− # RobotBase — The Semantic Risk & Verification MCP for Web3 Agents− > RobotBase is the **semantic risk and verification layer for Web3 agents**: one read-only Model− > Context Protocol (MCP) endpoint where an autonomous agent answers the two questions that block it− > from acting — *did this payment actually settle*, and *what will the next one cost*. All answers− > come from mainnet nodes we run on our own bare metal. We publish no RPC endpoint of any kind:− > every read path is the MCP surface. No API key, no account, no tracking.− > Chain states (2026-10-14). States are maturity labels, not a ranking — there is no Tier 1/2/3:− > - **Live** — Bitcoin, Ethereum, Monero, Zcash: self-hosted mainnet nodes answering queries now.− > - **Provisioning** — Solana, Base, Tron: being wired into the aggregation layer. Solana and Base− > are served through light API aggregation refined by us, deliberately **not** as heavy local− > nodes. Not answering queries yet; do not treat these as available.− > Scope note (2026-10-14): the roster is **fixed at seven chains**. Litecoin, Dogecoin, Kaspa and− > from this file, from `/api/nodes` and from every MCP tool**. Do not infer an eighth chain from it− > and do not treat it as available — this file remains the authoritative seven-chain roster.− - MCP (Streamable HTTP, protocol 2025-06-18): https://robotbase.cc/mcp− - Pricing, purchase and API-key top-up: https://robotbase.cc/billing/pricing− - API-key usage (plain JSON): https://robotbase.cc/billing/v1/usage?key=rb_…− - Merchant reconciliation middleware: read-only API keys, on-chain proof settlement, zero− private-key custody.− - **Verification tools (13) are free, permanently**: no key, no signup, no metering. Anonymous limit− of 120 requests/minute per IP.− - **Risk intelligence (4 tools) is metered**: 5 calls per day per IP, resetting at 00:00− Asia/Shanghai. Past that the tool answers `Payment Required` and names the top-up page instead of− returning a partial result. Every risk-tool answer carries its own `_metering` block with the− allowance, the reset time and the remaining calls, so a caller is never charged by surprise.− - **API key = the paid tier, paid in USDT (TRC-20) or BTC on-chain** at− https://robotbase.cc/billing/pricing. Keys are issued automatically: a payment watcher sweeps both− networks, matches the transfer against the invoice, and the invoice page shows the key the moment− the transfer confirms — no human, no support ticket. The key lifts the daily risk-tool cap entirely and raises the− rate limit from 120 to 600 requests/minute; send it as `X-API-Key` on the same endpoint. This is− the primary billing model because it is what Cursor, Claude Desktop and every other mainstream MCP− client can actually use today.− - **Pioneer beta**: the first 100 developers get an API key free, which is why a key can be issued− before unit pricing is published. Developers who never exceed 5 risk calls a day never need one.− - **X402 is an experimental lab track, not the billing system.** Machine-to-machine HTTP 402− settlement is on the roadmap, but mainstream MCP clients cannot answer a 402 challenge yet, so it− is documented as a future capability rather than a paid path you can use now.− - With API key: 600 requests/minute per IP− ## MCP tools (17, all read-only)− - xmr_get_node_status — mainnet node height, tx pool, database size and difficulty.+ # RobotBase — Search.
