API Endpoints

Overview

The ouroborai API is a Hono-based REST server running on Arbitrum One. Routes are organized into groups with different authentication requirements:

Root — public, no authentication
Agent — protected by x402 micropayments
Swap, Automations, Launchpad, v1 Chat — require a readwrite API key
Portfolio, Market, NFTs, Predictions, Bridge — require a readonly API key
Admin — require an admin API key

All API key-protected routes also enforce rate limiting.

Authentication

x402 Payment

Agent routes use the X-PAYMENT header with a signed USDC micropayment. See the x402 payments guide for details.

API Key

Other routes use the Authorization: Bearer <api-key> header. Keys are tiered: readonly, readwrite, and admin. Higher tiers can access lower-tier routes.

Root

Public endpoints for health checks and server metadata.
