    endpoint: "testEndpoint",
    endpoint_params : ["p1","p2"]
})

const thisConstants = []
const thisParts = []
const thisDividers = []
await myZapProvider.initiateProviderCurve({
    endpoint :"testEndpoint",

    dividers : thisDividers
})

const title = await myZapProvider.getTitle()
const pubkey = await myZapProvider.getPubkey()
TODO get next endpoint
