api record

HostDeFi token-safety intelligence and non-custodial EVM swaps. scan_token is FREE (no payment, fair-use capped) — start there. The deeper tools are machine-payable per call over the x402 protocol (USDC on Solana/Base/Polygon/Arbitrum/Avalanche; charge-on-success only). swap_evm_quote returns a ready-to-sign transaction for your own wallet (a 1% native-coin fee is priced in). Paid tools follow one flow: 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…

_ is it live, free and safe measured by this hub
Is hostdefi-x402 live?
Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
Is hostdefi-x402 free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does hostdefi-x402 have?
15 tools: token_risk_verdict, token_risk_deep, buy_api_key, token_report, pregrad_signals, get_x402_pricing, radar_alerts, predict_history, ….
Is hostdefi-x402 safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 19 doors on this origin, so the chain figures are the operator's.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • radar_alerts reads 0.01 USDC paid 1h ago

    PAID ($0.01/call). Recent HostDeFi trend-radar alerts: big dated movers with real market cap, structured JSON.

    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.

  • swap_evm_quote reads 0.01 USDC paid 24h ago

    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.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 2bb60a1fa43ceca1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2bb60a1fa43ceca1/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
