Give AI agents Twitter/X access without $5k API keys. 248 MCP tools, BYOA credentials, pay-per-call x402 — USDC on Base, USDT on X Layer.
xbird is a Twitter/X API for AI agents.
Agents get 248 MCP tools (search, read, post, engage, DMs, lists, media) via CLI, MCP (Cursor/Claude), and a pay-per-call REST API. Auth is BYOA: users bring their own X credentials — xbird does not resell the official X developer API.
Payments use x402 micropayments: USDC on Base and USDT on X Layer (OKX.AI dual-rail). Live A2MCP ASP on OKX.AI marketplace (#3460).
