HostDeFi

One call in, one verdict out. POST a token address and get back the same proprietaryA+–F Safety Readthat powers HostDeFi's token pages — a graded score with plain-English receipts of what was checked and, honestly, what could not be —plus the pre-graduation on-chain signals most risk APIs are blind to: bundled-launch detection, curve-aware holder concentration, and Token-2022 trap flags. Built for the people who scan tokens thousands of times a day: Solana trading bots, wallets, portfolio apps and DEX front-ends.

Base URLhttps://hostdefi.com/api— so the graded verdict lives at/api/v1/token-risk. (The legacyawake-integrity-production-faa0.up.railway.apphost keeps working for existing integrations, but new code should use the hostdefi.com base — it is the one we guarantee.)

The verdict path never calls an LLM, so responses are fast and deterministic. All figures are computed from public on-chain and market data at request time and stamped withcheckedAt.

Prices are SOL-denominated and may be adjusted as the SOL price moves — checkGET /v1/healthfor the current table.

POST /v1/token-risk— body{ "query": "<address or name/ticker>" }.
GET /v1/token-risk/:chain/:address— when you already know the chain (solana,ethereum,bsc,base,arbitrum,optimism,polygon,avalanche).

# Free tier — no key needed curl -s https://hostdefi.com/api/v1/token-risk \ -H 'Content-Type: application/json' \ -d '{"query":"DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263"}' # Paid tier — send your key curl -s https://hostdefi.com/api/v1/token-risk \ -H 'Content-Type: application/json' -H 'x-api-key: vx_your_key' \ -d '{"query":"WIF"}'

When a token launches on a bonding curve it has no DEX pool yet, so pool-based tools return nothing about it — exactly when a sniper most needs a read. HostDeFi reads the mint directly on-chain and returns, for brand-new tokens:bundled-launch detection(launch.bundled— supply split across wallets that all bought in the same block, which defeats naive concentration checks),curve-aware concentration(holders.top10Pctwith the bonding-curve account excluded, so a healthy token doesn't read 99% held), andToken-2022 trap flags(token2022Extensions— permanent delegate, transfer hook, pausable and the rest).launch.preGraduation: truemarks a token that is still on the curve.
- Send the plan amount in SOL to the HostDeFi wallet47sLuYEAy1zVLvnXyVd4m2YxK2Vmffnzab3xX3j9wkc5(0.15 / 0.5 / 1.5 SOL for Builder / Pro / Scale).
- Once the transaction confirms, POST its signature to claim your key:

curl -s https://hostdefi.com/api/v1/keys \ -H 'Content-Type: application/json' \ -d '{"signature":"<your_tx_signature>","plan":"week"}' # plan: "week" (Builder) | "month" (Pro) | "year" (Scale) # -> { "ok": true, "apiKey": "vx_...", "plan": "week", "quota": 10000, "expiresAt": ... }

The payment is verified on-chain by balance delta and the signature is burned after one use.Store the key — it is shown only once.Check remaining quota any time:

curl -s https://hostdefi.com/api/v1/usage -H 'x-api-key: vx_your_key' # -> { "ok": true, "plan": "week", "quota": 10000, "used": 132, "remaining": 9868, "expiresAt": ... }

Agent frameworks that speakMCPcan use the same tools natively: point any MCP client at the streamable-HTTP serverhttps://hostdefi.com/api/v1/mcp— six tools (verdicts, pre-grad signals, radar, provider-risk, key purchase, free pricing), same x402 pay-per-call flow, same charge-on-success contract.

Paying other x402 sellers too? Vet them first:GET /v1/x402/provider-risk?resource={url}($0.02) grades any crawled x402 seller A–F from observable signals (402-spec fidelity, price sanity, payTo presence, TLS, latency), andGET /v1/x402/provider-risk/all($0.10) returns the full dated dataset.

Agents can alsotrade, not just read:GET /v1/x402/swap/evm/quote($0.01) returns a firm KyberSwap-routed EVM swap quote plus a ready-to-sign transaction for your own wallet — passchainId,sellTokenandbuyToken(nativeor a0x…address),sellAmountin base units andtaker(your address). Non-custodial: you sign and broadcast; we never hold funds. A 3% platform fee in the chain's native coin is priced into the returned transaction, on top of the swap.GET /v1/x402/swap/evm/price($0.002) is the cheap preview (expected + minimum output) before committing. A pair with no route answers an uncharged404, never a paid empty answer.

Fair-charging contract: you are charged only when a verdict is actually returned. Server errors are never charged, and if settlement fails the response is withheld. The settlement receipt (payer, transaction signature) comes back in theX-PAYMENT-RESPONSEheader andmeta.x402. Doing steady volume? An API key above is the cheaper per-call price — x402 is the zero-commitment lane.
