Signals API

Every listing, delisting and rejection the moment our engine decides it, for your bot, app or agent. The site is free; the feed is paid, so it stays fast and stays ours.

$0.01per call, USDC, over x402

No key, no account. Call any endpoint; we answer 402 Payment Required with the price, your client pays and retries. You are charged only when the call succeeds.

Pay-per-call opens soon.

Wallet-only buyers can also buy a key with x402: POST /api/v1/keys/{builder|pro|desk}.

import { wrapFetchWithPayment } from "@x402/fetch";
// any x402 v2 client: it reads the 402, pays in USDC, retries
const paidFetch = wrapFetchWithPayment(fetch, client);
const res = await paidFetch("https://<this site>/api/v1/signals?after=0");

Endpoints

GET /api/v1/signals: Status changes, oldest first. Poll with after=<next> to never miss one. Filters: chain (Solana or Robinhood Chain), status, limit (max 100).
GET /api/v1/coins/{chain}/{address}: One coin's verdict: status, every check, the dev wallets we traced and each burn with its transaction hash.
Response headers: X-Credits-Remaining on key calls; PAYMENT-RESPONSE (settlement receipt) on x402 calls.

Every crypto payment goes to one wallet on Base: 0x7caB92A71D214edED4861f12ec40c12A7EDCfc81. Check it on Basescan before you pay.

Verdicts and evidence are the same ones shown on coin pages. Detection thresholds and heuristics are never exposed.
