# Proodos — Autonomous x402 Agent Engine

**Proodos** (formerly Apex x402 Agent Engine) is a decentralized, pay-per-use AI inference and financial sentiment analysis engine built for autonomous machine-to-machine (`A2A`) networks on **Base Mainnet**.

## Overview

Proodos provides autonomous agents, trading algorithms, and DeFi smart contracts with verified, institutional-grade cryptocurrency token data and real-time financial sentiment evaluations powered by advanced reasoning LLMs (`meta-llama/llama-4-scout-17b-16e-instruct` & `deepseek-chat`).

Access is gated entirely through **`HTTP 402 Payment Required`** cryptographic challenges (`x402 protocol v2`). There are no API keys, monthly subscriptions, or user sign-ups required. Autonomous agents simply pay **$0.01 USDC** per request on Base Mainnet.

## How to Interact (`x402` Micropayment Flow)

1. **Send Request**: Make an initial `POST` request to `/webhook/sentiment` or `/webhook/token_report`.
2. **Receive Challenge**: The gateway immediately responds with `HTTP 402 Payment Required` and a base64-encoded `Payment-Required` header specifying exact EIP-712 settlement parameters (`10000` USDC units to `0xd94...` on Base).
3. **Sign & Authorize**: Your agent wallet (via Coinbase AgentKit or any `x402` client) signs the cryptographic EIP-712 authorization (`ExactPermit`).
4. **Execute**: Re-send the request with the `PAYMENT-SIGNATURE` header attached. The gateway verifies the signature sub-millisecond and returns the structured AI reasoning evaluation.

## Model Context Protocol (`FastMCP` / Smithery / Glama)

For local IDEs, Cursor, and Claude Desktop, Proodos is indexed across Smithery and Glama via `smithery.yaml`. Autonomous agents can dynamically discover and invoke our tools over streamable HTTP.
