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:
liteis only available forlowandmediumstake.highandcriticalalways 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:
- User says: "Swap $5K USDC for ETH because CT is bullish."
- Agent prepares the MoonPay swap request.
- Before calling
moonpay-swap-tokens, the agent sends the reasoning to ThoughtProof. - ThoughtProof returns:
- ALLOW → proceed with swap - BLOCK → stop, surface objections - UNCERTAIN → escalate, ask for clarification or review
- 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?
