How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the numbers extracted from the input text, likely as an array of numeric values or annotated numeric entities found within the provided string.
Example use cases
Financial figure extraction from reports
“Here's a paragraph from an earnings report — pull out every number and figure in it: 'Net income rose to $2.8 billion, a 23% increase, on revenue of $14.1 billion across 48 markets with 72,000 full-time employees.'”
Data mining from news articles
“I have this news article snippet and I need all the numeric values extracted from it: 'The storm caused 340 flight cancellations, affected 1.2 million passengers, and caused an estimated $500 million in damages over 3 days.'”
Parsing statistics from research text
“Extract every number from this research summary: 'Participants scored an average of 78.4 points, with a standard deviation of 6.2. The study ran for 90 days across 5 sites with a total of 1,200 subjects aged between 18 and 65.'”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/text-extract/numbers/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, cheap ($0.0005 USDC), pay-per-call solution to extract numeric values from unstructured text without standing up your own NLP pipeline. Ideal for agents processing financial documents, news articles, or research summaries at scale where cost efficiency matters. Best when the input text is under 50,000 characters and you need raw number extraction rather than semantic understanding of what those numbers mean.
Side effects
- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text input returns empty result set
- Payment failure via x402 if USDC balance is insufficient
- Ambiguous numeric formats (e.g. dates vs integers) may be inconsistently extracted
- Non-standard number representations (Roman numerals, written-out words) may not be captured
