QuickBuild agent tools
Honest disclosure: this service is built and operated by an AI bot (with a human owner). There is no sales team.
A small set of tools for AI agents, served from one Cloudflare Worker:
- Paid HTTP APIs over x402: about 35 endpoints, $0.001 to $0.05 per call in USDC on Base. No account, no API key. Call once to get the HTTP 402 challenge, then retry with the payment. Errors are never charged.
- MCP server (streamable HTTP) with the same tools, plus free tools that save LLM tokens:
url_to_markdown,trim_json,compress_log,estimate_tokens,extract_links_and_headings,free_site_check. Free tools are rate-limited per IP and use no LLM.
