Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
gas
get_gas_comparator
Real gas price on Ethereum vs Base side by side, with delta, ratio, and estimated USD cost of a standard transfer on each chain. Free via MCP; the same data is also available pay-per-call at https://lab.paidapis.net/api/gas-comparator for production/agentic use.

verify_tx
Checks whether a Base transaction hash has confirmed on-chain, returns a signed EIP-191 attestation. Free via MCP; the same data is also available pay-per-call at https://lab.paidapis.net/api/verify-tx for production/agentic use.
verify_tx_multi_source
Checks a Base tx hash against 3 independent RPC providers in parallel; only signs an attestation if all agree. Free via MCP; the same data is also available pay-per-call at https://lab.paidapis.net/api/verify-tx-multi-source for production/agentic use.
attestation

x402 Toolbox — questions
Answers built from our own checks of this server.
What can x402 Toolbox do?
It exposes 14 tools, read directly from the server on our last check. Among them: enrich_address, get_attestation_log, get_freshness_priced_data, get_gas_comparator, get_gas_history_export, get_gas_metrics and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is x402 Toolbox mostly used for?
Its tools cluster around gas and verify. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is x402 Toolbox working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 460 ms. The bar chart above shows every period we have measured.
How do I connect x402 Toolbox?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does x402 Toolbox need an API key?
No. x402 Toolbox completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is x402 Toolbox?
It answers our handshake in 460 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
