Bulk Create Contacts
Create several contacts in one call. Partial success is normal; read the response per record rather than assuming every row landed. Writes land in the AIsa workspace, which every caller shares: the record becomes visible and editable by others, and there is no per-caller isolation.
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. The commands per client, and what each call costs, are on aisa.one/mcp.

Cost and request rules

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): 0.012
  • Cost contract: fixed_success
  • Settlement evidence source: request_snapshot
