# compression-check-bulk

> compression-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 HTTP compression (gzip/brotli/deflate) for up to 20 URLs in a single concurrent batch call, returning per-item results in input order with error fields 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 compression-check-bulk-d20bbe1f
```

Example prompt: Can you check whether HTTP compression (gzip or brotli) is enabled on all 15 of these websites at once and tell me which ones are missing it?

## When to prefer this

Choose this endpoint when you have a list of 2–20 URLs and need to check HTTP compression for all of them efficiently in a single API call. It is preferable over calling the single /site/compression endpoint repeatedly because all items are processed concurrently and results are returned in input order with consolidated error handling. Ideal for bulk audits, CI/CD pipelines, or agent workflows enriching a dataset of URLs.

## Known failure modes

- Invalid or unreachable URLs return per-item errors without failing the entire batch
- URLs that time out are counted in the failure total
- Malformed input (wrong type or method) returns a 400-level error
- Batch exceeds 20 URLs — request is rejected
- Sites blocking automated requests may return false negatives

## How this service works

Bulk compression 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/compression endpoint (HTTP compression check). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of per-item results matching the input URL order, each containing the detected compression type (e.g. gzip, brotli, deflate, none), compression status, and a per-item error field if the check failed. A top-level failure count summarizes how many items errored across the batch.
