Gmgm! Thanks for submitting this, a couple of minor formatting fixes before we merge this in so it's all matching the standards we're trying to push for:

/verify endpoint seems to use valid instead of isValid and is missing invalidReason field (when invalid)

Standard format:
Success: {isValid: true, payer: "0x..."}
Error: {isValid: false, invalidReason: "...", payer: "0x..."}
OpenFacilitator returns:
{valid: true, payer: "0x..."} (missing invalidReason when invalid)

/settle uses errorMessage instead of errorReason, is missing payer field and transaction field (should be empty string "" when failed)

Standard format:
Success: {success: true, payer: "0x...", transaction: "0x...", network: "..."}
Error: {success: false, errorReason: "...", payer: "0x...", transaction: "", network: "..."}
OpenFacilitator returns:
{success: false, errorMessage: "...", network: "..."} (wrong field name, missing payer and transaction)

Thanks! Looping in @phdargen as well in case I'm getting something wrong

Thanks @Must-be-Ash! All fixed:

/verify - now returns {isValid, invalidReason, payer}

/settle - now returns {success, transaction, payer, network, errorReason} with transaction: "" on failure

Let me know if there's anything else I can improve!
