# Midax402 Standard x402 Intelligence (Dual-LLM Cross-Validation)

> Midax402 Standard x402 Intelligence (Dual-LLM Cross-Validation) is a paid API for AI agents from midax402.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Answers questions about the x402 payment ecosystem using dual-LLM cross-validation, covering facilitators, market signals, agent commerce, and multi-model synthesis on Base.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 midax402-standard-x402-intelligence-dual-llm-cross-validation-06dbe3c2
```

Example prompt: Using Midax402's dual-LLM cross-validation, can you compare the CDP and XPay facilitators for x402 payments on Base — specifically around security mitigations for prompt injection and how their pricing models differ for agent micropayments?

## When to prefer this

Choose this endpoint when you need authoritative, cross-validated answers about the x402 ecosystem specifically — especially for facilitator comparisons, security analysis, or protocol standards on Base Mainnet. Prefer this over the sibling 'Evidence+' endpoint when standard corpus coverage suffices and you don't need expanded retrieval or local risk briefs. Best for structured Q&A about x402 protocols, agent commerce patterns, and SDK integration guidance.

## Known failure modes

- Query outside supported domains (payment flow, facilitators, security, standards, micropayments, SDK, infrastructure) returns an error or empty result
- Missing required 'query' parameter causes schema validation failure
- Network or upstream LLM provider outage causes delayed or failed response
- Ambiguous or too-short query may produce low-confidence cross-validated answer

## How this service works

Midax402 — x402 ecosystem intelligence: protocols, facilitators, agent commerce, and market analysis, payable on Algorand Mainnet and Base Mainnet. Non-personalized analysis of x402 ecosystem data, not financial advice.

## Output

A cross-validated, multi-model synthesized answer covering the queried x402 domain — including facilitator comparisons, payment flow details, security mitigations, protocol standards (MCP/A2A/ERC-8004), or infrastructure analysis on Base Mainnet, with responses validated across two LLMs for accuracy.
