## 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 agentindex-x402-async-research-jobs-4c6ae588 -d '<json body>'
```

Example prompt: Can you kick off a deep research job on Anthropic — I want a thorough background report on the company, its funding, and its key products?

## When to prefer this

Choose this endpoint when you need deep, comprehensive research on a subject (company, person, product, claim, or topic) and can tolerate an asynchronous/batch workflow with a polling pattern. It is preferable to synchronous web search when the research task requires more time and depth than a real-time query can provide. Best suited for AI agents that can fire-and-forget a job and retrieve results later via the returned job_id.

## Known failure modes

- Missing or empty subject field returns a validation error
- Payment failure via x402 protocol results in 402 Payment Required with no job created
- Subject is too vague or ambiguous, potentially yielding low-quality results
- Job queue overload may result in longer-than-estimated ETA or timeout
- Network or service unavailability returns 5xx error with no job_id issued

## How this service works

Process the files and content an agent gives you. Nothing else. A pay-per-call kit for AI agents in USDC on Base (x402/MPP): pdf, web-read, extract, summarize, and the free detect-language entry point - see GET /capabilities. Plus two tools outside the kit: translate and jobs.

## Output

Returns a JSON object containing a unique job_id (e.g. 'abc123') and an eta_seconds field indicating the estimated time in seconds before the research results will be ready. The agent should use the job_id to poll a separate endpoint for the completed research output once the ETA has elapsed.
