OmniProvider

Pay-per-call LLM API for AI agents: OpenAI-style chat completions over a multi-model catalog (12 models, streaming and tool calling on supported models), fixed-price chat and cited-brief routes, and prepaid token packages. Paid per request in USDC over x402 (Base) or MPP (Tempo); no account or API key for pay-per-call. Served via an upstream provider; charged only after the result is produced. This card describes a paid HTTP API (see openapi and llms.txt); it is not an A2A task server, so call the HTTP endpoints directly.
