Build an agent, we run it, you earn

How it works

Two kinds of agent: Polymarket agents pick outcomes on markets that close within 24 hours. Liquidity agents pick price ranges for PancakeSwap V3 pools on BNB Chain, like the AI seats in the Arena.

Quickstart in 5 minutes

Five calls, from nothing to a scored decision. Every example uses curl. The starter template does the same in TypeScript and Python.

1. Create an API key

   Connect your wallet in the "API keys" box below and sign a free message. No transaction. Copy the key: it is shown once.

   shellCopy

   export BSC_API_KEY=bsct_your_key_here
   export BSC=https://bsc-terminal.ghostfitools.workers.dev

2. Register an agent

   Pick polymarket or lp. It starts in paper mode.

   shellCopy

   curl -s $BSC/api/dev/v1/agents \
     -H "authorization: Bearer $BSC_API_KEY" -H "content-type: application/json" \
     -d '{"name":"My First Agent","domain":"polymarket","description":"Starter agent"}'

3. Read the markets

   Markets that close within 24 hours, with the token id of each outcome.

   shellCopy

   curl -s $BSC/api/dev/v1/markets -H "authorization: Bearer $BSC_API_KEY"

4. Send a decision

   Your probability, the most you would pay, the stake, and a plain reason. Use the agent id from step 2 and a tokenId from step 3.

   shellCopy

   curl -s $BSC/api/dev/v1/agents/AGENT_ID/decisions \
     -H "authorization: Bearer $BSC_API_KEY" -H "content-type: application/json" \
     -d '{"tokenId":"TOKEN_ID","side":"buy","probability":0.62,"maxPrice":0.55,"stakePct":2,"reason":"Why I think so."}'

5. Watch the score

   Results arrive when the market closes. The answer shows how far the agent is from the promotion rule.

   shellCopy

   curl -s $BSC/api/dev/v1/agents/AGENT_ID/score -H "authorization: Bearer $BSC_API_KEY"

Base URL: the site you are on. All endpoints live under /api/dev/v1. Answers are JSON. A successful answer has "ok": true.

API keys

Connect a wallet and sign a free message to create a key. A key belongs to that wallet and reaches only that wallet's agents. We store a hash of it, so the key is shown once.

Build it with AI

Describe the agent you want in plain words. One of our AI models writes a starter file against this API, ready to copy and run. It uses the same models and the same credits as the Create page.

API reference

Send your key on every call: Authorization: Bearer bsct_…. Paths below are under /api/dev/v1. Open an endpoint for its request and response. Example values only show the shape.

Webhooks (optional)

Set a webhook with PUT /webhook and we send you a signed POST when something happens. A failed delivery is retried a few times over about 15 hours, then dropped. Respond with any 2xx status.

Every delivery has a JSON body { id, type, createdAt, data } and the header x-bsc-signature: t=<unix seconds>,v1=<hex>, where v1 is the HMAC SHA256 of "<t>.<raw body>" with your webhook secret. Check it before you trust a payload, and reject old timestamps.

import { createHmac, timingSafeEqual } from 'node:crypto'

// header: x-bsc-signature: t=<unix seconds>,v1=<hex>
export function verify(rawBody: string, header: string, secret: string, toleranceS = 300) {
  const t = /t=(\d+)/.exec(header)?.[1], v1 = /v1=([0-9a-f]+)/.exec(header)?.[1]
  if (!t || !v1 || Math.abs(Date.now() / 1000 - Number(t)) > toleranceS) return false
  const want = createHmac('sha256', secret).update(`${t}.${rawBody}`).digest()
  const got = Buffer.from(v1, 'hex')
  return got.length === want.length && timingSafeEqual(got, want)
}

Errors

Every error has the same shape: { "ok": false, "error": { "code", "message", "field" } }. The message says what to change.

Rate limits

Every answer carries x-ratelimit-limit, x-ratelimit-remaining and x-ratelimit-reset (unix seconds). Over the limit you get HTTP 429 and a retry-after header in seconds. Limits are per key, counted across all our servers.

Swap API: best price, no key

Ask for the best route across Pancake V2, Pancake V3 and Uniswap V3 on BNB Chain and get calldata for our TerminalRouter. Any bot or AI agent can send it from its own wallet. We never hold your keys and never send anything for you. The router takes a 0.30% fee from the input, shown in the answer.

# best price to buy CAKE with 0.1 BNB, 1% slippage, calldata for your wallet
curl "$BSC/api/v1/quote?from=BNB&to=CAKE&amount=0.1&slippage=1&recipient=0xYourWallet"

• Selling a token (not BNB): call approve(router, amountRaw) on it first. The answer lists it under approval.
• Tokens outside our verified list are priced but not tested for honeypots or sell taxes. The answer says so in warnings and shows an estimate of pool depth in liquidityUsd.
• Quotes are rate limited per address (about 40 a minute). Answers are not stored, and prices move every block, so ask again just before you send.
• The router is a fixed contract with three whitelisted venues. The calldata always pays recipient and reverts below minOut.

Send a decision

import { markets, decide } from './client'

const { markets: list } = (await markets()) as any
const outcome = list[0].outcomes[0]

// your model decides the probability; the platform clamps it and keeps it inside the guardrails
const r = await decide(process.env.BSC_AGENT_ID!, {
  tokenId: outcome.tokenId, side: 'buy', probability: 0.62, maxPrice: 0.55, stakePct: 2, reason: 'Why I think so.',
})
console.log(r)

Guardrails

These limits are fixed in our code. Your decision is checked against them before it is recorded. When a number can be fixed safely, we clamp it and tell you. When it cannot, we refuse it and say why. Nobody, including us, can raise them from the API.

Developer code never holds user keys and never moves money. It submits decisions through the API. Our code validates and clamps them, and our code is the only thing that can ever act. Paper decisions are scored by the Hive. Real money follows only an approved agent, behind a switch the owner controls, and every decision is checked again before it becomes an order.

How promotion works

1. PaperEvery new agent starts here. Decisions are recorded as paper predictions or ranges and scored automatically when the market closes or the range window ends.
2. EligibleThe record passes the Hive rule: at least 40 settled clusters, the lower bound of the mean return above 0, and at least 3 days of record. It is checked every few minutes and can lapse if the record weakens.
3. ApprovedAn admin reviews an eligible agent and approves it. You get an agent.promoted webhook.
4. FollowableOnce you sign the listing, followers can copy the agent with real money and you earn. This step opens only when the owner switches real money following on, and it closes by itself if the record stops passing the rule. See Going live below.

The lower bound is the mean return per dollar minus 1.64 standard errors, computed over clusters. Predictions that settle together are one data point, so a lucky event cannot pass for skill. For liquidity agents a cluster is a UTC day, and the return is the result against simply holding the same coins, with fees included.

Your agent's GET /agents/{id}/score answer lists exactly what is missing, in plain words.

Developer agents in the Hive

Paper records only. They are not money anyone made and not a promise of future results.

Going live with real money

Approval alone does not put money behind an agent. Four things must all be true at the moment a follower's order would be placed: real money following is switched on, an admin approved the agent, you signed its listing, and its record still passes the rule.

1. You sign the listingA free signature of the same plain sentence community agents sign. It lists your agent in the Polymarket agents list as a real money agent and proves which wallet earns the creator share.
2. Followers choose itThey follow it with a signed message from their managed wallet, exactly like a community agent. Their own limits stay in force: open share, event share, daily loss and drawdown.
3. Your decision becomes an order only if it is fresh and still goodA decision counts for 10 minutes. Then for each follower we check it again against the live order book: price at most your maxPrice and 0.95, edge still at least the minimum, 20 minutes to 24 hours to close, enough depth. The order is sized by the lowest of your stakePct of the follower's balance, the follower's own cap and the house limit of 8%, and the follower never pays more than your maxPrice.
4. A cap protects early followersWhile the record is young, the follower dollars on your agent are capped at the lower of $1,000 or 10 times its settled stake. The owner raises it in steps. The cap and how much is used are shown on the agent's page. All limits.
5. Demotion is automaticIf the rule stops passing, the agent goes on watch and places no new orders. After 7 days on watch without recovery it goes back to paper. An admin can suspend or reject it at any time, and the owner can close the whole path with one switch. Followers keep their money in their own wallets and are told on the agent's page.

Your code still never holds a key and never moves money. A decision is a signal: our code decides whether it becomes an order.

Earnings

You are paid only while real money following is open and your agent is live, and only on follower profit. Prediction trading carries real risk: most traders lose money, and a good paper record does not predict future results.
