Agent Data Tools

702 pay-per-call tools for AI agents over HTTP or MCP, from $0.002 a call, most at $0.01. Free calls to start (25 over MCP, 3 over HTTP); then pay per call in USDC via x402 (Base, Polygon, Arbitrum, Solana) or by card with prepaid credits from /credits. No account needed; failed calls are never charged; per-tool reliability is public at /status. Crypto: token prices and wallet portfolios from Uniswap v3, chain reads on Base, Ethereum, Arbitrum, Optimism and Polygon, OFAC sanctions screening. Web: Read public static documentation, pages, PDFs and RSS feeds as clean text, plus link previews and sitemaps. Business: company profiles, domain and email checks. Also Bitcoin, FX, weather, holidays, geocoding, AI text, and JSON, date and validation utilities.

APIs for developers, by monthly plan or pay as you go: PDF to text API · Web page to Markdown API · Company check API · Invoice data extraction API · Document to text API

Browse all 702 tools and prices · This guide focuses on the page reader.

Read a public documentation page as clean text, Markdown, code and tables for $0.002 USDC on Base per successful call.

Static public HTML, Markdown or plain text. No JavaScript rendering, authenticated pages or paywall access. Pay with one of your free calls (add trial=1), a card key from /credits, or a funded Base wallet; an unpaid quote needs no key.

# Queue reader guide

This owned demonstration contains code, a table and ordered instructions. It is not customer data. Author/date declarations are illustrative sample data, not publication history.

## Read a job

```python
def read_job(queue):
    job = queue.pop()  # preserve two trailing spaces below
    return job  



print(read_job(queue))
```

Literal command example: `printf "a  b"` keeps two spaces inside the quoted string.

## Limits

Notation examples, not queue settings: 2^{31} and H\_{2}O.

Example configuration

## Job flow

 \[Image alt text: One job moves from the queue to a worker and returns a result.\]

Owned illustrative diagram. The reader retains source alt text, without interpreting image pixels.

## Instructions

3. Read the configuration

   - Check the limit
   - Keep code indentation
4. Process one job

sha256sum -c reader-client.mjs.sha256

shasum -a 256 -c reader-client.mjs.sha256

$line = (Get-Content -LiteralPath 'reader-client.mjs.sha256' -Raw).Trim()
$match = [regex]::Match($line, '^([a-f0-9]{64})  reader-client\.mjs$')
if (-not $match.Success) { throw 'Invalid checksum file' }
$actual = (Get-FileHash -LiteralPath 'reader-client.mjs' -Algorithm SHA256).Hash.ToLowerInvariant()
if ($actual -ne $match.Groups[1].Value) { throw 'Checksum mismatch; do not run the download' }
Write-Output 'reader-client.mjs: OK'

Need a late section? Use the optional exact section ID above. View a real section result from our long example; missing or ambiguous IDs fail uncharged. A selected result covers that scope, not the entire page.

Using a skill-capable agent? Inspect the portable reader skill and installation context. The skill grants no spending permission.

Using an MCP agent? Download the local MCP adapter for unsigned quotes and explicitly enabled, capped purchases without writing a client. Buying is disabled by default.

How paying works

Call any endpoint. Without payment it answers 402 Payment Required with a PAYMENT-REQUIRED header describing the price in USDC on Base (x402 v2, exact scheme) and a WWW-Authenticate: Payment challenge for MPP (USDC on Base or USDC.e on Tempo). An x402 client signs the payment and retries with a PAYMENT-SIGNATURE header; an MPP client (mppx) answers the challenge in Authorization: Payment. Calls that fail are not charged.

Free calls: every caller gets 25 free successful calls over MCP, used automatically before any payment, or 3 over HTTP by adding trial=1 to a GET request (failed calls do not count). Not for the AI, rendering, screenshot, transcription and search tools, nor over HTTP for PDF reading, and at most 2,000 free calls a day in total. When they run out, a card key from /credits continues the same URLs (api_key=adt_… in the URL for clients that cannot set headers). The operator can switch this off.

Payments go to 0x6293ded2684f1a76e26becef87c137d691fbf800 on Base.

Speak OpenAI already? Point an OpenAI SDK at https://tools.funwords.eu/v1: POST /v1/chat/completions, POST /v1/responses, POST /v1/embeddings, POST /v1/images/generations and POST /v1/audio/speech run the same paid tools at the same prices (Llama 4 Scout with function calling at $0.002, Llama 3.3 70B or gpt-oss-120b at $0.01 by model name, BGE-M3 embeddings at $0.01). Pay with an x402 or MPP fetch wrapper, or use a card-credit key as the SDK apiKey. GET-only clients send the same inputs in the query (/v1/chat/completions?prompt=…).

No crypto wallet? Pay by card. Buy prepaid credits ($1, $5, $20 or $100) and get an API key; send it as Authorization: Bearer adt_… on any call or on the MCP server, or as api_key=adt_… in the URL when your client can only fetch a URL. Same prices, failed calls refunded.

Advanced TypeScript client

Install with npm install @x402/fetch @x402/evm viem and npm install --save-dev typescript tsx @types/node. Save this as client.ts and run npx tsx client.ts. It reads the private key only from the environment, pins Base, this service's recipient and Base USDC, and caps spend at the /extract price. It does not request a free trial. Most tools cost $0.01; a few cost up to $0.04, so raise the cap to call those.

// Save as client.ts; set X402_PRIVATE_KEY in your environment, never in source.
import { ExactEvmScheme } from "@x402/evm";
import { wrapFetchWithPayment, x402Client } from "@x402/fetch";
import { privateKeyToAccount } from "viem/accounts";

const rawPrivateKey = process.env.X402_PRIVATE_KEY;
if (!rawPrivateKey || !/^0x[0-9a-fA-F]{64}$/.test(rawPrivateKey)) {
  throw new Error("Set X402_PRIVATE_KEY in a secret manager or process environment.");
}
const account = privateKeyToAccount(rawPrivateKey as `0x${string}`);
const serviceOrigin = "https://tools.funwords.eu";
const expectedPayTo = "0x6293ded2684f1a76e26becef87c137d691fbf800";
const baseUsdc = "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913";
const maxUsdcAtomic = 10000n; // $0.01 USDC, the ordinary per-call price (/extract costs $0.002)

const client = new x402Client()
  .register("eip155:8453", new ExactEvmScheme(account))
  .setSpendControls({ maxAmountPerPayment: "$0.01" })
  .registerPolicy((_version, requirements) =>
    requirements.filter((requirement) => {
      if (requirement.network !== "eip155:8453" || requirement.scheme !== "exact") return false;
      if (requirement.payTo.toLowerCase() !== expectedPayTo) return false;
      if (requirement.asset.toLowerCase() !== baseUsdc.toLowerCase()) return false;
      return /^\d+$/.test(requirement.amount) && BigInt(requirement.amount) <= maxUsdcAtomic;
    }),
  );

const fetchWithPayment = wrapFetchWithPayment(fetch, client);
const response = await fetchWithPayment(new URL("/extract?url=https%3A%2F%2Fexample.com", serviceOrigin));
if (!response.ok) throw new Error(`API returned HTTP ${response.status}`);
console.log(await response.json());
