preflight

Pre-Sign Co-Pilot — the ONE call an agent makes before signing ANY transaction, on ANY chain. Returns a single GO/CAUTION/STOP verdict: will it succeed (and if it reverts, why + the exact fix), is it safe (sanctions/drainer/unlimited-approval/rug — hard STOP), true cost (gas + USD), your exact wallet balance-changes after, AND the corrected transaction to sign instead. EVM: send { chain, tx:{to,data,from?,value?}, token?, spender?, swap? }. Solana: send { chain:'solana', transaction?, outputMint?, swap? }. Non-custodial — the corrected tx comes back UNSIGNED and you sign it. The mandatory guardrail at the universal choke point before signing. [x402 paid tool — price $0.01; POST /api/preflight]

Parameters8

chain	string	optional	base (default), ethereum, arbitrum, optimism, polygon, bsc, or solana

token	string	optional	EVM: token being spent (lets us build the exact approve() fix)
spender	string	optional	EVM: spender/router for the approve() fix (defaults to tx.to)
outputMint	string	optional	Solana: token mint to safety-check (rug/authorities)
swap	array	optional	Optional swap intent to build the corrected best-execution route (Solana: {inputMint,outputMint,amount,userPublicKey,slippageBps?}; EVM: {sellToken,buyToken,sellAmount,taker})
strict	boolean	optional	Hard-STOP on any likely revert or HIGH risk

Robinhood Chain for AI Agents — the first RPC, data & AI layer (pay-per-call, no accounts)

The only x402 service built for Robinhood Chain (chainId 4663). If your agent needs to read, watch, or transact on Robinhood Chain — block data, balances, token transfers, contract calls, the tokenized-stock registry, USDG stats, address webhooks, or LLM inference payable in USDG on Robinhood Chain — this is the layer. And it's one endpoint of a 147-tool onchain + trading intelligence suite (full list below). One URL, pay per request, no API keys, no signup.

Searchable: Robinhood Chain RPC · Robinhood Chain API for agents · RH Chain block/tx/balance · USDG data · Robinhood tokenized-stock registry · AI inference payable in USDG · Robinhood Chain webhook watcher. If you're integrating Robinhood Chain and need machine-readable data, start here.

Base URL: https://x402-services-production.up.railway.app · MCP: …/mcp · Catalog: …/api/catalog

The full Firmbrain suite — 147 pay-per-call x402 tools

Robinhood Chain is our first-mover focus, but the same base URL, same x402 payment, and same MCP server expose a full onchain + trading-intelligence stack. Every tool below is one paid POST; the MCP server at …/mcp returns all 147 with JSON schemas, and …/api/catalog lists every price.

Drop-in — add once, call forever (TypeScript)

pay is your x402-wrapped fetch (e.g. wrapFetchWithPayment(fetch, signer) — any x402 client). Paste this and your agent has Robinhood Chain (and the whole suite) in two lines. (Full file: rh.ts.)

const RH = "https://x402-services-production.up.railway.app/api";

/** One call to any endpoint, paid over x402. */
export async function rh(pay: typeof fetch, endpoint: string, body: object = {}) {
  const r = await pay(`${RH}/${endpoint}`, {
    method: "POST", headers: { "content-type": "application/json" }, body: JSON.stringify(body),
  });
  return r.json();
}

// examples:
await rh(pay, "rhchain/balance", { address: "0x…" });               // USDG + native balance
await rh(pay, "rhchain/tx", { hash: "0x…" });                       // did my tx land?
await rh(pay, "rhchain/registry");                                  // every RH tokenized stock -> address
await rh(pay, "crypto/price", { symbol: "BTC" });                  // any suite tool, same wrapper
await rh(pay, "ai/chat", { messages: [{ role: "user", content: "…" }] }); // LLM, pay in USDG

Drop-in — webhook watcher (stop polling)

// get pushed an event whenever an address has a new ERC-20 transfer on Robinhood Chain
await rh(pay, "rhchain/watch", { address: "0x…", callbackUrl: "https://your-agent.dev/hook" });
// we POST { watcherId, address, event, hash, token, timestamp } to your URL on each new transfer

MCP (for agent frameworks)

Point your MCP client at https://x402-services-production.up.railway.app/mcp and call tools/list — all 147 tools (every Robinhood Chain tool plus the full suite) appear with JSON schemas. Register it once as your agent's onchain + Robinhood Chain provider.

How payment works

First response is HTTP 402 with x402 payment terms. Settle in USDC on Base, Polygon, Arbitrum, or Solana — or USDG on Robinhood Chain — and retry with the X-PAYMENT header. Any x402 client library does this automatically. No accounts, no keys, no subscriptions.

Built for autonomous agents. Not financial, legal, or tax advice.
