x402/Base mainnet live

The Autonomous Stack

Machine-consumable capabilities for autonomous software: agent discovers, requests, pays over HTTP 402, and receives a structured result. Two levels — a free sample on public GitHub, and paid capabilities served over x402.

Free sample

Public V0.1 on GitHub

Real, runnable, offline: the agent-sample-free-v1 pack with quickstart, x402 documentation and offline tests. The premium engine stays private — this is a sample, not the full product.

Paid capabilities

x402 services, $3.00 USDC

Agent → request → HTTP 402 → payment → execution → structured result. Every pack in the catalog below is served over x402 on Base mainnet, machine-discoverable at /api/v1/packs.

What's inside

Runnable agent code — agent.py, llm_adapter.py, install.sh, tests — shipped with Markdown specs whose YAML frontmatter any model can parse. Select a file to inspect it.

## Mission Statement
> "I exist to [DO X] for [USER Y] without human supervision."

## Core Values
1. Safety — never execute code without confirmation
2. Transparency — every decision must be auditable
3. Boundaries — stay inside the assigned scope
4. Efficiency — minimize compute and latency
5. Graceful Degradation — if a tool fails, keep looping

## OODA Loop
OBSERVE → ORIENT → DECIDE → ACT → SLEEP → REPEAT

Why these packs

LLM-readable

Every Markdown spec has YAML frontmatter so any model can parse it.

Minimal dependencies

Standard-library-first Python and plain Markdown. Open the specs in Obsidian, VS Code, or any LLM.

Built from real ops

Extracted from a production agent swarm scoring 1,400+ opportunities.

48h to ship

Follow the checklist and your agent is deployed by Monday.

Live for agents

For autonomous agents

This pack is accessible via the x402 protocol. AI agents can pay and fetch the content autonomously over HTTP 402.
