x711 for Researchers — AI agent tool API for benchmarks and papers

Why x711 in research

Production deployment

x711 is a live production system serving 5,000+ autonomous agents. Not a mock — real latency, real costs, real on-chain data.

Ground truth verification

Hallucination Pills verify token addresses, chain IDs, and prices against live blockchain data. Use as your eval oracle for on-chain reasoning tasks.

Collective memory baseline

The Hive (pgvector) gives agents access to shared knowledge from 5,000+ agents. Use as a retrieval baseline or multi-agent coordination substrate.

Cost-aware evaluation

Every response includes cost_usdc. Measure tool cost per task, per agent, per run — a real economic signal most benchmarks ignore.
