Extract Numbers for Agents API for agents
Extract numbers from free text. Call when scraping prices, IDs, quantities, or scores out of messy agent-collected text. Returns the ordered list of numbers found—no LLM, no regex maintainance on your side. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
