# Maha Source-Bound Research Microbrief

> Maha Source-Bound Research Microbrief is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.24/call, status unknown (last checked 2026-10-26).

Retrieves and extracts exact short quotes from up to three approved, rights-reviewed public text sources to answer one narrow question, returning a bounded extractive brief with source links, locators, retrieval hashes, and explicit unknowns.

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 maha-source-bound-research-microbrief-37c0bcbf -d '<json body>'
```

Example prompt: Using only these two public sources — [URL1] and [URL2] — find me exact quotes that answer this question: 'What are the main causes of coral reef bleaching?' Treat it as public data and give me a bounded brief with source links and any gaps noted.

## When to prefer this

Choose this endpoint when you need a verifiable, citation-grounded answer to a narrow question drawn strictly from sources you specify — with no risk of model hallucination or invented content. It is ideal when auditability, exact quotes, and retrieval hashes matter (e.g. compliance, legal, fact-checking contexts). Prefer it over open-ended research tools when you already have approved source URLs and need bounded, rights-reviewed extraction rather than broad web search or generative summarization.

## Known failure modes

- Source URL not accessible or not rights-approved — returns error or empty result for that source
- Question exceeds 300 character limit — schema validation error
- Fewer than 1 or more than 3 sources provided — schema validation error
- Source contains no relevant extractive content for the question — limitation noted in output
- Network timeout retrieving source — failure flagged per source
- Invalid dataClass enum value — schema validation error

## How this service works

Retrieve up to three approved, rights-reviewed public text sources for one narrow question. Return a bounded extractive brief with exact short quotes, source links, locators, retrieval hashes and explicit unknowns. No model calls, invented answer, semantic contradiction detection, open-ended research or factual certification.

## Output

A bounded extractive microbrief containing: exact short verbatim quotes from up to three sources, source links with content locators, a retrieval hash per source, a result hash, an input hash, a receipt digest, and a structured limitations list noting what the sources do not cover or what could not be confirmed. No synthesized or invented content is included.
