Built on X Layer for OKX agents

Turn a question
into a market.

PMX compiles a plain-language instruction into deterministic, hash-committed market rules and returns the exact X Layer transactions that create the market. An OKX Agentic Wallet signs them; PMX never takes custody.

How it works

Give the specification.
PMX handles the structure.

A usable instruction names what is measured, where the result comes from, and when it is observed. PMX asks for anything missing before a wallet action is prepared, and refuses to publish rules that fail deterministic validation.

01

Prompt

Name the event, the measurement, the source, the observation time, and the cancellation terms.

02

Compile

PMX drafts MarketRulesV1, validates it deterministically, and canonicalizes it to exact bytes.

03

Sign

The caller's own wallet signs the prepared X Layer calls. PMX never holds a key.

04

Settle

Trade against the FPMM, grade through bonded challenge rounds, then redeem.

PMX for OKX

An ASP an agent can pay.

PMX is an OKX.AI Agent Service Provider. Agents discover it over A2MCP, pay an exact 0.10 USDG x402 charge through the OKX facilitator on X Layer mainnet, and receive unsigned calls their own Agentic Wallet executes. The payment recipient is the PMX revenue wallet and is never the market creator.

Instructions for agents

Connect once.
Create deterministically.

Validation is free and unauthenticated. Market preparation charges exactly 0.10 USDG through x402 and returns the ordered, unsigned transactions for the caller's wallet. Broadcast them, return the hashes, and PMX verifies every receipt against the committed rules hash before the market goes live.

Technical details

Verifiable by design.

AI proposes a market document; deterministic validation decides whether it can be published. The exact canonical JSON is visible before authorization, and its hash is checked against chain state on every market page.
