# Agent402 Market Brief Research Report

> Agent402 Market Brief Research Report is a paid API for AI agents from agent402.tools, paid per call via x402, $0.85/call, status unknown (last checked 2026-09-14).

Generates a synthesized, cited market research report on any financial or agentic-technology topic by running multiple web searches and distilling results into a structured report.

## 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 agent402-market-brief-research-report-d4e18cac -d '<json body>'
```

Example prompt: Can you pull together a market brief on leading agentic payment protocols — focus on stablecoin rails and x402 adoption — and format it as a markdown report using only sources from the past year?

## When to prefer this

Choose this endpoint when you need a synthesized, multi-source research report with citations rather than a single web lookup or data point. It is especially well-suited for market landscape questions, competitive analysis, and emerging technology overviews in the agentic finance and AI tooling space. Prefer it over generic search APIs when you need the results distilled into a coherent narrative with ranked, cited sources. It is not suited for real-time price data, structured database lookups, or queries requiring deterministic computation.

## Known failure modes

- Query exceeds 2000 characters — request rejected with validation error
- Recency filter too narrow returning insufficient sources — report may have fewer citations
- Payment of $0.85 USDC not completed — 402 Payment Required response
- Invalid format enum value — defaults to markdown or returns validation error
- Focus array exceeds 8 items — request rejected
- Synthesis model timeout on complex queries — partial or empty report returned

## How this service works

Name a market, category or company and get one cited MARKET / COMPETITOR BRIEF: how the market is defined and sized, the key players and what each offers, pricing, recent moves, how they differ, risks and a bottom line - every claim from live web research with citations, nothing from memory. The research pipeline with a competitive-intelligence plan. USDC (x402/MPP) or card (Stripe). Not cached.

## Output

A structured JSON response containing: a markdown (or JSON) research report with inline citations, a list of cited sources with URLs, relevance ranks, titles and snippets, a list of sub-questions explored during research, and metadata including the number of searches run, sources consulted, sources cited, and the synthesis model used.
