Map a piece of news text to the relevant Polymarket market and return its objective YES probability. Does not classify whether the news is dramatized or accurate relative to the market - that interpretation is left to the calling agent, which has both the original text and this market anchor. The probability comes from a precomputed cache refreshed on a cron cadence (can be up to ~2 hours stale) - for a live price before trading, call get_market with the returned marketId.

Look up a specific Polymarket market by id: details, live price, and an orderbook snapshot. Falls back to a direct Gamma lookup when the id is outside the precomputed cache's top markets by volume.
