Predatory pricing is selling something below cost to acquire/maintain market dominance.

The Claude subscription used for Claude Code is to all appearances being sold substantially below the cost to run it, and it certainly seems that this is being done to maintain Claude Code's market dominance and force out competitors who cannot afford to subsidize LLM inference in the same way such as OpenCode.

It's not a matter of there being a public API, I don't believe they are obligated to offer one at all, it's a matter of the Claude Subscription being priced fairly so that OpenCode (on top of, say, gemini) can be competitive.

The modern consumer benefit doctrine means predatory pricing is impossible to prosecute in 99% of cases. I’m not saying it’s right, but legally it is toothless.
