Reference example
Ask a question and get an answer that an OpenAI model wrote after searching the live web. Send a Responses request — an input string (or message array) — and the endpoint injects a fixed, server-pinned model and the web_search tool for you; the model, tool and per-request search cap are server-controlled to keep cost bounded. The reply is a standard OpenAI Responses object: output[] contains web_search_call items (each a search that ran) and a message item with the answer text and URL citations, and the billed search count equals the number of web_search_call items. Billing is pay-as-you-go: a per-search charge for each of web_search_calls plus the model’s own token cost (fresh input = input_tokens − cached). Use this when you want a written, cited answer grounded in current web content from an OpenAI model — for the Anthropic-model equivalent see post_anthropic_websearch_search, and for raw ranked links with extracted page text use post_tavily_search.
First time? Point any MCP client at https://mcp.aisa.one/mcp — Claude Code, Codex, Cursor, VS Code and the rest. Authorization is OAuth: the client opens a browser, you click Allow once, and there is no key to paste. Your agent then reaches every endpoint through five tools: search, list_categories and get_details are free, use and batch_use are billed per call. Setup per client is in Connect via MCP; the live tool list and what each call costs are on aisa.one/mcp.

Request contract

Complete OpenAPI definition Effective request and pricing declaration (including authentication and referenced schemas):

Cost and request rules

Usage-based billing; Default request estimate: $0.3 USD (not a fixed price). Account-specific pricing and final settlement may differ. Published reference values are not an account-specific quote or a settled charge. For endpoints supporting X-AISA-Cost-Mode: quote, obtain a free quote for your exact request before execution; reconcile the settled cost with response metadata and Usage Logs. USD amounts use 1,000,000 integer micro-USD per dollar.
  • Default request reference estimate (USD): 0.3
  • Cost contract: response_components
  • Published reference multiplier: 1.0
  • Settlement evidence source: response_body
