# About API

RubyScore API — the data layer & growth analytics for Web3

Build faster without running your own nodes. RubyScore provides a **single API across 50+ EVM chains** and a **business-oriented analytics layer** to understand behavior, activate the right users, and automate growth.

***

#### 1) RubyScore On-Chain Data API

For engineering and product teams.\
Query wallets, tokens, contracts, and events **in a unified schema across networks**. Perfect for backends, dApps, bots, internal tools, and dashboards.

#### 2) RubyScore Behavior & Growth Analytics

For growth, ops, and analysts.\
Segment users by **real on-chain activity**, build dynamic cohorts, track cross-protocol journeys, and measure campaign impact.

> Optionally plug in **MRS**, **PoH ID**, and **Score Level** as ready-to-use traits for targeting, gating, and anti-fraud.

### What you can do with the API

* **Wallet snapshots & timelines:** balances, transfers, unique contract interactions, active days/weeks/months, gas spent, volumes.
* **Contract & token telemetry:** event streams (ERC-20/721/1155), function calls, holders, counterparties.
* **Your own scoring:** build quality/value models on normalized multi-chain data.
* **Cohorts & segmentation:** create audiences by behavior (e.g., “active 7/14 days, ≥5 unique contracts, volume ≥ $500”).
* **Quality filters:** exclude low-signal traffic via your own thresholds or reputation traits (MRS / PoH presence / Levels).
* **Personalized UX:** dynamic allowlists, reward rules, and access tiers directly in your app.

***

### How RubyScore helps

* **No nodes or indexers required:** we handle ingestion, indexing, and normalization; you hit clean, consistent endpoints.
* **Real-time streams:** for automations, reward triggers, and safety rules with minimal latency.
* **50+ EVM chains:** Ethereum, Optimism, Arbitrum, Base, and more — coverage keeps expanding.

### Customization (on request — “any blockchain parameter you need”)

We adapt the API, analytics, and rules to your goals and ecosystem specifics.
