Data providers & APIs

Hoodini reads a lot of sources so you don't have to. Here's every external provider we use and exactly what it powers — and the rule that ties them together: when a provider is down, rate-limited, or simply doesn't know, the signal it feeds reads unknown. We never guess to fill a gap.

On-chain

• Robinhood Chain RPC — the chain itself. Sellability simulation, pool balances and routability, the deployer's transaction count, and composing the swap transactions for one-click trading. Reads only; the chain is the source of truth for anything about your money.
• Alchemy — indexed log streaming and archival reads. This is how the watcher spots a launch the moment it graduates, and a WebSocket feed carries every token transfer into or out of a tracked trader's wallet the block it lands, so the copy book sees a buy in about two seconds. A paid provider, so we lean on the DB first and call it deliberately: the live price feed follows live positions only, and the paper books mark from the market price and a sell quote, which is what their results were always measured on. We also watch our own monthly usage and step down to the public node before the provider can cut us off — background reads first, and the live book last of all. Slower, never stopped, and the state is public on the status page.
• Uniswap (on Robinhood Chain) — the venues behind in-app trading, both versions. v3: QuoterV2 for quotes, SwapRouter02 for the swap. v4 (where pools.trade launches graduate): the V4 Quoter for quotes and the Universal Router — with Permit2 for approvals — for the swap. The token's deepest real pool is resolved live from the chain at trade time.

Signals & security

• Blockscout (Builder plan) — the Robinhood Chain explorer API: holder counts, the top-holder list behind the bubble map and concentration, and contract-source verification. Credit-metered, so a daily guard stops holder/source reads when the budget runs low rather than overspending.
• GoPlus Security — token-security checks: honeypot flag, buy/sell tax, whether the contract is mintable, and owner privileges (can the owner reclaim ownership or pause transfers).
• Arkham Intelligence (arkm.com) — entity intelligence on Robinhood Chain: labels for wallets and deployers (exchanges, launchpads, funds, named entities), the "smart money" and notable-holder callouts, and funding-source tracing that ties deployers funded from the same wallet into the sybil ring graph. Cached hard and budget-guarded.

Copy trading

• fomo (fomo.family) — the app the tracked traders use. Its public 30-day leaderboard is where the shortlist comes from, re-read every six hours; each handle's profile gives us the trader's account address. Trader names link to their fomo profile everywhere.
• Relay (relay.link) — the execution network fomo's buys travel through. Relay's public request record names the app that created a request, who it was for and what was paid; it is how a Relay fill is told apart from a delivery. See How we know a buy is a buy.
• Telegram Bot API — the public channel's cards and the bot's private messages. Outbound only; the bot never asks anything of you.

Market data

• GeckoTerminal — price, market cap / FDV, pool liquidity, 24-hour volume, and the minute-candle OHLCV price chart. The keyless API rate-limits our server's IP, so calls are paced and adapt to it.
• CoinGecko — the same on-chain market data, used as a fallback: when a GeckoTerminal call is rate-limited, we retry it through CoinGecko so freshness doesn't stall. Budget-capped so it stays within the free plan.
• DexScreener — the DEX paid and boost badges and the Paid board; a token's pairs and their age for the copy book's gates, and its price as the sanity check on every chain quote and the fallback mark when a pool drains.

Accounts & platform

• Privy — sign-in (Google, X, email, passkey) and the non-custodial embedded wallet created for you. Only you can move its funds or export its key.
• Cloudflare Turnstile — a privacy-preserving bot check on scanning and comments, so those stay abuse-resistant without tracking you.

Why list this at all

Because the whole product is about honesty over hype — magic? no, just numbers and bytes. Every number you see traces back to one of these sources, and every gap is marked as a gap. If a provider changes or an outage shows up in the data, you'll see it as unknown, not as a confident wrong answer.
