## How to call it through Zero

Example prompt: Can you fact-check this claim for me: 'The SEC approved a Bitcoin spot ETF in January 2024' and tell me if it's accurate?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call AI fact-check on specific claims, statements, or regulatory assertions — particularly in crypto, RWA, SEC, or compliance contexts. At $0.001 USDC per call settled on Base, it is cost-effective for high-volume claim verification workflows where a dedicated fact-checking API with crypto-native payment rails is preferred over general-purpose LLM prompting.

## Known failure modes

- Empty or malformed properties parameter returns an error or empty result
- Ambiguous or too-short claims may produce low-confidence or inconclusive results
- Service hosted on Render free tier may experience cold-start latency or downtime
- Payment via x402/USDC on Base must succeed before response is returned; wallet or network issues will block the call
- Highly niche or very recent claims may return unverified due to knowledge gaps

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a fact-check assessment of the submitted claim or statement, potentially including a verification status (true/false/unverified/misleading), confidence score, and supporting context or source references. Response schema is minimal and may vary based on the claim type.
