How this service works

x402 Pulse: market intelligence and builder utilities for the x402 economy. What actually sells on x402, demand gaps, per-service traction checks, price benchmarks, payer wallet checks and a client self test, as cheap GET calls answered in under a second with explicit time information. Also on this host, ReactionPulse is an audience reaction and market research simulation for AI agents: it estimates how multiple stakeholder perspectives (customers, skeptical customers, developers, investors, competitors, early adopters, analysts, regulators, the market) would react to a product launch, announcement, price change, decision, news item, hypothesis or proposal, and returns sentiment analysis, objections, positive reactions, failure modes, market implications and recommended fixes. INPUT: JSON body {prompt (required, 8-6000 chars), context? (<=4000 chars), perspectives?[] (e.g. customer, skeptical_customer, developer, investor, competitor, early_adopter), audience?, output_language? (ISO code, default en)}. OUTPUT: strict JSON: overall_sentiment (0-100), positive_probability and negative_probability (0-1), controversy_score (0-100), perspectives[{role, stance, sentiment, headline, reasoning, top_concern, top_appeal}], likely_objections[], likely_positive_reactions[], failure_modes[{description, likelihood}], market_implications[], recommended_adjustments[], key_uncertainties[], confidence (0-1), input_integrity. TIERS: POST /v1/reaction = full analysis, 4-5 perspectives, $0.49 USDC; POST /v1/reaction/quick = 3 perspectives, compact lists, $0.15 USDC. Paid per call via x402 on Base; a free real sample is at GET /v1/example. LATENCY: full 15-30 s, quick 10-25 s (max 90 s; keep client timeouts at 120 s). LIMITATIONS: analytical LLM simulation, not a survey of real people; probabilities are estimates, not calibrated statistics; no web browsing (put relevant facts in context); one subject per call.

Output

Returns a JSON object with the wallet address, a verdict string (e.g. 'empty_throwaway'), transaction count, ETH balance, USDC balance, a boolean can_pay_usdc flag, a boolean is_contract flag, and a time object showing when the data was fetched from the live Base chain.
