I think the issue here is that this job seems to have a 200 KPR bonded requirement… Check the ‘minKeep’ variable in the job contract.

No problem! To be honest it had me questioning also for a while why the contract was failing while it was workable.

@andre.cronje, is it an idea to list these bonding requirements in the job description because now the only way seems to be digging in the contract code/variables. Is the variable universal for the different jobs? So will will it always be named ‘minKeep’ or is this up to the job contract creator?

Good idea, I’ll add an interface for Keep3rV1JobRegistry so that it is included, but it is up to the Job to implement. For example a Job might start at 0 requirement and work up to > value if security requires it. A good idea is to include a standard interface to jobs, something along the lines of overriding isKeeper and hasCredits so that keepers can filter easier.

Great suggestion, thank you

Hi Andre

I appreciate this thread is a few months old, but did a solution to the problem of ascertaining Keeper prerequisites ever get implemented? If not, is the only way of achieving this to look at the source code and/or view the Read Contract information on etherscan?

Nige
