# DJZS verify_pm_trade — Prediction Market Trade Thesis Auditor

> DJZS verify_pm_trade — Prediction Market Trade Thesis Auditor is a paid API for AI agents from mcp.djzs.ai, paid per call via x402, $2/call, status unknown (last checked 2026-09-15).

Extracts claims from a free-text prediction market trade thesis and scores them against a frozen taxonomy of reasoning failures, returning a verdict, fired flags with evidence, a risk score, and a reproducible hash.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability djzs-verify-pm-trade-prediction-market-trade-thesis-auditor-adbf5cc0 -d '<json body>'
```

Example prompt: Can you audit my Polymarket trade thesis for reasoning quality? Here it is: 'I'm going YES on the Fed cutting rates by July. Polymarket has this at 42%, but Kalshi has it at 51%. My falsification condition is if the June CPI print exceeds 3.5%. My edge is that the market underweights labor market softening data from Q1.' Write it to my on-chain trust record at 0xAbC123...

## When to prefer this

Use this endpoint when an agent or trader needs to audit the epistemic quality of a prediction market trade thesis — not just wallet safety or transaction validity — before committing capital. Prefer this over generic fact-checkers or spell-checkers when the specific concern is reasoning failures like missing falsification conditions, unsourced probabilities, narrative/resolution gaps, or false edge from consensus. Choose this when you want a reproducible, hashable verdict tied to a frozen taxonomy, or when you need a permanent on-chain trust record of trading decisions via Base.

## Known failure modes

- Out-of-scope request refused without charge — no payment taken
- Thesis lacks required fields (claim, probability, falsification) causing HALT action with halt_reason explaining missing elements
- Malformed or empty intent string returns FAIL action
- Invalid EVM address for agent_address causes trust_score write to fail with error_class detail
- Payment settlement failure on x402 layer prevents audit from completing
- Network issues with Base for on-chain trust record write result in trust_score status error

## How this service works

DJZS audits the thesis, not the transaction. Wallet-layer tooling checks whether a transfer is safe; nothing checks whether the reasoning behind it holds. verify_pm_trade extracts the claims from a free-text trade thesis and scores them against a frozen taxonomy (narrative/resolution gap, falsification absent, probability unsourced, consensus-as-edge), returning a verdict, the codes that fired, a risk score, and a hash anyone can recompute from the submitted text. Out-of-scope requests are refused free: no payment settles.

## Output

Returns a JSON object with: a verdict (PASS/WAIT/FAIL/null), an action directive (PROCEED/HALT/FAIL), an array of fired taxonomy flags each containing a code (e.g. DJZS-M03), name, severity, weight, and verbatim evidence quote from the submitted text, an aggregate risk_score (0-100), frozen taxonomy and weight hashes for reproducibility, a settlement record of the x402 payment, and optionally a trust_score object with on-chain write status and transaction hash if an agent_address was provided, or a halt_reason explaining what information is missing.
