Animica Forecast — AI-Powered Prediction Market Forecaster
x402
Animica Forecast — AI-Powered Prediction Market Forecaster is a paid API for AI agents from animica.dev, paid per call via x402, $0.002874/call, status unknown (last checked 2026-09-14).
Answers a yes/no question about the future using an AI model, optionally anchoring the prediction against a real-world prediction market, and returns a cryptographically anchored probability with reasoning and proof.

How this service works
Ask a yes/no question about the future and get three things: an independent model probability, the live price of the matching prediction market when one exists, and — the point of the product — the whole record anchored into the Animica data-availability layer with a commitment anyone can verify FREE and permanently at GET /x402/forecast/{commitment}. Anyone can claim afterwards that they called it; this proves what was believed beforehand. Both numbers are always returned side by side: the model is NOT claimed to beat the market, and our own accuracy against every resolved market is published free at GET /x402/forecast/calibration, including when we lose. If the record cannot be anchored the call fails rather than selling an unanchored prediction.
Output
Returns a JSON object containing: a commitment hash and verify_url for the anchored prediction; record (exact anchored bytes); model object with probability (0–1), reasoning text, and model name; market object (if a market was matched) with current price, market id, slug, end date, and source or null; divergence between AI probability and market price; anchored_at with blockchain head height and hash; proof bytes; and an explicit statement of what the proof does and does not establish.
Example use cases
Election outcome probability estimate
“What's the probability that a third-party candidate wins a US Senate seat in the 2026 midterms? Give me an AI forecast with your reasoning for the question 'Will a third-party candidate win a US Senate seat in the 2026 midterms?'”
Tech event deadline forecast
“How likely is it that OpenAI releases GPT-5 before January 1 2026? Use prediction market slug 'openai-gpt5-2025' to compare the AI forecast against market odds and show me the divergence.”
Geopolitical event prediction
“What's the AI's probability that NATO membership expands to include a new country before 2027? I want the full reasoning, the anchored proof, and a verification URL I can share.”

Endpoint
POSThttps://animica.dev/x402/forecastWhen to prefer
Choose this endpoint when you need a verifiable, cryptographically anchored AI probability estimate for a yes/no question about the future — especially when you want to compare the AI forecast against live prediction market odds to detect divergence. Prefer this over generic LLM querying when you need a tamper-evident proof of the prediction (anchored to a blockchain block), a structured probability score rather than a prose answer, or a side-by-side market comparison. Best suited for research, journalism, trading signal generation, or any workflow where auditability of the AI forecast matters.
Side effects
- Question is not a valid yes/no format — returns validation error
- market_id or market_slug does not match any known prediction market — market field returns null
- Blockchain anchoring service unavailable — proof or anchored_at may be missing or error
- AI model inference failure — returns server error
- Payment not processed (x402) — request rejected before inference runs
- Ambiguous or non-forecasting question causes low-confidence or malformed probability output
