# Author Detect Bulk

> Author Detect 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).

Detects article authors and bylines for up to 20 URLs in a single concurrent batch call, returning results in input order with per-item error fields.

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 author-detect-bulk-20bb7d81
```

Example prompt: I have a list of 15 article URLs and I need to know who wrote each one — can you run a bulk author and byline detection across all of them at once and tell me if any fail?

## When to prefer this

Use this endpoint when you have a list of 2–20 article URLs and need author/byline data for all of them in a single API call with concurrent processing and ordered results. It is more efficient than calling the single /site/author endpoint in a loop, especially when latency and cost matter. Prefer this over the single endpoint whenever you hold a batch of URLs from a content pipeline, press monitoring report, or link aggregator.

## Known failure modes

- URL is unreachable or returns a non-200 status — per-item error field set, failure count incremented
- Page has no detectable author or byline — per-item result empty or error flagged
- Batch exceeds 20 URLs — request may be rejected or truncated
- Malformed URLs in input — per-item error returned for affected items
- Paywalled or JavaScript-rendered pages may prevent author extraction

## How this service works

Bulk author detect: 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/author endpoint (Article author and byline detection). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of results matching the input URL list, where each item contains the detected article author name and byline (same fields as the single /site/author endpoint), plus a per-item error field if detection failed, and a top-level count of total failures across the batch.
