What each one is

Pinecone. Pinecone is a fully managed vector database built for AI and the knowledge platform for AI agents, providing fast, accurate retrieval that doesn't get more expensive as it scales.

TiDB Cloud. TiDB Cloud is a cloud-native distributed SQL database service that provides infrastructure for infinite agents and infinite data, with support for AI applications, vector search, and multi-modal data platforms.

Where Pinecone is ahead

Pinecone passes openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented, and TiDB Cloud does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart and official python sdk. TiDB Cloud misses those.

And on operate, machine-readable errors. TiDB Cloud misses it.

Where TiDB Cloud is ahead

TiDB Cloud passes authentication documented, and Pinecone does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail clear canonical domain, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
