10 x402-paywalled Robinhood Chain endpoints — KOL trades, hot tokens, leaderboards, token snapshots, buyer-quality, KOL-consensus, risk scores, holder census, wallet PnL and deployer alerts. Your agent's wallet is the key: no signup, no subscription. Pay a flat $0.04 in USDG on Robinhood Chain, or $0.005–$0.02 in USDC on Solana — settled in ~1 second.
Settles on Robinhood Chain via EIP-3009 transferWithAuthorization. Flat $0.04 minimum per call. Best if your agent already operates on RHC.
Settles on Solana at the base price ($0.005–$0.02). Best if your agent already holds Solana USDC — the same rail as the Solana x402 API.
| Endpoint | USDG (RHC) | USDC (Solana) |
|---|---|---|
/api/x402/rhc/kol/feed KOL trade feed Real-time trades from tracked Robinhood Chain KOL wallets — 0x addresses, ETH amounts, tx hashes, enriched with live market cap, deployer tier, and MC-multiple-since-trade. | $0.04 | $0.005 |
/api/x402/rhc/kol/hot-tokens Hot tokens (KOL consensus) Tokens bought by 2+ tracked KOLs inside the window — the consensus-buy signal, enriched with launchpad, deployer tier, graduation status, and current MC. | $0.04 | $0.01 |
/api/x402/rhc/kol/leaderboard KOL leaderboard KOL activity ranking by trades, buy/sell ETH volume, net flow, and tokens traded over 24h / 7d / 30d. | $0.04 | $0.005 |
/api/x402/rhc/tokens/{mint} Token snapshot Metadata + live price / market cap / FDV, liquidity, pool inventory, deployer reputation, and named KOL activity for any RHC token. | $0.04 | $0.01 |
/api/x402/rhc/tokens/{mint}/buyer-quality Buyer quality Quality score for a token's earliest buyer cohort — win-rate, KOL presence, bot-domination, bundle penalty, and the OOS-validated dump-cluster ensemble. Full parity with the Solana scorer. | $0.04 | $0.02 |
/api/x402/rhc/tokens/{mint}/kol-consensus KOL consensus How the tracked KOL cohort is positioned on a token: distinct buyers/sellers, exit rate, net ETH flow, median entry MC, first-touch wallet — with the full buyer/exit wallet lists. | $0.04 | $0.02 |
/api/x402/rhc/tokens/{mint}/risk Token risk score 0–100 rug/safety score with a per-factor breakdown, a live on-chain sell simulation (honeypot check), LP-removal and deployer flags — the call an agent makes right before it buys. | $0.04 | $0.02 |
/api/x402/rhc/tokens/{mint}/holders Holder census Top holders with wei-exact balances, cumulative concentration, LP / deployer / KOL labels and a supply reconciliation block — folded from our own node, nothing sampled. | $0.04 | $0.02 |
/api/x402/rhc/wallet/{address}/pnl Wallet PnL FIFO cost-basis PnL for any Robinhood Chain wallet: realized + unrealized, per-token positions, daily curve. | $0.04 | $0.02 |
/api/x402/rhc/deployer-hunter/alerts Deployer alerts Launch alerts from tracked, graded deployers — tier, lifetime bond rate, market cap at alert. The Solana deployer-hunter, on Robinhood Chain. | $0.04 | $0.01 |
Responses match the exact shape of the equivalent /api/v1/rhc/* endpoints.
# 1. Discover the catalog (free) curl https://madeonsol.com/api/x402/rhc # 2. Call an endpoint — returns HTTP 402 with the payment challenge curl -i https://madeonsol.com/api/x402/rhc/kol/feed?limit=20 # 3. Your x402 client signs the payment and retries; you get the data. # Pay with USDG on Robinhood Chain, or USDC on Solana — your choice.
Or let the SDK do the signing — both handle the 402 → sign → retry flow, one USDG payment per call, and expose the on-chain settlement:
# TypeScript — npm install robinhood-chain-x402 viem
import { createKeylessClient } from "robinhood-chain-x402";
const agent = createKeylessClient(process.env.RHC_PAYER_KEY); // EVM wallet holding USDG on chain 4663
const risk = await agent.tokenRisk("0xd0601ce157db5bdc3162bbac2a2c8af5320d9eec"); // NVDA, $0.02
console.log(risk.score, agent.lastPayment?.transaction);
# Python — pip install "robinhood-chain[x402]"
from robinhood_chain import RobinhoodClient
agent = RobinhoodClient(private_key=os.environ["RHC_PAYER_KEY"])
print(agent.token_risk("0xd060...9eec")["score"], agent.last_payment["transaction"])A pay-per-call HTTP API for Robinhood Chain (an Arbitrum Orbit L2, chain id 4663) memecoin data — KOL trade feed, hot tokens, leaderboard, token snapshots, buyer-quality, KOL-consensus, risk score, holder census, wallet PnL and deployer alerts. It uses the x402 protocol: your AI agent calls an endpoint, gets an HTTP 402 with a payment challenge, signs a micropayment from its own wallet, and receives the data. No account, no API key, no subscription.
Both. Every endpoint advertises two payment options (x402 accepts[]): USDG on Robinhood Chain (native, via EIP-3009 transferWithAuthorization) or USDC on Solana. Your agent pays with whichever it holds. The USDG-on-RHC leg has a $0.04 floor; the Solana-USDC leg keeps the base price.
$0.005–$0.02 per call on the Solana-USDC leg, or a flat $0.04 minimum on the USDG-on-Robinhood-Chain leg. There is no monthly minimum and no signup.
USDG (Global Dollar) is a Paxos-issued, EIP-3009-compatible stablecoin and the dominant stablecoin on Robinhood Chain. Because it supports transferWithAuthorization, an agent can authorize a single exact-amount payment with one signature — the gasless flow x402 needs.
Yes. The /api/x402/rhc/* responses share the exact shape of the equivalent /api/v1/rhc/* endpoints — real 0x addresses, real tx hashes, full precision. No downgrade for paying per call.
GET https://madeonsol.com/api/x402/rhc returns the full catalog as JSON — paths, prices, both payment options, and schemas — for agent self-configuration. It is free and requires no payment.
