buy_api_key
Buy a 30-day 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.

predict_history
Polymarket odds 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.

predict_markets
Polymarket odds board
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.

pregrad_signals
Pre-graduation Solana 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.

radar_alerts
Trend 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.

scan_token
Token safety scan (free)
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).

swap_evm_price
EVM swap price preview
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.

swap_evm_quote
EVM swap quote (ready to sign)
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.

token_launches
Fresh token launches (pre-read)
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.

token_report
Full token due-diligence 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.

token_risk_deep
Deep token risk report
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.

token_risk_verdict
Token risk verdict (A+ to F)
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.

wallet_exposure
Wallet risk exposure read
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.

x402_provider_risk
x402 seller risk grade
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.
