if they are down, no block is produced. We totally understand that this not good andare working on improving the reliability of every single validator and changing this behaviour in the network.

OK so that is a 2min gap.
The question it still not clear if the gap is always there ?

or do i need to search for the next timestamp that return me a data ?

It’s a 2 second gap.

No it is not clear or deterministic. If all validators are healthy there’d be no gap. This happens if there is an issue with a validator (like a network issue/…) which is not predictable.

The API I shared looks forwards to give you the first price update after the asked timestamp. if you subscribe to prices you can enable the verbose flag and you always get prev_publish_time and you can assume that the update is valid between the previous publish time and the current publish time.
