p402-agent-setup

p402-agent-setup is a skill for Claude Code, Codex from Z333Q/p402-protocol. It costs 228 tokens per session (2,895 once invoked), scanned A, original, MIT.

A setup guide for P402, a service that routes AI requests to models and handles usage payments. It works with tools that accept an OpenAI-compatible API.

In plain words
What is it for?
Use it to configure agents built with OpenClaw, CrewAI, AutoGPT, LangChain, or custom Python and TypeScript code.
Why use it?
It explains how to connect an existing agent by changing its API address and key, while covering budgets, caching, and payment settlement.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

p402-agent-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

P402 Agent Setup Skill

Help developers integrate P402 as the AI routing and payment infrastructure for autonomous agents. The goal is the cleanest possible path from "I have an agent running somewhere" to "my agent routes all inference through P402 with budget caps, semantic caching, and on-chain settlement on Base or Tempo."

Core Context

P402 is an OpenAI-compatible API. Any agent framework or tool that can call an OpenAI-style endpoint can use P402 as a drop-in provider. This is the key architectural insight: P402 is not a plugin or SDK dependency. It is a base URL swap.

P402 settles on multiple rails:

  • Base mainnet (chain 8453) for USDC and EURC via EIP-3009 gasless transfers
  • Tempo mainnet (chain 4217) for USDC.e, USDT0, cUSD, and seven other TIP-20 stablecoins, with gas paid in stablecoin

Auto-routing picks the cheaper rail by default (Tempo, when both are healthy). Users can override per request.

The three integration depths, from simplest to richest:

  1. Provider swap (5 minutes): Change baseURL to https://p402.io/api/v2 and set the API key. The agent gets 300+ model routing, semantic caching, and Billing Guard protection with zero code changes.

  2. MCP server (10 minutes): Install @p402/mcp-server globally or locally. The agent gains 6 tools for active session management, provider comparison, and health monitoring. The agent can self-manage its own budget.

  3. SDK or @p402/mpp-method integration (30 minutes): Import @p402/sdk for high-level operations, or @p402/mpp-method for direct mppx-protocol integration when building custom server infrastructure.

Most agent users want option 1 or 2. Reach for option 3 only when building a custom agent framework, integrating mppx directly, or needing programmatic control over sessions and mandates.

Decision Tree

When a user describes their setup, identify two things:

  1. What agent framework? This determines provider configuration.
  2. What hosting environment? This determines secrets management.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
