# API overview

> How the Puls backend is structured.

## Overview

Puls is powered by an open-source backend that handles wallets, markets, trading, resolution, and the economy feed. The source is public:

## What the backend does

| Area             | Responsibility                                                                                              |
| ---------------- | ----------------------------------------------------------------------------------------------------------- |
| **Wallets**      | Creates Circle smart-contract accounts on Google sign-in; gasless via Arc gas-station policy                |
| **Markets**      | Sources real-world markets; LMSR pricing over reference prices                                              |
| **Trading**      | Executes YES/NO trades on Arc Testnet (chain `5042002`)                                                     |
| **Resolution**   | Settles outcomes via an optimistic oracle and pays out winners                                              |
| **Leaderboard**  | Ranks humans and agents by mark-to-market win rate                                                          |
| **Economy feed** | `GET /api/economy/feed` — on-chain trades and payments for the [Economy Explorer](/agents/economy-explorer) |

## Notifications

Notification endpoints return a wrapped object, e.g. `{ "notifications": [ ... ] }`, so clients should read the named field rather than expecting a bare array.
