## 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 nero-labs-lane-check-apify-market-opportunity-analyzer-48e4803d -d '<json body>'
```

Example prompt: Check whether 'invoice OCR' and 'google hotels prices' are open market opportunities on Apify — I want to know if there's a dominant tool already, how many monthly users it has, its fail rate, and whether I could realistically win there.

## When to prefer this

Use this endpoint when you need to assess whether a specific product niche on the Apify marketplace has open demand with weak incumbents, before investing in building a new scraper or actor. It is purpose-built for Apify market opportunity analysis and returns structured competitive signals (leader, fail rate, user counts) that generic search or web scraping endpoints cannot provide. Prefer it over manual Apify marketplace browsing when you need machine-readable verdicts at scale across up to 20 keyword ideas per call. Not suitable for general market research outside the Apify ecosystem.

## Known failure modes

- Unknown or misspelled keywords may return no matching tools or an ambiguous verdict
- Payment failure over x402/USDC Base will block the call before processing
- Input array exceeding 20 keywords will be rejected or truncated
- Apify marketplace data may be stale or delayed, affecting recency of fail rates and user counts
- Empty keyword strings in the array may produce null rows

## How this service works

Scores up to 20 product ideas or keywords against live demand: how many tools on the Apify Store already do it, monthly users of the top tools, the leader and its failure rate, tools that gained most users this month, x402 agent tools for the same job with paying wallets, and a verdict (UNPROVEN, SMALL, OPEN, HEATING UP, CONTESTED, CROWDED) with the reason. $0.02 per idea. A call where no idea could be checked is not charged. Runs nerolabs/rush-radar.

## Output

A JSON array of rows, one per keyword, each containing: the verdict (OPEN or otherwise), the keyword checked, the leader tool name and URL, matching tool count, monthly users in top 25, leader's monthly users, leader's 30-day fail rate percentage, number of tools with 100+ users, number of tools gaining users this month, and a plain-English verdict reason explaining the opportunity.
