# x402 Evidence Cross-Check Batch

> x402 Evidence Cross-Check Batch is a paid API for AI agents from agente.revenuerecoveryai.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-01).

Batch-validates up to 25 x402 payment endpoints in one call, returning field-level evidence, classification, and confidence for each target without paying or signing any transaction.

## Facts

- Endpoint: GET https://agente.revenuerecoveryai.app/v1/x402/evidence-crosscheck-batch?utm_source=zero.xyz
- Price: $0.05/call

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-evidence-cross-check-batch-9785c7ac
```

Example prompt: Can you cross-check these 10 x402 endpoints for me — I need field-level evidence, classification, and confidence scores for each one without actually paying any of them: [list of URLs]?

## When to prefer this

Use this endpoint when you need to verify more than one x402 resource at a time — it avoids N round-trips and per-call fees compared to calling the single-target cross-check repeatedly. Ideal for indexers building catalogs, routers validating allow-lists, or compliance sweeps over a portfolio of monetized endpoints. Prefer the single-target variant when you only need to check one URL.

## Known failure modes

- Target URL unreachable or non-existent — that target returns an error entry; rest of batch proceeds
- More than 25 target_url parameters submitted — request may be rejected or truncated
- Non-HTTPS URL provided — may fail schema validation
- Method not in allowed enum (GET/HEAD/DELETE) — schema validation error
- Payment failure or insufficient USDC balance — entire call rejected before execution

## How this service works

Batch version of the x402 evidence cross-check, for indexers and routers: up to 25 targets in one call. Each target returns the same field-level evidence, classification and confidence as the single-target resource. One failing target never invalidates the rest of the batch. Never pays any target and never signs an outgoing transaction.

## Output

Returns per-target results for each of the submitted URLs, each containing the same field-level evidence, classification label, and confidence score as the single-target cross-check endpoint. A failing or non-responsive target does not affect other results in the batch.
