How does payment work for Content Classifier?
Each paid classification call costs $0.005 USDC on Base mainnet via the x402 v2 protocol. The payment is settled independently per request.

}Classify text or JSON input into a category using Claude AI. Supports five built-in presets and caller-supplied custom taxonomies. Returns the top label, confidence score, ranked list of all labels, and an optional one-sentence reasoning string. Args: input: Text or JSON string to classify. Max 32KB. input_type: "text" (default) or "json". When json, the string is parsed before classification. preset: Built-in taxonomy — sentiment | topic | intent | urgency | custom. sentiment: positive, neutral, negative. topic: technology, finance, health, legal, science, sports, other. intent: question, request, complaint, feedback, informational. urgency: critical, high, medium, low. custom: use your own labels via the taxonomy parameter. taxonomy: Required when preset=custom. List of 2–20 label strings. multi_label: When True, labels array contains all taxonomy labels ranked by confidence. explain: When True, include a one-sentence reasoning string. Returns: label (str), confidence (float), labels (list), reasoning (str|null), meta (dict).
Classify text into a category using Claude AI (free trial — limited presets, 4KB max). Supports sentiment and topic presets only. Multi-label is always disabled. Use classify_content for full access: all presets, custom taxonomies, 32KB input. Args: input: Text to classify. Max 4KB on trial. preset: sentiment (positive/neutral/negative) or topic (technology/finance/health/…). explain: When True, include a one-sentence reasoning string.

Content Classifier is an MCP server that classifies text or structured data into categories using Claude AI. It supports preset taxonomies (sentiment, topic, intent, urgency) or custom user-defined labels, with optional confidence scoring and multi‑label output. The server is part of the x402 micropayment task market and charges $0.005 USDC per call on Base mainnet.
The server exposes a single MCP tool classify_content via SSE transport at https://project-classifier-production.up.railway.app/sse. REST endpoints are also available: POST /v1/classify (paid, requires x402 payment header) and POST /v1/classify/trial (free, with limits). Provide parameters such as input, preset, taxonomy, multi_label, and explain to classify content.
Each paid classification call costs $0.005 USDC on Base mainnet via the x402 v2 protocol. The payment is settled independently per request.
Built‑in presets are `sentiment`, `topic`, `intent`, `urgency`, and `custom`. When using `custom`, you must provide a taxonomy array of your own labels.
Yes. The `POST /v1/classify/trial` endpoint is free but limited to 4KB input size, single‑label output only, and only the `sentiment` and `topic` presets.
The response includes a `label`, `confidence` score, optional `reasoning` string, and a ranked `labels` array when `multi_label` is true. Metadata such as the preset and model is also returned.
Yes. Set `preset` to `"custom"` and include a `taxonomy` array of your labels in the request body.
