# canonical-check-bulk

> canonical-check-bulk 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 the canonical URL for up to 20 URLs in a single batch call, returning results in input order with per-item errors and a failure count.

## Facts

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 canonical-check-bulk-a0fc7375
```

Example prompt: Can you check the canonical URLs for all 15 pages in my list at once and tell me which ones have issues or unexpected canonical tags?

## When to prefer this

Use this endpoint when you have a list of URLs (up to 20) and need to check canonical tags for all of them efficiently in one call rather than making separate single-URL requests. Prefer this over the single /site/canonical endpoint whenever you are processing multiple URLs to save on latency and API calls. Ideal for SEO audits, pre-launch checks, or any workflow where canonical correctness needs to be verified across a batch of pages.

## Known failure modes

- Invalid or unreachable URL returns a per-item error with a failure reason
- Exceeding 20 URLs in a single call may result in a request rejection
- Network timeouts for individual URLs are captured in per-item error fields, not as a full batch failure
- Malformed input (non-URL strings) may cause per-item errors
- Payment failure or missing x402 payment header results in a 402 response for the entire batch

## How this service works

Bulk canonical check: up to 20 urls 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 /site/canonical endpoint (Canonical URL check). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results (one per input URL) each containing the detected canonical URL for that page, a per-item error field if the check failed, and an overall count of how many items failed across the batch.
