Word Counter API

Count words, characters, sentences, paragraphs, reading time. x402 micropayment.

Overview

AI-generated overview

Remote MCP endpoint that counts words, characters, sentences and paragraphs in text and estimates reading time, billed per call via x402 micropayments.

What you can do
  • Count words, characters, sentences and paragraphs in a piece of text
  • Estimate reading time from the returned statistics
  • Return a combined statistics response (words, characters with and without spaces, sentences, paragraphs, reading time)
When to use it
Useful when an assistant needs quick text-length metrics, such as validating content against minimum word counts or estimating how long an article takes to read before publishing. It is a narrow single-purpose service, so it only makes sense if you want that check as a paid remote call.
Requirements
A remote MCP client pointed at the hosted endpoint; nothing to install locally. No API key or signup, but each call is paid in USDC on the Base L2 network through the x402 protocol, so an x402-capable client and a funded wallet are needed. Network access to the provider's domain is required.
Before you install
Every call costs money (listed at $0.003 per count) and is settled in USDC on Base, so an assistant with wallet access can spend funds without further confirmation. The text you submit is sent to a third-party hosted service. Payment is handled through Coinbase CDP and PayAI facilitators, and the service is part of a larger commercial API marketplace.

Installation

In SourceWeft

  1. Open Word Counter API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fword-counter/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Word Counter API

[MCP Server] [x402] [License: MIT]

Analyze text metrics: word count, characters, sentences, paragraphs, and estimated reading time in one call. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "word-counter": {      "url": "https://word-counter.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://word-counter.api.klymax402.com/api/count" \  -H "Content-Type: application/json" \  -d '{"text":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
