Boosty API

A minimal, async-ready client for getting post data from a remote blogging API that requires either a bearer token or a refresh token + device ID combo for authentication. This crate is designed with resiliency in mind: it transparently handles token expiration and retries requests when needed.

Project Status

🚧 This library is under active development.
Breaking changes, refactoring, and architectural updates may occur frequently.
Use with caution in production environments and pin specific versions if needed.

Features

🔐 Authentication

• Static bearer token or refresh-token + device ID (OAuth2-like).
• Automatic token refresh and retry on expiration.
• Clean separation of AuthProvider logic.

🔁 Retry Behavior

The client automatically retries HTTP requests that fail due to transient network errors or expired access tokens.

• Retry logic is centralized in the get_request() method.
• On token expiration, the client performs a refresh (if refresh-token and device ID are set) and retries the request.
• Other error types (like 4xx or business-logic errors) are not retried.

📝 Post API

• Get single post: get_post(blog, id).
• Get multiple posts: get_posts(blog, limit, page_size, start_offset).
• Strongly typed Post struct with serde support.
• Handles "not available" status gracefully.

💬 Comments API

• Get single comments response: get_comments_response(blog_name, post_id, limit, reply_limit, order, offset).
• Get multiple comments: get_all_comments(blog_name, post_id, limit, reply_limit, order).
• Strongly typed Comment and CommentResponse structs with serde support.
• Handles "not available" status gracefully.

🎯 Blog Targets

• Get targets via get_blog_targets(blog_name).
• Create target via create_blog_target(blog_name, description, target_sum, target_type).
• Update target via update_blog_target(target_id, description, target_sum).
• Delete target via delete_blog_target(target_id).

📜 Subscriptions

• Get subscription levels via get_subscription_levels(blog_name, show_free_level).
• Get current user subscriptions via get_user_subscriptions(limit, with_follow), returning a paginated SubscriptionsResponse.

📷 Showcase

• Get showcase data via get_showcase(blog_name, limit, only_visible, offset).
• Change showcase status via change_showcase_status(blog_name, status).

⚙️ Low-level Features

• Async-ready ApiClient using reqwest.
• Custom headers with real-world User-Agent, DNT, Cache-Control, etc.
• Unified error types: ApiError, AuthError with detailed variants.

Installation

Add this to your Cargo.toml:

[dependencies]
boosty_api = "0.24.0"

or

cargo add boosty_api

Example getting single post

use boosty_api::api_client::ApiClient;
use reqwest::Client;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();
    let base_url = "https://api.example.com";

    let api_client = ApiClient::new(client, base_url);

    // Use static bearer token (optional)
    api_client.set_bearer_token("your-access-token").await?;

    // Or use refresh token + device ID
    // api.set_refresh_token_and_device_id("your-refresh-token", "your-device-id").await?;

    let post = api_client.get_post("some-blog-name", "post-id").await?;
    println!("{:#?}", post);

    Ok(())
}

Example getting multiple posts

use boosty_api::api_client::ApiClient;
use reqwest::Client;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new();
    let base_url = "https://api.example.com";

    let api_client = ApiClient::new(client, base_url);

    // Use static bearer token (optional)
    api_client.set_bearer_token("your-access-token").await?;

    // Or use refresh token + device ID
    // api.set_refresh_token_and_device_id("your-refresh-token", "your-device-id").await?;
    let limit = 50;
    let page_size = 10;
    let posts = api_client.get_posts("blog_name", limit, page_size, None).await?;
    println!("{:#?}", posts);

    Ok(())
}

Offset can be used to skip already downloaded posts or to start from a specific post. It consists of fields Post: "sortOrder": 1762949608 + "int_id": 9555337 or PostsResponse: extra: {"offset": "1762949608:9555337"}.

Extracting content from a post or comment

use boosty_api::{model::Post, media_content::ContentItem, traits::HasContent};

fn print_content(post: &Post) {
    let content_items = post.extract_content();
    for item in content_items {
        match item {
            ContentItem::Image { url, id } => {
                println!("Image URL: {url}, ID: {id}");
            }
            ContentItem::Video { url } => {
                println!("Video URL: {url}");
            }
            ContentItem::OkVideo { url, title, vid } => {
                println!("OK Video URL: {url}, Title: {title}, ID: {vid}");
            }
            ContentItem::Audio {
                url,
                title,
                file_type,
                size,
            } => {
                println!(
                    "Audio URL: {url}, Title: {title}, Type: {}, Size: {size}",
                    file_type.as_deref().unwrap_or("unknown")
                );
            }
            ContentItem::Text {
                modificator,
                content,
            } => {
                println!("Text: {content}, Modificator: {modificator}");
            }
            ContentItem::Smile {
                small_url,
                medium_url,
                large_url,
                name,
                is_animated,
            } => {
                println!(
                    "Smile: {name}, Small URL: {small_url}, Medium URL: {medium_url}, Large URL: {large_url}, Animated: {is_animated}"
                );
            }
            ContentItem::Link {
                explicit,
                content,
                url,
            } => {
                println!("Link: {url}, Content: {content}, Explicit: {explicit}");
            }
            ContentItem::File { url, title, size } => {
                println!("File: {title}, URL: {url}, Size: {size}");
            }
            ContentItem::List { style, items } => {
                println!("List style: {style}");
                for (i, group) in items.iter().enumerate() {
                    println!("  Group {i}:");
                    for (j, item) in group.iter().enumerate() {
                        println!("    Item {j}: {item:?}");
                    }
                }
            }
            ContentItem::Unknown => {
                println!("Unknown content type");
            }
        }
    }
}

Authentication

To get access token or refresh token and device_id, you need to log in to the service, then press F12 in the browser and go to the application tab, where you can select local storage. The required keys are _clentId and auth.

There are two options:

1. Static Bearer Token

api_client.set_bearer_token("access-token").await?;

2. Refresh Token Flow

api_client.set_refresh_token_and_device_id("refresh-token", "device-id").await?;

If a post is unavailable and refresh credentials are present, the client will automatically attempt a refresh.

Crate Structure

• api_client — Main entry point. Handles API requests (e.g. fetching posts), manages HTTP headers, and authentication flow.
• auth_provider — Internal module responsible for refresh-token and access-token lifecycle management.
• model — Typed deserialization models for all Boosty API entities (e.g. posts, comments, users, media).
• error — Unified error types covering API, network, and authorization layers.
• media_content — Defines ContentItem and provides utilities for extracting structured media content from API responses.
• traits — Common traits (HasContent, HasTitle, IsAvailable) shared across multiple Boosty entities.

Error Handling

All API and auth operations return Result<T, ApiError> or Result<T, AuthError>, depending on context. Errors are strongly typed and cover:

• HTTP request failures
• JSON (de)serialization issues
• Invalid or expired credentials
• Unsuccessful API status codes
