Try it
Use web_search to find today's Bitcoin fee market news, fetch the top result,
and then call btc_get_fee_rates. Summarize what changed.
Other useful first calls: tron_verify_usdt_transfer (did a USDT payment land?), zec_get_pool_status (shielded-pool supply), cyberlibrary_fulltext_search (search 80k+ public-domain books).
What is free
- 44 verification tools: free forever, no key.
- Web: 100 shared web calls per IP per day.
- Risk + CyberLibrary: 5 calls per day shared; past that, USDC credits via x402.
Troubleshooting
- 402 Payment Required: the free bucket for that tool is used; wait for the daily reset or pay a credit pack.
- Tool not listed: refresh the MCP connection; the hosted surface currently has 72 tools.
- Slow fetch: some sites are unreachable from our egress; the tool returns a readable error or uses the provider fallback.
