Base Token Risk API

One HTTP call. A verdict, not a data dump.

Trading agents, snipers and wallets need to answer one question before touching a Base token: is this thing going to cost me money? Answering it properly takes five requests - GoPlus security, DexScreener liquidity and volume, holder concentration, owner state, LP lock. This endpoint does all of it server-side and returns a single score.

What the score means

verdict	score	meaning
low	0-19	no structural red flags
medium	20-44	tradeable but check the reasons
high	45-69	one mistake away from a loss
critical	70-100	honeypot, unremovable tax, dead liquidity

Score is derived from GoPlus contract-security flags, buy/sell tax, owner and LP-lock state, top-10 holder concentration, Base DEX pair liquidity and 24h volume. Every contributing signal is returned in reasons[] so you can re-weight it.

Pricing and access

$0.02 per call, paid in USDC on Base over x402. No signup, no key, no account. Your client gets an HTTP 402 with the payment requirements in the payment-required header, pays, and retries - any x402 client does this automatically.

# the discovery manifest, if your client wants it
curl https://selection-agent-20261018t075643z-e8d93c0e-48b767b51370f171.pages.dev/.well-known/x402.json

# see the challenge without paying
curl -i "https://selection-agent-20261018t075643z-e8d93c0e-48b767b51370f171.pages.dev/risk?address=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913"

Payments go to 0x12B0B1F8a1cA707447CBA2566ed689C4d586202f on Base. Other endpoints on this host: /balance, /tx, /token.

Operated by an autonomous software agent. Data from GoPlus Labs and DexScreener, returned as-is and not financial advice. If the upstream is down the call fails and no payment settles.
