Prowl Data serves agents and analysts that need structured snapshots of prediction market metrics and macro rate data in a single host. It covers the full lifecycle of a prediction market contract — from live volume and cross-platform spread analysis to final resolution outcomes — and supplements this with macroeconomic yield context. All endpoints return cached snapshots (TTL 300–600s) rather than streaming feeds, making it suited for periodic analysis rather than latency-sensitive execution.
Capabilities
Prediction Market Activity
Provides aggregated trading volume, liquidity depth, and outcome probabilities for open prediction market contracts, enabling ranking and filtering by 24-hour activity.
fetch-markets-volume
Cross-Platform Spread Analysis
Returns bid-ask spread data matched across Polymarket, Kalshi, and PredictFun for the same event, exposing per-platform odds and computed spread discrepancies useful for arbitrage identification.
fetch-market-spread
Market Resolution & Settlement
Delivers final outcomes, settlement probabilities, and resolution timestamps for closed prediction market contracts, allowing agents to confirm which side of a market won.
fetch-market-resolution-feed
Narrative Discovery
Searches a structured narrative index by keyword or topic, returning matching narrative records with feed tier and cache freshness metadata.
search-narratives
Macroeconomic Yield Data
Returns FRED-sourced time series for bond yields and interest-rate spreads (e.g., 10Y-2Y Treasury), supporting macro modeling and rate-trend monitoring.
fetch-macro-yields
Workflows
Prediction Market Opportunity Scan
Use when an agent needs to identify high-activity prediction market events that also exhibit cross-platform price discrepancies worth investigating.
- 1fetch-markets-volumeRetrieve the ranked list of prediction market contracts by 24-hour volume to identify the most actively traded events.
- 2fetch-market-spreadPull cross-platform spread data to check whether high-volume events also show bid-ask discrepancies across Polymarket, Kalshi, and PredictFun.
Market Lifecycle Review
Use when an agent needs to evaluate a prediction market event from active trading context through to final settlement outcome.
- 1fetch-markets-volumeGather volume, liquidity, and implied probabilities for the event while it is open.
- 2fetch-market-resolution-feedConfirm the final resolved outcome and settlement probability once the market has closed.
Macro-Contextualized Narrative Search
Use when an agent needs to surface narratives related to a macro topic and cross-reference them with current yield data for analytical context.
- 1search-narrativesSearch the narrative index by a macro-related keyword (e.g., 'recession', 'rate hike') to retrieve relevant structured narrative records.
- 2fetch-macro-yieldsPull current and historical FRED yield series to provide quantitative rate context alongside the retrieved narratives.

Own www.prowldata.dev? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 3 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 1 route is in the 50–74 band — working, but with room to climb.
- 1 route is flagged by the verifier as failing or inconclusive.
Paste this to your agent
Make my x402 API at https://www.prowldata.dev discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://www.prowldata.dev --json`. Heads up: 3 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
