Machine-payable NLP micro-services: sentiment, entity extraction, summarization, report, batch. Paid per call in REAL USDC on Base mainnet.
Output
Returns a list of named entities detected in the input text, typically including the entity text span, entity type (e.g. PERSON, ORG, LOCATION, DATE), and possibly position offsets. Each call costs $0.004 USDC charged in real USDC on Base mainnet via x402.
Example use cases

Choose this endpoint when you need lightweight, pay-per-call named entity recognition without a subscription, especially in an autonomous agent context that can pay in USDC via x402. Useful for one-off or low-volume NER tasks where you want micro-payment pricing rather than a monthly API key commitment.
