Resource: Arch Tools — 58 API tools with x402 payments for A2A agents

[Deesmo]

Hi! Great work on a2a-x402-typescript.

Building something complementary — Arch Tools is a marketplace of 58 production API tools where every endpoint accepts x402 USDC payments. Agents built with this A2A framework can call real-world tools (web scraping, AI generation, crypto data, OCR) and pay per-call with USDC.

Real 402 response example:

curl -X POST https://arch-ai-tools.onrender.com/v1/tools/web-scrape \
  -d '{"url":"https://techcrunch.com"}'
# Returns: {"x402Version":1,"accepts":[{"network":"eip155:8453","maxAmountRequired":"5000",...}]}

Might be useful for anyone building A2A agents that need to access external APIs. Patent-pending agent auth protocol also filed this month.
