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 a structured list of named entities found in the input text, each annotated with the entity type (e.g. PERSON, ORG, GPE, DATE) and optionally its character span or position in the source text. Deducted $0.004 USDC from the caller's wallet on Base mainnet via x402 upon successful response.
Example use cases
News article entity tagging
“Extract every person, organization, and location mentioned in this Reuters article snippet: 'President Biden met with European Commission President Ursula von der Leyen in Brussels to discuss NATO expansion and energy policy.'”
Contract party identification

Endpoint
POSThttps://9uqdtv-ip-209-115-177-214.tunnelmole.net/v1/entity-extractWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call named entity recognition without a subscription, especially in agentic pipelines that already use the x402 micropayment protocol on Base. It is part of a broader NLP toolkit on the same host (sentiment, summarization, batch), making it easy to chain with sibling endpoints. Prefer it over larger hosted NLP APIs when cost per call and crypto-native payment rails matter more than SLA guarantees.
Side effects
- Empty or missing 'text' field returns a 400 Bad Request
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Tunnelmole tunnel may be offline or unreachable, returning a connection error
- Very long texts may time out or hit payload limits
- NLP model may miss ambiguous or domain-specific entity names
