# Macaroon Network – Polymathica Campaigns Index Search

> Macaroon Network – Polymathica Campaigns Index Search is a paid API for AI agents from api.macaroonnetwork.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Searches a governed corpus of 1,131 scientific hypothesis proposals across five rigor tiers, returning full honesty/lifecycle metadata for each result

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 macaroon-network-polymathica-campaigns-index-search-63eb126d -d '<json body>'
```

Example prompt: Search the Polymathica campaigns index for hypothesis proposals related to quantum cognition — I want to see results across all rigor tiers including exploratory and speculative, and show me the full lifecycle and validation status for each one.

## When to prefer this

Use this endpoint when you need to discover and explore scientific hypothesis proposals with full governance transparency — particularly when rigor tier classification and lifecycle/validation honesty fields matter. Prefer this over general web search when you want a curated, governed corpus free of quarantined (metaphysical/non-physical) records and need structured metadata like promotion_eligible status alongside each result.

## Known failure modes

- Empty result set if query terms do not match any of the 1,131 indexed proposals
- Malformed POST body returns a validation error
- Corpus is fixed at 1,131 records — queries for topics outside the indexed scope will return no results
- Rate limiting or payment failure (x402) if USDC payment is not properly attached
- Network timeout if the endpoint is temporarily unavailable

## How this service works

Searches a governed corpus of 1,131 scientific hypothesis proposals across five rigor tiers (benchmark, established_method, active_research, exploratory, speculative). Every record is IDEA-tier and unvalidated — this is a discovery layer over proposals, not results. Quarantined records (not_physical, metaphysical) are excluded at the source. Returns full honesty fields (execution_status, validation_status, promotion_eligible, lifecycle_state, governor_reason) with every result.

## Output

Returns a list of matching hypothesis proposal records from the 1,131-record governed corpus, each including: the proposal content, rigor tier classification (benchmark, established_method, active_research, exploratory, speculative), and full honesty fields (execution_status, validation_status, promotion_eligible, lifecycle_state, governor_reason). Quarantined records (not_physical, metaphysical) are excluded.
