# Introduction

> NexaLayer is a session-based Network Execution Layer for AI agents and browser automation.

# What is NexaLayer?

NexaLayer is a Network Execution Layer for AI agents, Playwright, Puppeteer, Browser-use, crawlers, and automation scripts. Instead of exposing raw proxy IPs, it wraps dynamic and static network resources into manageable `Session` objects.

A traditional proxy service answers “where does this request come from?” A fingerprint browser answers “who does this browser look like?” NexaLayer focuses on “how does this automation session stay usable, observable, recoverable, and auditable?”

## Core capabilities

* Agent account registration and `X-API-Key` authentication
* Dynamic and static network session lifecycle management
* `proxy.full_url` output for automation tools
* Execution telemetry: `success`, `http_error`, `captcha`, `timeout`, `block`, and `rate_limit`
* Session health score, risk level, and rotation recommendation
* Balance, recharge order, and transaction endpoints
* Controlled natural-language agent routes for safe network-resource operations

Most Agent API calls use:

X-API-Key: ak_your_key
```

## Current product boundary

These docs describe the currently validated Phase 0 surface: registration, API key auth, product listing, balance reads, and transaction reads. Real paid session creation is a controlled path. Before provisioning resources, make sure the account reports `backend_ready=true`.

Browser OS, full workflow orchestration, MCP, and broad fingerprint dimensions are roadmap areas. They are not documented here as generally available public features.
