All calls use POST /api/agent/entrypoints/KEY/invoke with a JSON body containing input. Discovery and validation are generated by one Lucid runtime.

• get-dataset-status — free. Returns freshness, counts and exact slice IDs.
• preview-inference-chips — free. Optional sliceId; maximum five rows.
• rank-inference-chips — $0.02 testnet USDC. Required sliceId; vendor, submitter, metricView, grouping, page and pageSize filters.
• compare-inference-chips — $0.03 testnet USDC. Required sliceId, 2–8 distinct accelerator slugs and explicit baseline.

Payment behavior

This demonstration supports only Base Sepolia (chain 84532), not real USDC on Base mainnet. A configured deployment advertises x402 offers; a valid request without payment returns 402. Missing payment configuration returns 503 for paid entrypoints. Free endpoints keep working. Settlement is owned by the pinned Lucid payments extension.

Pages are a free public explorer. Paid machine endpoints are separate offerings. Do not send real funds to this demo.

Canonical discovery

Stream routes are mounted through canonical handlers; these synchronous data entrypoints do not implement streaming. Unknown keys, malformed input and unsupported modes retain Lucid error contracts.
