Prices, outcomes, books, volume and liquidity share a normalized schema. Matched contracts and the arbitrage workspace help users inspect gaps together with size, venue and route context; paid history and replay support strategy research before comparison with paper behavior. The pricing page publishes concrete plans, but landing-page API waitlist language conflicts with available-now wording. Confirm the needed surface in the portal. Monthly credits meter usage separately from request-rate bursts; reading a venue does not establish that all its trading actions are supported. ### Who it is for - For developers building applications across venues and researchers comparing equivalent outcome contracts. - For teams that need historical replay and simulated orders before choosing a live execution route. ## Features and coverage - **Match and compare contracts** Compare related outcomes with normalized prices, volume, liquidity and books, then inspect spread, available size and route context in the arbitrage workspace. - **Replay and paper orders** Paid plans provide history for replay research. Paper open-order limits depend on the plan, and Pro lists up to 25 armed conditional orders. - **Developer and agent interfaces** API and SDK reduce the need to maintain separate venue adapters. The provider also documents MCP and CLI integration paths for agents. ## Workflows with Predictefy ### Budget a prototype Start with Free metadata and price reads, then estimate weighted credits for metadata, books and comparisons before upgrading. ### Validate a price gap Check settlement terms, fees, available size and quote freshness on both legs before treating matched contracts as an executable opportunity. ### Compare replay with paper behavior Choose a history window, simulate orders and compare the result with current paper trading before selecting a supported live route. ## Pricing and total cost Monthly credit allowances and request-rate limits apply separately.

Exhausted credits return 402 for metered calls; the FAQ says existing streams remain connected. 1. Read endpoint coverage and venue capabilities, then create a free portal account and API key. 2. Estimate credit usage and start with data reads or paper orders. 3. Confirm commercial licence terms before using the service in a customer-facing application. Confirm actual portal access because the landing-page waitlist and available-now pricing messages differ. ## Useful links ### What to check - Monthly plan credits reset while purchased credits persist.
