BitBooth Agent Tools MCP server

BitBooth

BitBooth's featured product is PageDelta, a paid page observation API for agents.

POST https://app.heinrichstech.com/v1/cdp/render-pro
$0.01 per observation

A buyer does not need a BitBooth account or subscription. Send a page URL, inspect the x402 challenge, pay with a supported stablecoin rail, and receive rendered Markdown plus bounded change evidence.

What PageDelta does

The first paid observation saves a baseline scoped to the payer, canonical URL, and extraction mode. A later paid observation of the same scope compares the new result with that saved baseline.

Each successful response can include:

• rendered, bounded Markdown
• an exact, case-sensitive focus search result
• a structured, bounded line diff
• the prior baseline status and saved revision
• a new opaque cursor for continuity checks
• content and observation hashes
• an optional bounded JPEG snapshot
• settled payment metadata and a PAYMENT-RESPONSE receipt

The cursor is not an access token, and returned web content is untrusted input. Agents should still apply their own prompt-injection and data-handling policy.

Inspect the live challenge

This request does not pay. It returns HTTP 402 with the current payment requirements in the PAYMENT-REQUIRED header.

curl -i -X POST https://app.heinrichstech.com/v1/cdp/render-pro \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com","extract":"article","focus":"Example Domain"}'

For production PageDelta, the advertised rails are:

The fresh 402 challenge is authoritative for the exact network identifier, asset or issuer, amount, recipient, and timeout. PageDelta does not advertise a Solana rail.

Try the complete flow without real money

Open the PageDelta browser demo. It runs an isolated XRPL Testnet exercise:

1. The tab creates a temporary wallet in browser memory.
2. The official faucet funds it with valueless test XRP.
3. The first observation pays 1,000 test drops and saves a payer-scoped baseline.
4. The demo changes its isolated page from revision 1 to revision 2.
5. The second observation pays another 1,000 test drops and returns the change.
6. The run ends with two XRPL Testnet receipts.

Confirmation retries reuse the same signed proof. They do not create additional payments. This demo proves the test flow only. It is not a production payment and does not represent revenue.

Use the MCP buyer

The current buyer is @bitbooth/mcp-fetch@2.3.1. Its official MCP registry name is io.github.Drock91/bitbooth-fetch.

For free catalog discovery, no wallet credential is required:

{
  "mcpServers": {
    "bitbooth": {
      "command": "npx",
      "args": ["-y", "@bitbooth/mcp-fetch@2.3.1"]
    }
  }
}

The packaged PageDelta buyer currently automates the XRPL mainnet RLUSD path. Enabling it requires an explicit xrpl-rlusd rail, a dedicated low-balance XRPL wallet, and a per-call limit of at least 0.010000. See the integration guide before adding a seed.

Discovery scope

https://app.heinrichstech.com/bazaar.json currently features exactly one resource: PageDelta at /v1/cdp/render-pro.

That featured catalog is a deliberate release surface. It is not a count of everything implemented inside BitBooth. Internal and reference routes may exist outside it, and private seller routes are not automatically published there.
