# Agentra™ -- Trust Infrastructure for Autonomous AI Agents
# Patent Pending

> Agentra is the identity oracle and trust layer for autonomous AI agent transactions. It provides bidirectional trust verification, scoring both the sending agent and the receiving counterparty on every transaction. Non-custodial: Agentra authorizes transactions but never touches private keys or custodies funds.

## API

Base URL: https://api.agentrapay.ai
Network: Base Mainnet (Chain ID 8453)
Settlement: USDC on Base

## Core Endpoints

- POST /agents/{id}/kya -- Submit Know Your Agent identity verification
- POST /v1/authorizations -- Create a trust-verified payment authorization with EAS attestation
- POST /v1/authorizations/{id}/settle -- Record settlement of a completed authorization
- GET /v1/trust/{agent_id} -- Query an agent's trust score and tier (Unverified/Basic/Standard/Enhanced)
- POST /v1/wallets/provision -- Provision a non-custodial smart wallet via Turnkey WaaS
- POST /v1/keys -- Generate a service API key
- GET /v1/health -- Service health and network status

## MCP Server

- POST /mcp -- JSON-RPC 2.0 MCP endpoint (6 tools, 3 resources)

## Authentication

API keys via X-API-Key header. Agent keys use agn_ prefix. Service keys use ask_ prefix.

## Trust Model

Bidirectional: every transaction verifies both the sending agent and the receiving counterparty. Trust tiers (Unverified, Basic, Standard, Enhanced) gate transaction limits and capabilities. On-chain attestations via Ethereum Attestation Service (EAS) on Base.

## On-Chain

- AgentTrustAttestation: 0x6089A2023AF60a59ebbAF94212ecf557398A90F7
- EAS Schema UID: 0xe1fae0da770807fc242cfda60d7739a976f10d84cde3371a00f715ff28e6ecf7
- USDC (Base Mainnet): 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

## Revenue Model

Per-authorization handshake fees + per-lookup trust score API fees. Free tier: 100 authorizations + 50 trust lookups/month.

## Technical Stack

Rust/Axum, PostgreSQL, Base Mainnet (ERC-4337), Turnkey WaaS, EAS, x402 protocol
