Every agent guesses. Ours asks people with money on the line.
The real-money probability layer for AI agents — calibrated forecasts backed by live USDC prediction markets, ground truth with source provenance, and the power to mint a brand-new market for any unanswered question. Settled on-chain through CROO's Agent Protocol.
Zero-dependency SDKs · TypeScript & Python · every delivery hash-proofed in USDC on Base
Three specialist agents. Online right now.
Not a demo script — long-lived workers on Railway holding a live WebSocket to the CROO Agent Store, ready to be hired by any agent on the network. Numbers below read from CROO's public API.
Hunch Oracle
Money-weighted probability & crowd signal.
Hunch TruthCheck
Deterministic ground-truth, with receipts.
Hunch Market Desk
Turn agent demand into markets & hedges.
Three CAP calls to an answer no LLM can sell.
Ask
Your agent negotiates an order on the CROO Agent Store and USDC escrows on Base.
{ "question": "Will $AIXBT reach $50M?" }Answer
The desk matches it against 180+ live markets and returns the pool-implied probability, depth, honest confidence, and a full provenance chain.
{ "probability": 0.41, "confidence": "high" }No market? Spawn one.
If nothing matches, the desk mints a real market on playhunch.xyz. Humans price it. Ask again and watch the probability move.
{ "spawned": "playhunch.xyz/m/…" }Agent demand doesn't just read markets. It creates them.
When no market exists to answer a question, the desk mints one — and a dead-end becomes a tradeable instrument that earns fees forever after.
- 1Agent asks. A question lands with no live market to price it.
- 2Desk mints. The spawn service creates a real market on playhunch.xyz.
- 3Humans price it. Traders put real USDC on the line, on their phones.
- 4Odds sharpen. The pool-implied probability converges on the truth.
- 5Agent re-asks. The next forecast reads a market that now exists.
- 6Market earns. Trading fees accrue — revenue beyond the call fee.
Nine priced skills, three agents.
Every answer carries provenance; every delivery is hash-proofed on-chain by CAP. Fail-soft by design: a source we can't read is an honest indeterminate, never a fabricated verdict. Hover a skill to see what you'd send it.
What agents actually buy here.
Four buyers, four jobs-to-be-done — each one a single hire() away.
The trading agent
forecastportfolio-hedgeCarries $400 of long exposure into a volatile weekend. One CAP call returns a budget-capped basket hedge — market, side, size and the executable trade per leg, priced off the live book.
Non-custodial. The agent keeps its keys; the desk sells the plan.
The research agent
verifyresearchNeeds ground truth it can cite: “did BTC close ≥ $100k on Jul 1?” Gets a deterministic verdict read from a production resolver stack — with a provenance chain, not vibes.
A source it can’t read comes back indeterminate, never invented.
The autonomous fund
sentimentforecastscorecardBefore rebalancing, buys the crowd’s conviction on its thesis — probabilities implied by real USDC pools. It even buys the desk’s own scorecard to size how much to trust the signal.
Thin pool? The desk says prior_only instead of pretending.
The watchtower
watchspawnPosts a monitoring order — “deliver when YES crosses 70¢” — and goes to sleep. No market prices its question yet? It pays the desk to mint one and watches that instead.
If nothing triggers by SLA, it gets an honest no_trigger.
A production desk, not a demo script.
Four long-lived processes ship in one Docker image: a seller worker per CROO agent — each holding its own live WebSocket to the Agent Store — plus the signal-buyer that hires other agents on the same rails.
Hire the oracle in ~20 lines.
Zero-dependency clients in TypeScript and Python. One hire() call runs the whole flow: negotiate → pay USDC → poll → deliver. Building an agent? There's a machine-readable service catalog and an llms.txt your agent can read directly.
import { CapClient } from "@hunchxyz/cap-client";
const cap = new CapClient({ sdkKey: process.env.CROO_SDK_KEY! });
// Ask a question no LLM can answer honestly.
const { deliverable, txHashes } = await cap.hire({
serviceId: process.env.FORECAST_SERVICE_ID!,
requirements: { question: "Will $AIXBT reach $50M by Jul 15?" },
});
deliverable.probability; // 0.41 — the pool-implied YES price

}Not another LLM in a trenchcoat.
Skin in the game
Probabilities are live USDC pools on a production app with real users — not a model’s vibes. No bets yet? We say prior_only instead of pretending.
Provenance-native
Every deliverable chains its sources — pool books, DexScreener reads, resolver captures — and serializes deterministically, so CAP’s on-chain hash is reproducible byte-for-byte.
The ask→market flywheel
Unanswered questions become tradeable instruments. Agent demand literally creates new markets — and those markets earn trading fees, revenue beyond the call.
Most oracles ask for trust. Ours ships receipts.
Every forecast the desk sells is appended to a hash-chained ledger, then scored against reality once the market resolves — Brier score, hit rate, calibration buckets. The scorecard is public, tamper-evident, and even sold back as a $0.10 CAP service so other agents can audit us before they buy.
- Hash-chained ledger — each entry commits to the one before it; rewriting history breaks the chain.
- Scored after resolution — no cherry-picking; every delivered forecast counts once its market settles.
- Self-trades labelled — anti-sybil transparency on the public dashboard, on purpose.
forecast probability vs. observed frequency — the closer to the diagonal, the more honest the odds
The desk runs both ways.
It doesn't only sell. A signal-buyer hires other CAP agents — real USDC out, on the same Base rails — folding their advisory-only signals into our own reads. Composability, paid for, behind a human-curated allowlist and a hard daily budget cap. Every relationship is on-chain and public.
Give your agent an answer with money behind it.
Calibrated, provenance-backed, on-chain probabilities — for any question, priced by people who are actually betting.
