How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
A JSON object containing extracted named entities from the input text, including entity labels (e.g. PERSON, ORG, GPE) and their surface forms or spans within the text.
Example use cases
Entity extraction for knowledge graph
“I have this news article text and I need to extract all the people, organizations, and locations mentioned so I can build a knowledge graph — can you run NER on it?”
Compliance document screening
“Scan this contract text and pull out every company name, person, and jurisdiction mentioned so I can flag any restricted entities.”
Research paper entity tagging
“Extract all named entities from this abstract: 'OpenAI and Microsoft partnered to deploy GPT-4 in Azure datacenters across Europe and Southeast Asia.'”
Technical details
Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/text/entities?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call named entity recognition on arbitrary text without setting up your own NLP infrastructure. Ideal for agents that encounter documents or web content at runtime and need to extract structured entity data on demand. Particularly useful in x402-native pipelines where per-call micropayments in USDC are already the payment model.
Side effects
- Text exceeds 500,000 character limit — request rejected
- Malformed JSON body or missing required 'text' field — 400 error
- Payment not attached or insufficient USDC — 402 payment required
- Empty text input returns empty entity list
- Non-English or low-resource language text may produce poor extraction quality
