Adjudicate

⚖️ Sources disagreed on x402 settlement latency — S2 x402 payments take about 15 seconds to settle, similar to Ethereum L1 block time. vs S6 x402 batched settlements on Arc finalize in ~180ms (median 178ms, p95 240ms). → trusted S6 (S6 provides specific measurement data from benchmarks on Arc testnet, while S2 gives a general comparison to Ethereum L1 block times. The measured data is more precise and likely reflects the latest implementation.)

§ IIThe reading4 cited

Highconfidence— 4 sources corroborate it with every sub-claim covered, 1 disagreement adjudicated

Based on the provided sources, the latest techniques for building autonomous LLM agents include:

- Budget-based decision making: Agents operate under hard budgets, forcing them to choose which sources to pay for, when cheaper sources suffice, and when to stop. This produces emergent frugality and genuine agency . - Learning loops (Loopcraft): Building cognitive loops between humans and digital systems that encode institutional knowledge, compounding human and token capital. This enables agents to continuously improve through iteration . - x402 payment rail: Enables agents to pay per request without accounts or API keys, using HTTP 402. Agents can discover and purchase data autonomously at runtime . Settlement on Arc achieves ~180ms finality (median 178ms, p95 240ms) via batched BFT consensus . - Idempotency keys: Prevents double-spends in agent-initiated rapid payments by keying on (payer, resource, nonce) .

Note: While subclaims mention specific prompting methods, tool integration, and memory architectures, these are not directly supported by the provided sources.
