# Romny Polymarket Complete-Set Edges

> Romny Polymarket Complete-Set Edges is a paid API for AI agents from api.romny.dpdns.org, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Returns predictive edge signals for Polymarket complete-set markets, optionally filtered by lane (e.g. btc-5m, eth-15m) and ask-sum threshold

## Facts

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 romny-polymarket-complete-set-edges-3d0a326c
```

Example prompt: Pull the current Polymarket complete-set edges for the btc-5m lane and only show me ones where the sum_ask is under 0.99.

## When to prefer this

Choose this endpoint when you need structured, pre-computed edge signals for Polymarket complete-set markets — particularly for crypto-linked lanes like btc-5m or eth-15m. It is more targeted than a broad market snapshot (see the sibling panel-snapshot endpoint) and is best when you want to surface actionable pricing inefficiencies in complete-set contracts, optionally pre-filtered by ask threshold.

## Known failure modes

- Invalid lane id returns empty results or error
- Threshold value outside valid range may return error or unfiltered results
- Payment failure (402) if x402 USDC payment is not properly submitted
- Service unavailable if underlying Polymarket data feed is down
- Malformed query parameters return 400 bad request

## How this service works

Polymarket complete-set predictive edges

## Output

A list of complete-set edge records for Polymarket prediction markets, each containing market identifiers, lane information, and sum_ask values indicating potential predictive inefficiencies. Results can be filtered by lane (e.g. btc-5m, eth-15m) and by a maximum sum_ask threshold.
