Introduction

What can I do with the multiexplorer API?

The Multiexplorer API can be used to create a cryptocurrency wallet that is both lightweight (meaning it doesn not use large amounts of bandwidth, memory and hard drive space) and decentralized.

Doesn't building a wallet that depends on an expernal service make it centralized?

Only if that wallet was dependent on that one service. If that wallet cross-checked all API calls through other APIs, then decentralization is maintained.

Can I run my own multiexplorer API?

Yes, all the software that runs the multiexplorer API is open source and available on Github.

Who decides which services get used here?

The operators of multiexplorer.com decide which services get used here. If you run your own instance of multiexplorer, you can disable certain services and define your own set.

Block Information

URL general form:

Recommended Transaction Fee

URL general form:
https://multiexplorer.com/api/optimal_fee/[service_id]?currency=[curency_code]
  • service_id is a number corresponding to the number in the table above, or a service mode such as "fallback", "paranoid3". Note, only "average mode" applies for the optimal fee endpoint. Each service returns a different value, so it makes sense to use the value of each service averaged together. Paranoid mode will always fail, because rarely do each service return the exact same recommended fee.
  • The currency argument is required. Must be 3 or 4 letter code.
  • The include_raw argument is also optional. Setting it to true will include the response as it was returned directly from the service.
  • Returned is the amount of satoshi's that should be added as a transaction fee per KiB (1024 bytes).
  • For all currencies except Bitcoin, a fee of $0.02 USD is returned.
