How this service works
Paid data APIs for AI agents: prediction-market analytics, weather intelligence, weather×market edge signals, and SEC/gov data. Paid endpoints use the x402 protocol (HTTP 402 + USDC on Base): call without payment to receive requirements, retry with an X-PAYMENT header. Machine-readable catalog: /llms.txt. Per-endpoint docs: /docs/{id}.
Output
A JSON object containing the aggregated implied probability (0-1 scale) that ETH closes above $5,000 at year-end, per-venue breakdowns (Polymarket, Kalshi) with individual implied probabilities, 24-hour USD volume, and liquidity scores, plus the 1-hour price move, resolution date, divergence between venues, and metadata including data freshness (realtime) and a unique request ID.
Example use cases
Crypto portfolio risk assessment
“What's the current market-implied probability that ETH ends the year above $5,000? I want to factor the consensus odds into my portfolio rebalancing decision.”
Trading signal monitoring dashboard
“Check the live prediction market probability for ETH closing above $5k EOY and tell me how much it has moved in the last hour.”
Research briefing on ETH price outlook
“Pull the aggregated Polymarket and Kalshi odds for Ethereum finishing 2026 above $5,000, including the 24-hour volume and liquidity score so I can gauge how reliable the signal is.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/evergreen/eth-above-5k-eoyWhen to prefer
Choose this endpoint when you need a single, real-time aggregated probability for ETH's year-end price from prediction markets, especially when you want cross-venue comparison (Polymarket vs Kalshi) and liquidity metadata in one call. Prefer this over scraping individual prediction market sites or using price-feed APIs that only give spot prices rather than market-implied probabilities.
Side effects
- 402 Payment Required if no X-PAYMENT header is provided — response contains payment requirements for USDC on Base
- Payment amount or token mismatch returns payment error
- Market may temporarily be unavailable if upstream prediction market venues are down
- Stale data if upstream liquidity is low or venue is paused
