noesis-api 0.3.1

//! Official Rust SDK for the [Noesis](https://noesisapi.dev) on-chain
//! intelligence API — Solana token & wallet analytics.
//!
//! All endpoints return [`serde_json::Value`]. Deserialize into your own
//! domain types as needed — the SDK is deliberately schema-agnostic so new
//! response fields don't break compilation.
//!
//! Get an API key at [noesisapi.dev/keys](https://noesisapi.dev/keys).
//!
//! # Example
//!
//! ```no_run
//! use noesis_api::Noesis;
//!
//! # async fn demo() -> Result<(), noesis_api::Error> {
//! let client = Noesis::new("se_...");
//!
//! let preview = client.token_preview("So11111111111111111111111111111111111111112").await?;
//! println!("{preview:#}");
//!
//! let bundles = client.token_bundles("<MINT>").await?;
//! println!("{bundles:#}");
//! # Ok(()) }
//! ```
//!
//! # Rate limits
//!
//! Endpoints are tagged **Light** (1 req/sec), **Heavy** (1 req / 5 sec),
//! or **VeryHeavy** (1 req/min, internal only). The API returns HTTP 429
//! when you exceed the limit; this surfaces as [`Error::RateLimit`] with
//! a typed `retry_after_seconds` field.
