How this service works
Machine-payable NLP micro-services: sentiment, entity extraction, summarization, report, batch. Paid per call in REAL USDC on Base mainnet.
Output
Returns NLP analysis results for all submitted texts in the batch, which may include sentiment labels and scores, extracted named entities, text summaries, and/or a structured report — depending on what the batch endpoint processes. Response is delivered after the x402 micropayment of $0.02 USDC on Base mainnet is confirmed.
Example use cases
Batch review sentiment for e-commerce
“Analyze the sentiment of these 10 product reviews all at once and tell me which are positive, negative, or mixed: ['Loved it!', 'Broke after a week.', 'Good value for money.', 'Worst purchase ever.', 'Decent but not great.', 'Exceeded my expectations!', 'Arrived damaged.', 'Pretty good overall.', 'Not worth the price.', 'Absolutely fantastic!']. Pay the USDC fee automatically.”
Entity extraction across news snippets
“Pull out all named entities — people, companies, and locations — from these five news headlines in one batch call: ['Elon Musk visits Berlin factory', 'Apple launches new chip in Cupertino', 'Amazon acquires startup in Seattle', 'Google faces EU antitrust probe', 'Meta opens AI lab in London']. Use the x402 batch endpoint and cover the micropayment.”
Multi-document summarization for research
“Summarize each of these three research abstracts into a single sentence each, using the batch NLP endpoint: ['Abstract 1 text here...', 'Abstract 2 text here...', 'Abstract 3 text here...']. Handle the $0.02 USDC payment on Base and return the summaries.”
Technical details
Endpoint
POSThttps://rqjzcd-ip-209-115-177-214.tunnelmole.net/v1/batchWhen to prefer
Choose this endpoint when you need to process multiple texts through NLP operations (sentiment, entity extraction, summarization) in a single API call and can pay $0.02 USDC per call on Base mainnet via the x402 protocol. Prefer this over single-text endpoints when you have multiple documents to analyze and want to minimize round-trips. Best suited for autonomous AI agents with a USDC wallet that need machine-payable NLP without OAuth or API key management.
Side effects
- Payment failure: insufficient USDC balance or misconfigured wallet returns 402 Payment Required
- Invalid input: missing or malformed 'text' field returns 400 Bad Request
- Tunnel/proxy downtime: tunnelmole relay is offline, returns 502 or connection timeout
- Rate limiting: too many rapid calls may be throttled
- Empty batch: submitting an empty text array may return an error or empty results
