How this service works
Extract numbers from free text. Call when scraping prices, IDs, quantities, or scores out of messy agent-collected text. Returns the ordered list of numbers found—no LLM, no regex maintainance on your side. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
An ordered JSON list of numbers found in the submitted text, in the sequence they appear — no LLM interpretation, no regex setup required, just the raw numeric values extracted deterministically.
Example use cases
Scraping prices from e-commerce text
“Here's a messy product description I scraped: 'Was $49.99, now only $34.50 — save 31%! Only 8 left in stock.' Can you extract all the numbers from it?”
Pulling IDs from API response text
“I got this raw text back from an API and need all the numeric IDs out of it: 'Order ref 100234 linked to customer 8871 with invoice 56032.' Extract all the numbers.”
Parsing scores from review summaries
“Take this review summary and pull out every number you find: 'Rated 4.2 stars from 1,340 users; 87% recommend, average wait time 12 minutes, price score 3 out of 5.'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/extract-numbersWhen to prefer
Choose this endpoint when your agent needs to reliably pull numeric values (prices, IDs, quantities, scores) from messy or unstructured text without maintaining custom regex patterns or invoking an LLM. It is deterministic, requires no API key or subscription, costs $0.001 USDC per successful call via x402 on Base, and only charges on success — making it ideal for high-frequency agentic pipelines where predictability and low cost matter.
Side effects
- Text exceeds 100,000 character limit — returns a structured validation error (not billed)
- No numbers found in text — returns an empty list
- Malformed request body — returns a structured validation error (not billed)
- Payment not attached or insufficient — returns 402 payment required
