Services AI agents call, and pay for, on their own.

Agent Harbor runs ten pay-per-call endpoints for company data, site audits, public records and developer tools. Any agent can call one and settle in USDC over x402: no account, no API key, no monthly bill. Everything runs on our own hardware in Bremerton, Washington.

One request, one payment, one answer.

There's nothing to sign up for. An agent asks, we quote a price in the response, the agent pays in USDC, and the data comes back on the retry.

  1. The agent calls an endpoint. A plain HTTP request, such as GET /company?domain=…
  2. We answer 402 Payment Required. The price, network and pay-to address ride in the PAYMENT-REQUIRED header.
  3. The agent signs a USDC payment and retries. The signed payload goes in the PAYMENT-SIGNATURE header.
  4. We return the data. Payment settles on Base, straight to Agent Harbor. Nothing is charged unless the call is served.

Prefer the Machine Payments Protocol? Endpoints priced $0.01 and up also accept MPP, paid in Tempo USDC and settled through Stripe.

Every way in leads to the same harbor.

Agents find us through discovery listings and pay us through the gateway or the Apify Store. Whichever door they use, the work runs on the same machines and the money comes to Agent Harbor.

How callers reach Agent Harbor AI agents, agent platforms, Apify users and developers reach Agent Harbor through the x402 gateway, the x402 Bazaar listing, the Apify Store, and the agent card and llms.txt discovery files.

Where agents find us.

We list our services wherever buying agents already look, and publish the files that let any agent work out what we sell without a human in the loop.

  • MCP server

Our own machines, and receipts for every claim.

We don't resell another company's model. Paid calls run on hardware we own, and our data endpoints show their work.

  • Private inference. Models run on our own machines. What an agent sends us isn't passed to a third-party AI provider.
  • Separated by design. One machine faces the internet; the inference machine has no public address at all.
  • Claims checked against evidence. Scrape and enrichment responses score each platform claim against the page it came from, and strike the ones that don't hold up, with a reason.
  • Prompt-injection flags, free. /scrape, /enrich and /company mark injection patterns in the site text they return, with the rule and an excerpt, so your agent can quarantine them.
  • Provenance on every response. Each result names the model, the time and the version of the gate that checked it.

A company run by its own agents, steered by a person.

Agent Harbor uses what it sells. A crew of agents on local and open models does the day-to-day work, around the clock, and the founder signs off on anything that matters.

Research and product scouting

Agents study what paying agents buy and propose the next endpoint to build.

Code, tests and review

Changes arrive as reviewed pull requests with tests, and every deploy is logged.

Books and reporting

Revenue, payments and tax reserves are tracked daily and summarized in a morning brief.

A human with the final say

Spending money, publishing a listing, or widening an agent's permissions always waits for the founder's approval.

For businesses: an agent fleet we build and run for you.

The same infrastructure powers managed agent fleets for small and mid-size businesses: a named primary agent plus single-function subagents for intake, follow-up, research and reporting. We design, deploy and run it on our hardware; you get the results.
