Hostdefi X402 missed 3 checks this week
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
token
token_launches
PAID ($0.02/call). Fresh token launches with HostDeFi safety pre-reads baked in: newest token profiles annotated with authority state, bundled-launch flag, holder concentration and market depth — the clean flag is fail-closed (true only when every check is provably good). Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
token_report
PAID ($0.35/call). HostDeFi full due-diligence report — one document: the A+–F verdict, on-chain signals (authority state, bundled-launch read, holder concentration, Token-2022 traps on Solana), the dated verdict-history series, trend-radar mentions and a rug-ledger cross-check. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
token_risk_deep
PAID ($0.25/call). Deep HostDeFi report in one call: the current A+-F verdict with authority/holder signals, the FULL dated safety history for the token, and a derived trend block (grade movement, liquidity trajectory, worst drawdown, days tracked). All figures are computed from recorded rows — no projections. History depth accrues from 2026-08-16. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
token_risk_verdict
PAID ($0.02/call). HostDeFi A+–F token safety verdict by chain + address: grade, score, verdict prose, liquidity/holders/authority signals. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
predict
predict_history
PAID ($0.02/call). 24h odds history for one tracked Polymarket market: [ts, yesUsd, noUsd] points sampled ~1/min into a normalized series — one call, no auth juggling. An untracked market is an uncharged 404. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
predict_markets
PAID ($0.005/call). Polymarket prediction markets HostDeFi tracks (top ~100 by 24h volume): market ids, questions, latest yes/no odds and sampling stats from HostDeFi's own recorded series. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
swap
swap_evm_price
PAID ($0.002/call). EVM swap price preview: expected and minimum output for a pair/amount before committing to a firm quote — the cheap look-before-you-swap call. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
swap_evm_quote
PAID ($0.01/call). Executable EVM swap: a firm KyberSwap-routed quote plus a ready-to-sign transaction for the taker's OWN wallet — non-custodial, no key, no account. A 1% platform fee in the chain's native coin is priced into the returned transaction, on top of the swap. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
x402
get_x402_pricing
FREE. The HostDeFi machine-payable price catalog: every paid resource, its USD price and settlement rails.
x402_provider_risk
PAID ($0.02/call). Vet an x402 seller BEFORE paying it: A–F grade from observable signals (402-spec fidelity, price sanity, payTo presence, TLS, latency), dated crawl snapshot. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
buy
buy_api_key
PAID ($5, one payment). Mint a 30-day HostDeFi Agent-plan API key (5,000 calls, batch enabled) — the key arrives in the paid response; no account, no signup. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
pregrad
pregrad_signals
PAID ($0.05/call). Pre-graduation on-chain signals for a Solana mint: bundled-launch detection, curve-aware holder concentration, Token-2022 traps, authority state. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
radar
radar_alerts
PAID ($0.01/call). Recent HostDeFi trend-radar alerts: big dated movers with real market cap, structured JSON. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.
scan
scan_token
FREE. HostDeFi token-safety scan — pass any token contract address (Solana mint or EVM address), or an exact token name/ticker: structured risk read with concerning/legitimate on-chain signals (authority state, liquidity, holder concentration, contract flags). No payment, no signup — fair use 100 checks/day per IP (the same free scanner as https://hostdefi.com/scan).
wallet
wallet_exposure
PAID ($0.10/call). Wallet risk-exposure read for a Solana wallet: its largest holdings graded through the full verdict path, exposure counts by risk tier, and a rug-ledger symbol cross-check. Holdings exposure heuristics — NOT AML attribution or sanctions screening. Call once WITHOUT x402_payment to receive the x402 payment requirements (an `accepts` array); pay one of them with any x402 client/wallet, then call again with `x402_payment` set to the base64 X-PAYMENT payload. You are only charged when a result actually comes back.

Hostdefi X402 — questions
Answers built from our own checks of this server.
What can Hostdefi X402 do?
It exposes 15 tools, read directly from the server on our last check. Among them: buy_api_key, get_x402_pricing, predict_history, predict_markets, pregrad_signals, radar_alerts and 9 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 Hostdefi X402 mostly used for?
Its tools cluster around token, swap and predict. 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 Hostdefi X402 working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 397 ms. The bar chart above shows every period we have measured.
How do I connect Hostdefi X402?
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 Hostdefi X402 need an API key?
No. Hostdefi X402 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Hostdefi X402?
It answers our handshake in 397 ms on average, which is faster than 31% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
