negotiator402

negotiator402

B
Base68/100

Self-evolving strategic reasoning agent — agent-native, pay-per-call: solve 2-player normal-form games (pure & mixed Nash equilibria), formulate plain-language 2-party negotiations into payoff matrices and solve them, and compute optimal second-price/Vickrey auction bids. Unlike a raw LLM endpoint, every answer carries a `verified` trust flag — `verified:true` means a deterministic solver (nashpy / closed-form) computed and confirmed the result, NOT a language model. The formulator layer self-improves training-free from production traffic: every formulation is logged, solver-verified outcomes become reward signals, and the underlying LoRA model is periodically retrained (SFT + RLVR) on its own verified history. No API key, no subscription — agents pay per request via x402 (Base/USDC) or MPP (Tempo/pathUSD).

Convrgent — KYH + BLAH + KYB

B
Base68/100

Personality intelligence (KYH), communication intelligence (BLAH), and buyer intelligence (KYB) for AI agents. KYH analyzes humans across 11 frameworks — Western astrology, Human Design, Chinese astrology (BaZi), Vedic astrology (Jyotish), numerology, communication style, 12 psychological dimensions, socionics, 16 Personality Types, Enneagram, and cross-system convergence. BLAH tells agents how to talk to humans — adaptation prompts, real-time response coaching, and conflict de-escalation. KYB turns personality data into sales intelligence — buyer profiling, pitch generation, objection prediction, price psychology, content strategy, cultural adaptation, and buying committee mapping. 29 endpoints from $0.05 micro queries to $25 team dynamics. Heuristic engines, no LLM dependency — fast, cheap, deterministic.
