atproto-client

AT Protocol HTTP client with authentication support.

Overview

HTTP client for AT Protocol services supporting DPoP, bearer tokens, and sessions with native XRPC protocol operations and repository management.

Features

• Multiple authentication methods: DPoP, Bearer tokens, and session-based authentication
• XRPC protocol support: Native support for AT Protocol's XRPC communication protocol
• Repository operations: Complete client for AT Protocol repository CRUD operations
• Session management: Authentication session creation, refresh, and validation
• URL utilities: Helper functions for AT Protocol URL construction and validation

CLI Tools

The following command-line tools are available when built with the clap feature:

• atproto-client-auth: Create and refresh authentication sessions using identifier and password
• atproto-client-app-password: Make authenticated XRPC calls using app password Bearer tokens
• atproto-client-dpop: Make authenticated XRPC calls using DPoP (Demonstration of Proof-of-Possession) tokens

Usage

Basic HTTP Operations

use atproto_client::client;
use reqwest::Client;

let http_client = Client::new();
let response = client::get_json(&http_client, "https://api.example.com/data").await?;

DPoP Authentication

use atproto_client::client::{DPoPAuth, get_dpop_json};
use atproto_identity::key::identify_key;

let dpop_auth = DPoPAuth {
    dpop_private_key_data: identify_key("did:key:zQ3sh...")?,
    oauth_access_token: "your_access_token".to_string(),
};

let response = get_dpop_json(&http_client, &dpop_auth, "https://pds.example.com/xrpc/...").await?;

Repository Operations

use atproto_client::com::atproto::repo::{create_record, CreateRecordRequest};

let create_request = CreateRecordRequest {
    repo: "did:plc:user123".to_string(),
    collection: "app.bsky.feed.post".to_string(),
    record: json!({"$type": "app.bsky.feed.post", "text": "Hello!"}),
    // ...
};

let response = create_record(&http_client, &dpop_auth, pds_url, create_request).await?;
