wet_resolveResolve prediction-market listings to a canonical claim identity
Parse listings you supply into a structural claim identity — or refuse, naming the rule that stopped and what would close the gap.
Live · Keyless · Read-only
Give your agent
the prediction markets.
One MCP server for every real-world event trading across Kalshi, Polymarket and Gemini — what it is, which venues carry it, what each outcome is priced at, and the news attached to it. No key, no account, no OAuth step.
Server URL
https://www.worldeventtrading.com/api/mcp
Run this in your terminal — it writes the config for you.

No API key, no account, and no OAuth step — the public tools are keyless by construction. Ask your assistant “what prediction markets are live on the Fed decision?” to confirm it connected.
5 tools · all read-only
What your agent can ask
The tools chain: search for the event, then drill into its markets or its news. None of them can place, route, or hold an order — W.E.T. is not an exchange and the server carries no execution surface at all.
wet_benchmark_valueRead published W.E.T. benchmark index values
Published W.E.T. benchmark index values and their full settlement history. Free and attributed, by standing commitment.
wet_search_eventsSearch real-world events across prediction-market venues
Start here. Find real-world events across venues by text, category or venue. Returns venue coverage, volume with its unit, a matched headline, and the id the next call takes.
wet_event_marketsRead every venue market on one event, with prices
Every venue market on one event, with implied probabilities and the volume basis each venue reports in.
wet_event_headlinesRecent news matched to the events it concerns
The news wire matched to the events it concerns — for answering “what is moving, and why” without guessing which story belongs to which market.

What the answers do not mean
Every one of these was a measured failure mode before it was a rule. They ride in the payloads and in the server instructions, so a model never has to infer them — and they are the reason this data is worth wiring into something that will repeat it to a person.
Venue coverage is not equivalence
Two venues on one event means both list something W.E.T. grouped there — by matchup, tournament and date, not confirmed contract identity. Measured true cross-venue overlap is 1.3–1.5%. An agent that reads a venue count as an arbitrage will report a trade that does not exist.
Volume carries a unit
Polymarket reports USD, Kalshi reports contracts. Every volume field ships with its basis, and unlike bases are never summed into a total.
A probability with no named outcome is withheld
Where a venue titles its market the same as the event, the price cannot be attributed to a side — so the field is null and carries the reason instead of a number that reads as the favourite’s.
A refusal is an answer
When W.E.T. declines, the payload says which rule fired and what would close the gap, and carries no value field at all — never a null standing in for a number, never a zero, never a carried-forward reading.
Pricing
The data is free. It stays free.
Every published benchmark value, settlement row, constituent list and intraday indicative is free, unauthenticated and attributed — a standing commitment that takes 90 days' notice to change. The public tools on this page are keyless by construction, not by configuration: there is no gate to flip.
What Premium buys is reach and throughput, and it is live now: an API key adds tools over your watchlists and saved views, opens the same surface over authenticated REST, and raises the quota to 5,000 requests an hour. A key never changes, gates, or improves a single tool on this page — it only appends account-scoped ones. Delivery guarantees and commercial redistribution rights are still ahead of us, and named here rather than sold early.
Outputs are market-derived measurements and identity determinations. They are not predictions, recommendations, or trading advice, and W.E.T. is neither a broker nor an investment adviser.
