AgentBeacon vs Foursquare Places API for AI agents

Foursquare Places API is Foursquare's pay-as-you-go API for searching and reading point-of-interest data from its global places database. AgentBeacon is built on beacons, each a few plain words about what someone has or needs right now, live while they renew it. Each result is one, with the employer’s Apply link for a hiring beacon or an address to message a business’s through AgentBeacon. It needs no key.

The short answer

  • Foursquare Places API: A low-cost global POI API with phone, website and email at the cheaper Pro tier. Good for place lookup and matching where Google-style display rules are too tight.
  • AgentBeacon: Giving an agent a job to apply for or a home-service business to message, with no key.

AgentBeacon covers far less today: jobs in Austin, Texas, and remote, and businesses in and around Austin. Where it has what the agent is looking for, it is free and needs no sign-up.

PaidPro endpoints: $15.00 per 1,000 calls (501 to 100,000), falling to $9.00 at volume. Premium endpoints: $18.75 per 1,000 (up to 100,000). Ask endpoints: $30 (Pro) or $36 (Premium) per 1,000.Free for agents
Acting on a resultPhone (tel), website and email are Pro fields. There is no way to message a business through the API.A hiring beacon has the employer’s Apply link; every other beacon is messaged through AgentBeacon, and the business replies there. A business that hasn’t taken over the beacon AgentBeacon seeded for it isn’t told, so a message to it waits 30 days.
Limits on keeping or showing resultsThe Developer Master Terms forbid creating derivative works of the service or its underlying data. They also treat place data as Foursquare Confidential Information, even where the facts are public. No specific cache period was found.Agents read beacons and message them; the terms say reading one doesn’t give the right to reuse it freely.
AI in its termsThe terms forbid accessing the service "to develop or improve any point-of-interest or venue dataset, algorithm, or machine learning operation(s)." The product page markets the API for AI agents through MCP.Built for AI agents. An agent may act only with its owner’s permission, and the terms don’t let AgentBeacon train AI models on what businesses write.

Try AgentBeacon

Connect, then find:

curl https://api.agentbeacon.sh/v1/connect \
  -H 'Content-Type: application/json' \
  --data-binary '{}'
curl -G https://api.agentbeacon.sh/v1/beacons \
  -H "Authorization: Bearer $AGENTBEACON_TOKEN" \
  --data-urlencode "q=plumber near Austin, TX"

Or let the JavaScript client connect for you. The Python client, agentbeacon-sdk, works the same way.

npm install @agentbeacon/sdk

import { find } from "@agentbeacon/sdk";
console.log(await find("plumber near Austin, TX"));

Agent apps that take MCP servers can add https://api.agentbeacon.sh/mcp/search, which needs no sign-in. The local businesses docs have the full code, every parameter and each line of the answer.
