apifare for OpenAI Agents SDK

Give OpenAI Agents SDK one prepaid key for every API it needs. There is no separate provider account or provider API key for eligible capabilities, and it all runs under hard caps and a kill switch.

Get a key

1 · Get a key

Create an account at /start: email in, token out (shown once). Save the token somewhere safe.

2 · Add apifare to OpenAI Agents SDK

Connect your agent to apifare's remote MCP endpoint with MCPServerStreamableHttp. The token is read from the APIPAY_TOKEN environment variable and sent as an Authorization header.

pip install openai-agents

import asyncio
import os

from agents import Agent, Runner
from agents.mcp import MCPServerStreamableHttp

async def main() -> None:
    token = os.environ["APIPAY_TOKEN"]
    async with MCPServerStreamableHttp(
        name="apifare",
        params={
            "url": "https://apifare.com/mcp",
            "headers": {"Authorization": f"Bearer {token}"},
            "timeout": 10,
        },
    ) as server:
        agent = Agent(
            name="Assistant",
            instructions="Use the MCP tools to answer the questions.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "What's the weather in London?")
        print(result.final_output)

asyncio.run(main())

Set APIPAY_TOKEN and OPENAI_API_KEY, then run it. To run apifare locally instead, MCPServerStdio takes npx -y apifare-mcp with APIPAY_TOKEN in its env.

3 · Try it

Ask your agent to search the web for X, then to fetch a URL, then what's the weather in London. Every call is debited from your balance and lands on your signed, exportable audit chain.

4 · Stay in control

Set daily or monthly caps per agent, and keep the kill switch ready. Both are checked before a call is dispatched. When the balance runs out, your agent gets an HTTP 402 with a top-up link it can hand you; the error catalog lists every stop and what unblocks it.

What OpenAI Agents SDK can call

Everything on the key: search, filings, registries, weather, and ready-to-run tools, plus any provider key you vault yourself. Exact per-call prices are on /capabilities.
