Thoughtproof Reasoning Check

ThoughtProof Reasoning Check

Goal

Before executing a trade or autonomous action, verify that the agent's reasoning is sound. ThoughtProof runs adversarial multi-model critique and returns a signed verdict: ALLOW, BLOCK, or UNCERTAIN.

Prerequisites

• A funded wallet on Base (for x402 payment): mp wallet create

Usage

Check reasoning quality before a trade:

curl -X POST https://api.thoughtproof.ai/v1/check \
  -H "Content-Type: application/json" \
  -d '{"claim": "Swap $2K USDC to ETH. ETH at $2180, 6% below 30d MA, RSI 34.", "stakeLevel": "medium", "domain": "financial"}'

First call returns 402 with x402 payment details (amount, recipient, asset on Base). Pay, then retry the same request to receive the verdict.

Response

{
  "verdict": "ALLOW",
  "confidence": 0.82,
  "objections": [],
  "durationMs": 55000
}

Decision logic

| Verdict | Meaning | Action | |---------|---------|--------| | ALLOW | Reasoning passed verification | Proceed | | BLOCK | Material reasoning defects or unacceptable risk | Do not execute | | UNCERTAIN | Safe escalation state — insufficient clean evidence to justify ALLOW or BLOCK | Gather more context or require review |

Pricing

ThoughtProof pricing is stake-based.

| Stake Level | Standard | Lite | Use case | |-------------|----------|------|----------| | low | $0.01 | $0.005 | Routine low-value actions | | medium | $0.02 | $0.01 | Standard trades and service payments | | high | $0.05 | — | Large or sensitive actions | | critical | $0.10 | — | High-value or highly risky actions |

Notes:

• lite is only available for low and medium stake.
• high and critical always execute on the standard tier.
• Billing follows the executed tier, not the requested tier.

Example workflow

MoonPay + ThoughtProof: payment layer + verification layer

MoonPay handles the payment execution. ThoughtProof verifies whether the decision to pay is well-reasoned before settlement.

Example:

1. User says: "Swap $5K USDC for ETH because CT is bullish."
2. Agent prepares the MoonPay swap request.
3. Before calling moonpay-swap-tokens, the agent sends the reasoning to ThoughtProof.
4. ThoughtProof returns:

• ALLOW → proceed with swap
• BLOCK → stop, surface objections
• UNCERTAIN → escalate, ask for clarification or review

1. If verification passes, the MoonPay skill executes the swap.

Example failure:

• "Buy $50K of a token because influencers are bullish"
• ThoughtProof → BLOCK
• MoonPay execution never happens

Example pass:

• "Rebalance portfolio back to target allocation with defined slippage and stop-loss constraints"
• ThoughtProof → ALLOW
• MoonPay executes

This gives the agent stack two layers:

• MoonPay answers: can the transaction execute?
• ThoughtProof answers: should the transaction execute?
