# DNS vs HTTP Consistency Bulk Checker

> DNS vs HTTP Consistency Bulk Checker is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Checks DNS-to-HTTP consistency for up to 20 domains in a single concurrent batch, returning per-item results in input order with error fields and a failure count.

## Facts

- Endpoint: GET https://intel.rallylive.ca/bulk/monitor/dns-vs-http
- Price: $0.1/call
- Payment: x402

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 dns-vs-http-consistency-bulk-checker-ef2d91bd
```

Example prompt: Can you check DNS-vs-HTTP consistency for all 15 domains in my list — example.com, acme.io, store.acme.io, and the rest — and tell me which ones have mismatches and how many failed?

## When to prefer this

Choose this endpoint when you have 2–20 domains to check simultaneously and want to avoid the latency and cost overhead of serial single-domain calls. It processes domains concurrently and returns results in input order, making it ideal for bulk audits, portfolio sweeps, or pre-launch infrastructure validation. Use the single /monitor/dns-vs-http endpoint if you only have one domain to check.

## Known failure modes

- More than 20 domains submitted — batch size limit exceeded
- Invalid domain format causes per-item error for that entry
- Upstream DNS or HTTP timeout on a domain results in per-item error, not full batch failure
- Empty input list returns error
- Network unreachable for a specific domain sets per-item error field and increments failure count

## How this service works

Bulk dns http consistency: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /monitor/dns-vs-http endpoint (DNS vs HTTP consistency). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-domain results matching the input order, each containing the same DNS-vs-HTTP consistency answer as the single-domain endpoint, plus a per-item error field indicating any item-level failure, and a top-level count of how many items failed across the batch.
