# x402 Proof Lift Report

> x402 Proof Lift Report is a paid API for AI agents from x402-market-intel-mcp.mtree.workers.dev, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).

Generates a paid-call telemetry and marketplace rank report showing route proof coverage, index/rank movement, buyer-query lift, and next bounded proof action for an x402 API discovery campaign.

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 x402-proof-lift-report-a50d08cf -d '<json body>'
```

Example prompt: Pull the proof lift report for my x402 route at api.example.com/v1/chat — show me the current route proof coverage, how my index rank has moved recently, and what the next recommended proof action is.

## When to prefer this

Choose this endpoint when you need to assess the real-world discovery performance of a specific x402 paid API route — combining paid-call proof telemetry with marketplace rank signals into one actionable report. Prefer this over general API analytics when your primary concern is x402 campaign visibility, proof coverage, and rank movement in the x402 paid-service ecosystem.

## Known failure modes

- Invalid or unrecognized x402 route identifier returns 404 or empty report
- Payment not processed (x402 USDC payment failure on Base) returns 402 error
- Route has no historical telemetry data resulting in sparse/empty report
- Marketplace rank observations unavailable for very new routes
- Network timeout on the workers.dev hosted endpoint

## How this service works

Hosted proof-lift report for x402 paid API discovery campaigns: combines paid-call telemetry with recurring marketplace rank observations to show route proof coverage, index/rank movement, buyer-query lift, and the next bounded proof action. Price 0.20 USDC on Base via x402. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/proof_lift_report. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.

## Output

Returns a structured proof lift report containing: route proof coverage metrics, index and rank movement over time, buyer-query lift data from paid-call telemetry, recurring marketplace rank observations, and a concrete next bounded proof action recommendation for the x402 discovery campaign.
