vynco

Rust SDK for the VynCo Swiss Corporate Intelligence API. Access 500,000+ Swiss companies from the commercial register with change tracking, sanctions screening, AI-powered risk analysis, network graphs, watchlists, webhooks, and bulk data exports.

Installation

[dependencies]
vynco = "2.0"

For the synchronous (blocking) client:

[dependencies]
vynco = { version = "2.0", features = ["blocking"] }

Quick Start

use vynco::{Client, CompanyListParams};

#[tokio::main]
async fn main() -> Result<(), vynco::VyncoError> {
    let client = Client::builder("vc_live_your_api_key").build()?;

    // List companies with filtering
    let params = CompanyListParams {
        search: Some("Novartis".into()),
        canton: Some("BS".into()),
        ..Default::default()
    };
    let resp = client.companies().list(&params).await?;
    println!("Found {} companies", resp.data.total);

    // Get a single company
    let company = client.companies().get("CHE-105.805.080").await?;
    println!("{}: {:?}", company.data.name, company.data.legal_form);

    // Sanctions screening
    let screening = client.screening().screen(&vynco::ScreeningRequest {
        name: "Suspicious Corp".into(), uid: None, sources: None,
    }).await?;
    println!("Risk: {} ({} hits)", screening.data.risk_level, screening.data.hit_count);

    // AI risk score
    let risk = client.ai().risk_score(&vynco::RiskScoreRequest {
        uid: "CHE-105.805.080".into(),
    }).await?;
    println!("Risk score: {}/100 ({})", risk.data.overall_score, risk.data.risk_level);

    // Credit balance
    let credits = client.credits().balance().await?;
    println!("Credits remaining: {}", credits.data.balance);

    Ok(())
}

Blocking Client

use vynco::blocking::Client;

fn main() -> Result<(), vynco::VyncoError> {
    let client = Client::builder("vc_live_your_api_key")
        .build()?;

    let count = client.companies().count()?;
    println!("Companies: {}", count.data.count);

    Ok(())
}

API Coverage

18 resource modules covering 69 endpoints:

Response Metadata

Every response includes header metadata for credit tracking and rate limiting:

let resp = client.companies().get("CHE-105.805.080").await?;

println!("Request ID: {:?}", resp.meta.request_id);         // X-Request-Id
println!("Credits used: {:?}", resp.meta.credits_used);      // X-Credits-Used
println!("Credits remaining: {:?}", resp.meta.credits_remaining); // X-Credits-Remaining
println!("Rate limit: {:?}", resp.meta.rate_limit_limit);    // X-Rate-Limit-Limit
println!("Rate limit remaining: {:?}", resp.meta.rate_limit_remaining); // X-RateLimit-Remaining
println!("Rate limit reset: {:?}", resp.meta.rate_limit_reset); // X-RateLimit-Reset
println!("Data source: {:?}", resp.meta.data_source);        // X-Data-Source

Example CLI

A full CLI example is included to demonstrate real-world SDK usage:

Configuration

use std::time::Duration;

let client = Client::builder("vc_live_your_api_key")
    .base_url("https://api.vynco.ch")              // default
    .timeout(Duration::from_secs(60))               // default: 30s
    .max_retries(3)                                 // default: 2
    .build()?;

The client automatically retries on HTTP 429 (rate limited) and 5xx (server error) with exponential backoff (500ms x 2^attempt). It respects the Retry-After header when present.

Error Handling

All API errors are mapped to typed variants:

use vynco::VyncoError;

match client.companies().get("CHE-000.000.000").await {
    Ok(resp) => println!("{}", resp.data.name),
    Err(VyncoError::Authentication(_)) => println!("Invalid API key"),
    Err(VyncoError::InsufficientCredits(_)) => println!("Top up credits"),
    Err(VyncoError::Forbidden(_)) => println!("Insufficient permissions"),
    Err(VyncoError::NotFound(body)) => println!("Not found: {:?}", body.detail),
    Err(VyncoError::Validation(body)) => println!("Bad request: {:?}", body.detail),
    Err(VyncoError::Conflict(_)) => println!("Resource conflict"),
    Err(VyncoError::RateLimit(_)) => println!("Rate limited, retry later"),
    Err(VyncoError::Server(_)) => println!("Server error"),
    Err(e) => eprintln!("Error: {e}"),
}

Error bodies follow RFC 7807 Problem Details with error_type, title, status, detail, and instance fields.
