Proxagora Documentation

Proxagora is an API marketplace built for AI agents. It provides a catalog of data APIs accessible via per-call micropayments — no accounts, no API keys, no monthly subscriptions.

How It Works

Three primitives:

Discover — GET /api/discover returns the full API catalog with IDs, descriptions, categories, and per-call costs in USDC.

Call — POST /api/{id} with your request parameters. Returns data on success, or HTTP 402 with payment instructions if payment is missing.

Pay — Attach payment proof via X-Payment (x402/blockchain) or X-MPP-Payment (Stripe) header. Payment validates on-chain or via Stripe and the API responds with data.

Base URLs

| Environment | URL | |-------------|-----| | Production | https://proxagora.com | | Development | http://localhost:3000 |

Quick Start

# 1. Get the API catalog
curl https://proxagora.com/api/discover

# 2. Call an API (returns 402 without payment)
curl -X POST https://proxagora.com/api/ip-geo \
  -H "Content-Type: application/json" \
  -d '{"ip": "8.8.8.8"}'

# 3. Retry with payment header (x402 or Stripe MPP)
curl -X POST https://proxagora.com/api/ip-geo \
  -H "Content-Type: application/json" \
  -H "X-Payment: <base64-encoded-payment>" \
  -d '{"ip": "8.8.8.8"}'

Payment Methods

| Method | Header | Use Case | |--------|--------|----------| | x402 (USDC on Base) | X-Payment | Autonomous agents, production | | Stripe MPP | X-MPP-Payment | Developer testing, teams |
