Inspect every `*Truncated` flag before treating a returned array as complete. ## OpenAPI ````yaml /api-reference/retardmarket_openapi.yml get /markets/{marketId}/activity openapi: 3.0.3 info: title: retard.market API version: 12.27.0 description: | Attested Robinhood Chain reads for the experimental memecoin launch, trading, and staking protocol behind `/retard`. Each market is built around a fixed-supply creator memecoin paired with native ETH in a Uniswap v4 pool. The API exposes runtime identity, markets, quotes, activity, wallet holdings and positions, and funded creator-tip proofs. This protocol is experimental. Contracts, economics, API responses, and availability may change, and funds may be lost. Verify the runtime contract graph and simulate every wallet transaction immediately before signing. Use is subject to the VibeChain Terms of Service at https://vibechain.com/terms. Every endpoint requires a caller-specific VibeChain API key in the `API-KEY` header.
