Accessing your PDS

PLC is a persistent global identifier system, stands for “Public Ledger of Credentials”, it’s a persistent global identifier system, which allows accounts to retain relationships while changing names or migrating between service providers

DID resolution can be as simple as:

import gleam/http/request
import possum

let assert Ok(did) = did.parse("did:plc:z72i7hdynmk6r22z27h6tvur")

// Send a request to plc.directory
let request = possum.get_plc_data(did)

// You can use a decoder like this for your PDS endpoint
let decoder =
  decode.at(["services", "atproto_pds", "endpoint"], decode.string)
