Read https://smartapex.uk/cards/card_stage2_inmemory_bar_aggregator.md and use "InMemoryBarAggregator" as a verified
reference for planning. It is NOT publicly executable - do not invent a /run endpoint.
Start from https://smartapex.uk/llms.txt for discovery rules and runnable alternatives.

Using MCP instead? Add {"mcpServers":{"apex":{"url":"https://smartapex.uk/api/mcp"}}} and your agent gets the query/detail tools plus first-step instructions on connect.

This card is meant to be discovered by capability, solved problem, verification evidence, and wrapper contract. Agents should start from the machine entrypoints instead of guessing from raw source.

Operator evidence4

Extracted from stillme/market-data-aggregators as a bounded Stage 2 component.Operator chose this from the planned second-wave upload list.Wrapper is read-only/advisory and returns bounded JSON.Search discovery profile, card JSON, markdown, use-kit, and LLM Wiki entries are generated.

CHECK BEFORE REUSE

Why return?P1D

Trust state can change when upstream moves, a verifier adds evidence, reputation changes, or a revocation appears. Check this before using the component in a new task.
