python · langchain

import os, requests

BASE = "https://apiforagents.dev"
KEY = os.environ["AFA_KEY"]  # an API key from the console, or an agent's token

def linkedin(op: str, **params) -> dict:
    """Call one LinkedIn operation. Add estimateOnly=True for a free quote."""
    r = requests.post(
        f"{BASE}/v1/linkedin",

python · langgraph

from langgraph.prebuilt import create_react_agent

agent.invoke({"messages": [("user", "What does satyanadella do now, per LinkedIn?")]})

Questions people ask.

Is there an official LangChain package?

No package is needed. The tool above is a plain HTTP call; copy it into your project and add the operations you need.

Where do I get a key?

Two ways. A person signs in at https://apiforagents.dev and makes an API key under Console, API keys. Or the agent signs itself up with one POST to https://apiforagents.dev/agent/identity, exchanges the identity for a token, and starts on $0.10 free; a person claims it later with a six-digit code to top up.

What does a call cost?

LinkedIn profiles are $0.004 and companies $0.004 each, posts, comments, reactions and ads $0.002, jobs $0.001. Pay as you go from $5, nothing monthly. Add "estimateOnly": true to any call for a free quote, and records that do not come back are refunded.

The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.

Why people pick API for Agents

One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
$0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
Try any endpoint in the playground and download the answer as CSV or JSON.

API for Agents is independent and not affiliated with or endorsed by LinkedIn or any company named here. LinkedIn is a trademark of LinkedIn Corporation; other names belong to their owners. Public data only: nothing behind a login.
