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

x402-cloudflare-starter AGENTS.md 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 4d 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.

What it actually says

AGENTS.md

This repository is the ANAMIZED x402 agent checkout for Cloudflare Workers.

What this project does

It lets agents pay USDC on Base Mainnet and Solana Mainnet using x402 for the same first-dollar SKUs sold on Stripe:

  • Agentic OS Cycle $0.75GET /v1/cycle
  • OpenGOS Advanced Search $0.40GET /v1/search
  • OpenGOS Proposal Draft $2.50GET /v1/draft
  • Agentic Trading Decision Cycle $4.00GET /v1/trading

Humans keep using live Stripe Payment Links. Do not invent URLs.

Payments are verified via the PayAI facilitator. A 200 on a paid route is a receipt, not a Desk entitlement write. Trading receipts are not live execution.

Key files

Path Purpose
src/catalog.ts Canonical SKU table (prices + Stripe parallels)
src/index.ts Cloudflare Worker (Hono + x402 middleware)
scripts/test-client.ts Auto-paying test client
wrangler.toml Cloudflare Workers configuration
mcp/server.ts MCP server for agent discovery & tooling

Conventions

  • Runtime: Cloudflare Workers + Hono
  • Payments: x402 protocol (exact scheme)
  • Networks: Base (eip155:8453) + Solana (solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp)
  • Facilitator: PayAI (@payai/facilitator) — no API key required on free tier
  • Secrets via wrangler secret put (never commit private keys)
  • Fail-closed: misconfigured payTo → 500 + Stripe fallback link

Boundaries

  • Do not invent Stripe links or prices
  • Do not claim a paid x402 call unlocks Studio / seats
  • Do not claim /v1/trading executes live trades
  • Do not switch the default facilitator to CDP unless the user explicitly wants Coinbase
  • Prefer keeping the codebase minimal and readable

Useful commands

npm run dev
npm run deploy
npx wrangler secret put BASE_ADDRESS
npx wrangler secret put SOLANA_ADDRESS
Changes

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.
