AgentBeacon vs Coresignal for AI agents

Coresignal is a B2B jobs data API and dataset of deduplicated job postings merged from many sources into one format. 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

  • Coresignal: Large-scale, historical job-postings data for analytics, research and data products.
  • 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.

Acting on a resultexternal_url is the job URL on the company's own site (not always filled); job_sources[].url gives each source posting.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 resultsNot stated on its pagesAgents read beacons and message them; the terms say reading one doesn’t give the right to reuse it freely.
AI in its termsNot stated on its pagesBuilt 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=remote analytics engineer jobs over 130k"

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("remote analytics engineer jobs over 130k"));

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