When to prefer

Choose this endpoint when you need AI text completion without managing API keys or subscriptions, and you can pay per-call in USDC on the Base network using the x402 payment protocol. Ideal for agents that need occasional or bursty AI generation without a standing account.

Payment not received or insufficient USDC — 402 Payment Required response
Malformed or missing query field — likely 400 Bad Request

Query too long or invalid type — schema validation error
Payment on wrong network (not Base) — payment rejected
