tenhatch

For agents

How an AI agent finds, calls and pays for a Tenhatch tool.

Tenhatch builds every tool for machines as well as for people. Start at one index for all of them, then follow each tool’s own documents. Nothing here needs a browser.

Start at the index

Both files are generated from the same list as this site, so they never disagree with it. Each tool carries a status; links and endpoints appear when a tool is live.

tenhatch.com/llms.txt

Every tool in plain text

What each tool does, who it is for, its prices, how agents call it and its status.

tenhatch.com/.well-known/tenhatch.json

Every tool as JSON

Slug, status, kind, prices for people and for agents, the agent door and, once live, its endpoints.

What every web tool exposes

Each web tool lives on its own .com and serves the same four documents at the same paths, so an agent that has used one knows where to look on the next.

/llms.txt

A summary written for language models

What the tool does, its inputs and outputs, prices, endpoints and policies, in plain text.

/.well-known/product.json

A structured description

The same facts as JSON: the feature, its endpoint, authentication, plans and the price per result.

/api/v1/openapi.json

An OpenAPI 3.1 document

Generated from the schemas the server validates with, so the description and the API agree.

/docs/agent-access

An MCP server

The tool’s feature as MCP tools, with the same input schema as the API. Setup is on this page of each tool.

How agents pay

No seats. Agents pay for results, through an account a person sets up once, and see the price before they call.

Web tools
Authorization: Bearer <api key>
X-Usage-Source: agent

A person creates the account and the API key on the tool’s site. Calls use the plan’s monthly allowance and are billed per result after it, at the price in that tool’s llms.txt. The usage header only labels the call; it never changes the price.

Apify tools
Apify API or Apify’s MCP server

The data tools are Apify Actors. Run them from an Apify account and pay per result on Apify; the price per result is on each Actor’s Apify Store page.

Store apps
For people only

InStock First, FeedTrim, OrderColor run inside Shopify and Chrome and have no agent door.

Good manners

  • Respect Retry-After on HTTP 429. On web tools, limits are published in the X-RateLimit-* response headers.
  • Send X-Usage-Source: agent on web tools so usage is labelled as yours.
  • Read a tool’s llms.txt before calling it; prices and limits are stated there.
  • The data tools read public business data only. Do not use them to collect data about people.
