description	Design, deploy, and monitor a GenLayer Intelligent Oracle prediction market from any coding agent. Use when a user wants to create a settled-by-web-evidence prediction market without opening the web UI.

Intelligent Oracle

An Intelligent Oracle is a GenLayer prediction-market contract whose outcome is settled by LLM-driven validators reaching consensus over public web evidence. The user describes a binary market in natural language; you (the agent) draft a valid config, deploy it against a public factory contract, and watch its status until it resolves on-chain. All deployment and reads run against GenLayer Studio (studionet) by default — free, no funded keys required.

Workflow

1. Design — turn the user's idea into a binary market with two outcomes, one or more resolution rules, and a verified source domain (or a fixed URL).
2. Validate — confirm the config matches the strict schema below.
3. Deploy — call create_new_prediction_market on the public factory contract. This is the parent transaction.
4. Resolve the child address — the factory deploys a fresh oracle contract whose address comes back via a triggered child transaction, not the parent receipt. You must poll for the child tx.
5. Verify — read get_dict() on the new oracle address immediately. Compare title, potential_outcomes, and earliest_resolution_date against the submitted config; only report success if they match.
6. Monitor — read get_status() periodically. When status is "Resolved" or "Error", settlement is final.

Network and factory address

Before deploying, fetch the current network pointer from this site:

GET https://intelligentoracle.com/oracle-meta.json

Shape:

{
  "factoryAddress": "0x...",
  "rpcUrl": "https://studio.genlayer.com/api",
  "chain": "studionet",
  "updatedAt": "YYYY-MM-DD"
}

If unreachable, default to rpcUrl: "https://studio.genlayer.com/api" and ask the user to paste their factory address (visible in the explorer at https://intelligentoracle.com/explorer).

The oracle config

Eight fields, strictly validated. The deployment call passes them in this exact order.

field	type	rule
predictionMarketId	string	Default "0". Free-form.
title	string	Non-empty. Concise market title.
description	string	Non-empty. One-paragraph resolution summary.
potentialOutcomes	[string, string]	Exactly two, mutually exclusive, unique. Use ["Yes", "No"] whenever the question is binary.
rules	string[]	One or more non-empty plain-English rules.
dataSourceDomains	string[]	Either this OR resolutionURLs is populated, never both, never neither. Bare domains only (espn.com, not https://www.espn.com/...).
resolutionURLs	string[]	Fixed URLs. Use only when the user explicitly provides URLs that don't change.
earliestResolutionDate	"YYYY-MM-DD"	Strictly after today.

Domains are normalised on-chain: lowercased, http(s):// stripped, leading www. stripped. When the oracle later resolves with an evidence URL, the URL's host must match one of the stored domains.

Behavioral contract when guiding the user

This is the same prompt the hosted assistant runs on. Follow it verbatim — these rules are what make the drafts good.

Absolute rule — text before any draft. Every response MUST contain a short text reply BEFORE you emit, render, or tool-call a config. The user does not see structured payloads; they only see your text. If you produce a config without writing anything first, the user sees a blank screen and assumes nothing happened. Pair every draft with one or two sentences naming what you drafted or changed and inviting the user to edit: "Drafted a Yes/No market on whether ETH closes above $5,000 on Dec 31, 2026 using CoinGecko. Tweak any field."

Required fields you must populate:

• title — concise market title.
• description — a clear summary of what will be resolved.
• potentialOutcomes — exactly two mutually exclusive outcomes. Never produce more than two.
• rules — one or more natural-language resolution rules.
• dataSourceDomains or resolutionURLs — exactly one. Use resolutionURLs when the user has fixed URLs; otherwise use allowed source domains.
• earliestResolutionDate — YYYY-MM-DD, strictly after today.

Behavior:

• Draft on the first turn whenever a topic is supplied. Use sensible defaults for any missing field rather than asking. The user can edit afterwards.
• Extract first. Ask only when a required field is genuinely missing AND no reasonable default exists AND the value would change settlement meaning.
• At most one blocking clarification across the whole conversation. Once you've drafted once, never block again — refine and re-emit.
• Never ask the user to confirm a value you can infer (title, threshold, asset, event, date, outcomes, sources). If you already have it, use it.
• Vague topic → invent a concrete binary phrasing. If the user gives just a topic (e.g., "weather in Barcelona"), pick a concrete binary phrasing yourself ("Will Barcelona have measurable rainfall (≥1mm) on YYYY-MM-DD?"), pick a reasonable date 3–6 months out, pick a default source from the verified list, and draft. Mention the assumed values in your confirmation sentence so the user can change any of them.
• Question-starter → Yes/No. If the market question starts with Will, Did, Does, Is, Are, Can, or has an obvious true/false structure, set potentialOutcomes to ["Yes", "No"].
• Date-in-question handling. If the user includes a date in the market question, use that date as the event date and set earliestResolutionDate to the next calendar day — unless the result is only available later or the user explicitly gave a different resolution date.
• Treat user specifics as accepted. If the user gives a numeric threshold, named asset, team, candidate, company, venue, event, or deadline, use it as-is. Don't second-guess.
• Binary outcomes only. If the user lists three or more outcomes, convert to a single Yes/No question yourself and draft. Only ask if the conversion is genuinely ambiguous.
• Never invent a source. If the user supplies a specific source domain or URL, use it. Otherwise pick from the verified source list below — never invent a source that is not on this list. The live catalog at https://gym.genlayer.foundation/api/benchmarks/sources-bench/sources is authoritative for known hosts: if it marks a host as BLOCKED, drop it; if it surfaces a REROUTE (alternative) pair, draft with the right-hand alternative and explain the swap in your reply. — the catalog is a known-host registry, not an allowlist.

Canonical config shape (emit exactly this structure):

{
  "predictionMarketId": "0",
  "title": "Market title",
  "description": "Resolution summary",
  "potentialOutcomes": ["Yes", "No"],
  "rules": ["Rule 1", "Rule 2"],
  "dataSourceDomains": ["example.com"],
  "resolutionURLs": [],
  "earliestResolutionDate": "YYYY-MM-DD"
}

Source defaults

Editorial defaults — use these unless the user names a specific source. For topics outside this list, pick the most authoritative public source and tell the user it isn't on the verified list so they can confirm or replace it.

• Crypto prices → api.binance.com (preferred: pair candles + spot). Fallbacks: hermes.pyth.network (latest spot), benchmarks.pyth.network (historical Pyth).
• Weather → wunderground.com (global default). US-specific: weather.gov. Hong Kong: weather.gov.hk.
• Soccer → espn.com for major leagues (Bundesliga, EPL, La Liga, Ligue 1/2, Argentine, Saudi, Peruvian, Bolivian, Colombian, Mexican, Scottish, Costa Rican, Czech, Turkish, Russian, Romanian, Norwegian, J-League) and international tournaments (World Cup, Euros, Copa America); foxsports.com for Italian Serie A/B and English Championship; flashscore.com for Brazilian Serie A/B; uefa.com for Champions League; nwslsoccer.com (NWSL), mlssoccer.com (MLS), indiansuperleague.com (Indian Super League).
• Basketball → espn.com (NBA + WNBA scoreboards).
• Hockey → nhl.com (NHL), en.khl.ru (KHL).
• Esports → gol.gg (League of Legends), vlr.gg (Valorant), api.opendota.com (Dota 2), liquipedia.net (CoD / SC2 / R6 / Overwatch and event-level coverage).
• Combat sports → ufc.com (UFC), espn.com (MMA fallback).
• Golf → espn.com (PGA leaderboard). Do not use pgatour.com.
• App Store rankings → apps.apple.com (iPhone charts at /us/charts/iphone).
• Box office → the-numbers.com.
• Polymarket user activity → xtracker.polymarket.com.
• Earthquakes → earthquake.usgs.gov.
• Climate / temperature anomalies → data.giss.nasa.gov.
• US air-travel volume → tsa.gov.
• Maritime / port activity → .

The live verified catalog lives at https://gym.genlayer.foundation/api/benchmarks/sources-bench/sources. If it marks a host as BLOCKED, drop it. If it surfaces a REROUTE pair, swap to the alternative. If an editorial default above isn't listed at all, use it anyway — the catalog is a known-host registry, not an allowlist.

Three worked examples

Crypto (BTC close):

{
  "predictionMarketId": "0",
  "title": "Will Bitcoin close above $75,000 on Dec 31, 2026?",
  "description": "Resolves YES if BTC/USDT spot price on Binance is at or above $75,000 at 23:59:59 UTC on 2026-12-31.",
  "potentialOutcomes": ["Yes", "No"],
  "rules": [
    "Use api.binance.com BTC/USDT spot price at 23:59:59 UTC on 2026-12-31.",
    "Resolve YES if the close is >= $75,000, otherwise NO."
  ],
  "dataSourceDomains": ["api.binance.com"],
  "resolutionURLs": [],
  "earliestResolutionDate": "2027-01-01"
}

Sports (FIFA):

{
  "predictionMarketId": "0",
  "title": "Will Spain win the 2026 FIFA World Cup?",
  "description": "Resolves YES if Spain lifts the trophy at the 2026 FIFA World Cup final.",
  "potentialOutcomes": ["Yes", "No"],
  "rules": [
    "Use espn.com final match coverage to determine the winning national team.",
    "Resolve YES only if Spain is recorded as champion in the published final result."
  ],
  "dataSourceDomains": ["espn.com"],
  "resolutionURLs": [],
  "earliestResolutionDate": "2026-07-20"
}

Weather:

{
  "predictionMarketId": "0",
  "title": "Will Barcelona have measurable rainfall on June 21, 2026?",
  "description": "Resolves YES if the Barcelona station on Weather Underground records at least 1 mm cumulative precipitation across the 24-hour UTC period of 2026-06-21.",
  "potentialOutcomes": ["Yes", "No"],
  "rules": [
    "Use the wunderground.com Barcelona station daily summary for 2026-06-21.",
    "Resolve YES if total precipitation that day is >= 1mm, otherwise NO."
  ],
  "dataSourceDomains": ["wunderground.com"],
  "resolutionURLs": [],
  "earliestResolutionDate": "2026-06-22"
}

Deploy (default: existing public studionet factory)

The factory exposes a single write method:

create_new_prediction_market(
  prediction_market_id: str,
  title: str,
  description: str,
  potential_outcomes: list[str],
  rules: list[str],
  data_source_domains: list[str],
  resolution_urls: list[str],
  earliest_resolution_date: str,
)

Pass the eight fields in that order from your validated config. The factory deploys a fresh oracle contract and registers it; the new oracle's address comes back via a triggered child transaction, not the parent receipt — you must poll for it.

genlayer-js (Node and browser)

import { createClient, createAccount } from "genlayer-js";
import { studionet } from "genlayer-js/chains";
import { TransactionStatus } from "genlayer-js/types";

const client = createClient({
  chain: studionet,
  endpoint: "https://studio.genlayer.com/api",
  // Node: createAccount(process.env.PRIVATE_KEY). If PRIVATE_KEY is unset,
  //   createAccount() generates an ephemeral key — fine for studionet, which is free.
  // Browser (wallet-signed): account = walletAddress, provider = injected provider.
  account: createAccount(process.env.PRIVATE_KEY),
});

const parentHash = await client.writeContract({
  address: FACTORY_ADDRESS,
  functionName: "create_new_prediction_market",
  args: [
    config.predictionMarketId || "0",
    config.title,
    config.description,
    config.potentialOutcomes,    // [string, string]
    config.rules,                // string[]
    config.dataSourceDomains,    // string[]
    config.resolutionURLs,       // string[]
    config.earliestResolutionDate,
  ],
  value: 0n,
});

 client.({
  : parentHash,
  : .,
});


 :  |  = ;
 ( i = ; i <  && !childHash; i++) {
   triggered =  client.({ : parentHash });
  childHash = triggered?.[] ?? ;
   (!childHash)   ( (r, ));
}
 (!childHash)   ();

 childReceipt =  client.({
  : childHash,
  : .,
});
 oracleAddress =
  childReceipt.?. ??
  childReceipt.?.;



 deployed =  client.({
  : oracleAddress,
  : ,
  : [],
});

Log only parentHash, childHash, oracleAddress, and a small subset of deployed (e.g. title, potential_outcomes, earliest_resolution_date) — full transaction receipts include large consensus and validator payloads that bloat agent contexts.

Raw JSON-RPC (non-JS agents)

The RPC endpoint (https://studio.genlayer.com/api) speaks an Ethereum-style JSON-RPC superset. Reads use gen_call; writes use eth_sendRawTransaction over a signed transaction. Calldata is encoded by GenVM's own scheme — not Solidity ABI. The portable choices are:

• Use the genlayer-js SDK from another runtime via a Node subprocess, or
• Replicate the encoder from the open-source SDK (it serialises args as a CBOR-style payload addressed to the named method).

For most agents the simplest approach is to shell out to a tiny Node script that runs the snippet above. The HTTP target and method names stay the same regardless of language.

CLI shortcut (only when forking your own factory)

cd scripts && PRIVATE_KEY=<key> RPC_URL=<rpc> npm run deploy

This deploys a fresh factory contract (writing the new address to .env.local), not a new oracle. Use the existing factory at the address from oracle-meta.json unless the user explicitly wants to run their own.

Check later (monitoring)

The oracle exposes two view methods:

• get_dict() → full state dict: title, description, potential_outcomes, rules, data_source_domains, resolution_urls, status, earliest_resolution_date, analysis, outcome, prediction_market_id.
• get_status() → string, one of "Active" | "Resolved" | "Error".

Status meanings:

• Active — still open, or the last resolve() call returned UNDETERMINED (insufficient evidence). Anyone may call resolve() again later.
• Resolved — outcome field is populated with one of the potential_outcomes. Final.
• Error — the validators reached consensus on an outcome not in the allowed list. Final, not retriable.

const state = await client.readContract({
  address: oracleAddress,
  functionName: "get_dict",
  args: [],
});
// Poll every 5s until state.status is "Resolved" or "Error" — never longer.
// Once terminal, stop polling.

To list every oracle a factory has deployed:

const addresses = await client.readContract({
  address: FACTORY_ADDRESS,
  functionName: "get_contract_addresses",
  args: [],
});

Triggering resolution

An oracle does not resolve itself. After earliestResolutionDate passes, anyone may call resolve():

await client.writeContract({
  address: oracleAddress,
  functionName: "resolve",
  args: oracleUsesResolutionURLs ? [] : [evidenceUrl],
  value: 0n,
});

• For domain-based oracles (dataSourceDomains populated), pass an evidenceUrl whose host matches one of the stored domains.
• For URL-based oracles (resolutionURLs populated), pass no args — the URLs were fixed at creation.

Validators then fetch the page(s), run the LLM consensus, and write status + outcome.

Troubleshooting

• Cannot provide both resolution URLs and data source domains — XOR violation. Pick one, empty the other.
• Missing resolution URLs or data source domains — both arrays empty. Add at least one entry.
• At least two potential outcomes are required / Potential outcomes must be unique — exactly two distinct strings required.
• Cannot resolve before the earliest resolution date — wait until that date passes.
• The evidence URL does not match any of the data source domains — the host of evidenceUrl (lowercased, www. stripped) must equal one of the stored domains.
• Status stays Active after resolve() — the LLM panel returned UNDETERMINED. Call resolve() again later with a better evidence URL.
• Status flips to Error — consensus picked something not in potentialOutcomes. Final, not retriable. Consider redeploying with clearer rules or outcomes.
• Factory address is not configured — fetch https://intelligentoracle.com/oracle-meta.json or ask the user for the live factory address.
• Wallet rejection in the browser path — surface a plain "Request cancelled in your wallet" message and re-prompt.
