AI API Router Directory

Perplexity's API blends request and token pricing: Search API at $5 per 1,000 requests; Sonar at $1/$1 tokens plus a $5–$12 per-1K request fee that scales with search depth; and the new Agent API serving OpenAI, Anthropic, Google and xAI models at direct provider rates with no markup, plus per-invocation tool pricing (web_search $0.0025). Sonar is sunset after September 27, 2026 — the Agent API is the successor.

No free tier on the API (checked 2026-09-16). Consumer Pro/Max plan credits (35K bonus + 10K monthly) apply to the app, not the API.

RenAI (renai.uno) is an OpenAI-compatible AI API gateway that aggregates multiple global and Chinese models, including OpenAI, Anthropic, Google, and DeepSeek. It operates on a balance top-up model and is designed for users needing high-compatibility access to a broad range of upstreams.

SAP generative AI hub is model management and orchestration for enterprise AI inside SAP AI Core, giving developers one API across hosted SAP models and partner models such as Anthropic Claude Sonnet 4, Google Gemini 2.5 Pro and OpenAI GPT-5, with prompt lifecycle management, an experimentation playground, automated prompt optimisation and inference observability. SAP does not publish list prices for it: the official trial page states the 30-day basic trial, after which the service is bought through Pay-As-You-Go for SAP BTP or an Enterprise Agreement, with pricing details routed to the SAP Discovery Center service catalogue. A page footnote states that token and after-promotion optimisation costs apply.

SAP offers a 30-day basic trial of generative AI hub with no dollar credit value stated on the official trial or product pages; it is a time-boxed licence grant, not a cash allowance (checked 2026-09-16).

SEA-LION (Southeast Asian Languages In One Network) is a suite of LLMs specifically optimized for Southeast Asian languages and cultural contexts. The API platform allows developers to integrate these regional models into localized applications with easy Google-auth signup.
