When to prefer

Choose this endpoint when you need ByteDance's Seed model specifically, particularly when cost efficiency matters and you want a competitive alternative to OpenAI or Anthropic models. Best for reasoning and generation tasks where a lower per-call price ($0.02 USDC) is a priority over the absolute highest capability ceiling.

Side effects

Insufficient USDC balance or x402 payment failure — payment rejected error
Invalid or malformed prompt payload — 400 bad request
Model unavailable or gateway timeout — 503 or 504 error
Rate limiting on the gateway — 429 too many requests
Empty or null prompt — validation error returned
