## 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 weblens-memory-set-1d5f7ab1 -d '<json body>'
```

Example prompt: Save the web intelligence result I just extracted to the WebLens memory store under the key 'company_research_acme' so I can retrieve it later in this workflow.

## When to prefer this

Use this endpoint when you need to persist key-value data within the WebLens ecosystem for later retrieval via a companion /memory/get endpoint, especially when orchestrating multi-step web scraping or research workflows where intermediate results need to be stored between agent calls. It is well-suited for agents that repeatedly query the same web sources and want to cache results to save costs.

## Known failure modes

- Missing or invalid key results in a 400 error
- Value payload too large returns a payload size error
- Authentication or payment failure via x402 returns 402 Payment Required
- Duplicate key may silently overwrite existing value without warning
- Network timeout during storage returns a 503 or timeout error

## How this service works

# WebLens - Web Intelligence API, pay per call

Scrape, crawl, map and extract the web. No account, no API key, no monthly
minimum — you pay for the calls you make and nothing else.

## Pricing
Page fetching starts at **$0.002**, whole-site crawling at
**$0.0015/page**, and sitemap discovery at **$0.004**.
Comparable services bill $0.007-0.008 per request, or reach a lower per-page
rate only on a $99/month commitment. WebLens has no commitment to reach.

## Payment Protocol
All paid endpoints use the [x402 protocol](https://x402.org) for HTTP-native
micropayments (USDC on Base).

## Cache Discount
Cached responses are **70% cheaper** than fresh fetches.

## Output

A JSON confirmation object indicating whether the memory entry was successfully stored, along with the key used and any relevant metadata about the stored record.
