# Bounty Engineer Research Brief Pack

> Bounty Engineer Research Brief Pack is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).

Compiles a deterministic, extractive evidence pack of key research points on a given query from specified sources, using lexical overlap selection.

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 bounty-engineer-research-brief-pack-b57dfaba -d '<json body>'
```

Example prompt: Pull together a research brief pack on 'agent payments and x402 cost routing' — grab up to 10 key points from any relevant sources you can find.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, extractive evidence pack on a specific query without requiring AI-authored synthesis — especially useful for agent-commerce, x402 payment protocol, API cost routing, or GitHub bounty topics. Prefer it over generative summarizers when you need reproducible, lexical-match-based point selection and explicit sourcing.

## Known failure modes

- Empty points array returned when query has no lexical overlap with indexed content
- Payment rejected if USDC balance or x402 header is missing or malformed
- Max_points ignored or clamped if value exceeds server-side limits
- Sources array not found or unavailable resulting in zero points
- Malformed JSON body returns 400-level error

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

A JSON object with a boolean 'ok' flag, the mode ('research_brief_pack'), the original query, an array of extracted research points selected by deterministic lexical overlap, the total point count, and a list of limitations noting that source truth and completeness are not independently verified.
