HALOWERK

Services for Agents

HALOWERK provides endpoints an AI pays for on its own, per request. No account, no signup, no API key. One call, one price, one answer.

The problem

An agent with a task to finish rarely fails at reasoning. It fails because the data sits behind a signup. Create an account, request a key, add a billing address — a machine cannot do that, and for a single call it would not be worth it anyway.

HALOWERK turns that around. Every service states its price in the response, the agent pays within the same exchange, and receives the result. The whole thing takes milliseconds and usually costs a fraction of a cent.

How a call works

  1. The agent asks.An ordinary POST to the endpoint, with no credentials.
  2. The service answers 402.It carries the price, chain, asset, recipient and the expected input schema. All machine readable.
  3. The agent pays and asks again.Payment runs over x402 on Base, in canonical USDC.
  4. The service delivers.Settlement happens only after a valid answer exists. If the work fails, nothing is charged.

What HALOWERK covers

Web and data

Read, check, structure

Turn pages into clean data, detect structure, repair broken formats, redact personal information.

Verification

Before it gets expensive

Addresses, phone numbers, bank details, company records and sanctions lists. Customs classification against the official EU nomenclature.

Onchain

See what happens

Contracts, authorities, holder distribution, allowances. Simulate a transaction before it is signed.

Market

Numbers with an age

Prices, order books, liquidity and slippage. Every number carries its source and its age in milliseconds.

What we hold ourselves to

No invented values

Anything that cannot be evidenced comes back as null and is listed separately. Gaps are reported, not smoothed over. An estimate is labelled as an estimate, together with the method used.

Evidence, not assertion

Every derived number names its source, its window and its age. Where a judgement is formed, the thresholds used are stated in the response. No black box.

Read only

No service signs, broadcasts or executes. Simulations run against a fork. No private key sits in any service.

No advice

HALOWERK delivers numbers and assessments. Not trading signals, not price targets, not investment advice, not legal counsel.

What a 402 offer looks like

POST https://api.halowerk.com/… → 402 Payment Required

{
  "x402Version": 2,
  "accepts": [{
    "scheme":  "exact",
    "network": "eip155:8453",
    "asset":   "USDC",
    "maxAmountRequired": "…",
    "payTo":   "0x…",
    "maxTimeoutSeconds": 60
  }],
  "resource": {
    "description": "…",
    "inputSchema": { … },
    "mimeType": "application/json"
  }
}

Description and input schema travel inside the offer. An agent knows what it is paying for, and what to send, before it pays.

Status HALOWERK is being built. The catalogue keeps growing, and each service address is published here once it is reachable. The machine readable version lives at /llms.txt.
