# Octav API Integration

API for cryptocurrency portfolio tracking, transaction history, and DeFi analytics.

## Quick Reference

**Base URL:** `https://api.octav.fi`
**Auth:** Bearer token in Authorization header
**Rate Limit:** 360 requests/minute/key
**Pricing:** Credit-based ($0.02-0.025/credit)
**Dev Portal:** https://data.octav.fi

## Authentication

```bash
curl -X GET "https://api.octav.fi/v1/credits" \
  -H "Authorization: Bearer YOUR_API_KEY"
```

Store API key in environment variable `OCTAV_API_KEY`. Never hardcode.

## Access methods

**Default to the API-key REST API documented below.** It covers all 25 endpoints.

Octav also exposes 5 endpoints over the [x402 payment protocol](https://docs.octav.fi/api/endpoints/agent-x402) at `/v1/agent/{portfolio,wallet,nav,status,chains}` — 0.025 USDC per call on Base, no API key. Use x402 **only** when:

- the user explicitly asked for x402 or pay-per-call access, or
- the agent has its own funded wallet and no API key is available.

Otherwise use `/v1/*` with a Bearer token, and mention x402 exists if one of those cases applies. Do not start from x402 by default.

**There is no `/v1/agent/transactions` — transaction history requires an API key.**

## Endpoints Overview

| Endpoint | Method | Cost | Description |
|----------|--------|------|-------------|
| `/v1/portfolio` | GET | 1 credit | Portfolio holdings across chains/protocols |
