Agent services, priced per call.

Ten HTTP endpoints your agent can call and pay for in the same request. Payment is USDC over the x402 protocol on Base (or MPP), so there's no account, no API key and nothing to invoice. Every call runs on Agent Harbor's own hardware.

How payment works.

Your agent pays inside the HTTP exchange itself. Any x402 client library handles the steps below for you.

  1. Call the endpoint without paying. You get 402 Payment Required, with the x402 v2 terms base64-encoded in the PAYMENT-REQUIRED header.
  2. Sign a USDC payment for the quoted amount. Scheme exact, on Base, to the address in the terms.
  3. Retry with the payload in PAYMENT-SIGNATURE. We produce the result first, then settle. Nothing is charged unless the call is served.

Endpoints priced $0.01 and up also accept the Machine Payments Protocol: the 402 carries a WWW-Authenticate: Payment challenge, paid in Tempo USDC and settled through Stripe.

Prices are per call in USDC. Response targets are the longest a call should take; most return sooner. The live /catalog is the source of truth if anything here differs.

Questions from agent builders.

Do I need an account or an API key?

No. Payment is the authorization. Any caller with a funded wallet and an x402 client can use every paid endpoint.

What does my agent need to pay?

A wallet holding USDC on Base mainnet and an x402 v2 client that can sign an exact payment. Agents set up for the Machine Payments Protocol can pay the $0.01-and-up routes with Tempo USDC instead. There's no minimum balance and nothing to top up with us.

Am I charged if a call fails?

No. We produce the result before the payment settles, and nothing is charged unless the call is served.

Where does my input go?

To our machines in Bremerton, Washington. Models run on our own hardware, so what you send isn't passed to a third-party AI provider. Public-records endpoints read the public source they name, such as SEC EDGAR.

How do I know a result is trustworthy?

Our scrape and enrichment responses carry a validation block: each platform claim is scored against the page evidence behind it, unsupported claims are struck with a reason, and the response names the model, time and gate version that checked it.

What about prompt injection in scraped pages?

/scrape, /enrich and /company include a free content_safety field that flags injection patterns in the site text we return, with the JSON path, the rule that matched and an excerpt.

Can a person use these without writing an agent?

Yes. Any x402 client works from a script, and the site audit is also available on the Apify Store with no crypto wallet needed.

I need data you don't sell yet.

Email anchor@agentharbor.agency with what your agent needs and what it would pay per call. New endpoints come from requests like that.

Building something on top of us?

We'd like to hear about it, especially if you need higher volume or a new endpoint.
