LlamaIndex Tools Integration: AnyAPI

AnyAPI is one key and one USD wallet in front of hundreds of data and scraping APIs: Reddit, Instagram, TikTok, YouTube, LinkedIn, Google search and maps, Amazon, and clean JSON from pages that block bots. There is no subscription; you are billed per request in USD.

This package exposes AnyAPI to LlamaIndex as a single AnyAPIToolSpec.

Install

pip install llama-index-tools-anyapi

Set ANYAPI_API_KEY, or pass api_key= to the tool spec. Get a key at getanyapi.com.

Usage

from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI
from llama_index.tools.anyapi import AnyAPIToolSpec

agent = FunctionAgent(
    tools=AnyAPIToolSpec().to_tool_list(),
    llm=OpenAI(model="gpt-4.1"),
)

print(await agent.run("What is trending on Reddit right now?"))

The tools also work on their own:

spec = AnyAPIToolSpec()
spec.search_apis("trending posts on reddit", limit=3)
spec.get_api("reddit.trending_posts")  # read the strict input schema
spec.run_api("reddit.trending_posts", {"limit": 2})

Every tool has an awaitable twin (asearch_apis, aget_api, arun_api, and so on) backed by AsyncAnyAPI, so await tool.acall(...) talks to AnyAPI asynchronously rather than running the blocking client on a thread.

A runnable script is in examples/basic_usage.py.

The five tools

AnyAPI publishes hundreds of SKUs. One tool per SKU would exhaust any agent's context, so this spec ships the AnyAPI MCP server's discovery-then-run loop instead.

Search and browse results carry no input schema. Call get_api for an API before your first run_api on it and build the input from the schema it returns: every input schema is strict, so an invented field name fails the call.

Prices

Every static price is published in both denominations and neither is derived from the other. maxUsd is what one request is billed; maxPer1kUsd is the same price per 1,000 requests. Quote the per-1k figure to a person, and never multiply a price yourself. A per-call charge comes back as costUsd on the run result.

There is no quote tool. get_api already publishes pricing.from.maxUsd, the most a first-choice run is billed, and pricing.failoverMaxUsd, the ceiling for any run of that API, so an agent can bound its spend before calling.

Departures from the AnyAPI MCP server

The tool descriptions are the MCP server's own wording, because it already encodes what agents get wrong. Four things differ here:

• there is no quote tool, for the reason above;
• search results carry no heavy marker;
• search requires a query;
• the MCP server names its tools anyapi_search_apis, anyapi_get_api and so on, and the shared wording is written that way. Here the tool spec is the namespace, so the tools are search_apis, list_apis, get_api, run_api and get_balance, and the anyapi_ prefix is stripped from the descriptions when they are bound, so every tool a description names is one you can call.
