POST
Manage List Entries
Adds one address or domain to an account-wide allow or block list and returns the created entry. 🔴 This is a standing rule that changes mail handling for every inbox in the account, including other callers’ — the inbox-scoped post_agentmail_inbox_list_entry affects only one inbox and is almost always the one you want. Every AIsa caller shares one AgentMail account, so this reaches inboxes other callers created.

Example

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 a few meta tools: search, list_categories, get_details and batch_quote are free, batch_use is 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

Published reference price: $0.012 USD per successful request. 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): 0.012
  • Cost contract: explicit_zero
  • Settlement evidence source: request_snapshot
