How this service works
Pay-per-call API for AI agents, settled in USDC on Base mainnet (eip155:8453) via the x402 protocol - no API keys, no signup, no subscription. Live crypto market data: BTC, ETH, SOL, USDC (USD Coin) prices with 24h change (source: OKX), Base mainnet chain snapshot (block height, gas price gwei), real-time USDC-on-Base transfer analytics (transfer count, volume, unique senders and recipients over recent blocks), and USDC/ETH wallet balances plus nonce for any address. Agent utility tools: deterministic JSON repair for LLM output (strip code fences, fix trailing commas, single quotes, unquoted keys, balance braces), DNS A/AAAA lookup, and URL extraction from arbitrary text. Every endpoint returns HTTP 402 with an x402 payment challenge in USDC on Base; pay with any wallet and retry with the PAYMENT-SIGNATURE header. MCP server at /mcp (streamable HTTP, 6 pay-per-call tools). Ideal for crypto portfolios, DeFi dashboards, market analysis agents, data pipelines, and LLM post-processing.
Output
Returns a JSON object containing a list of all URLs found in the provided text, including full HTTP/HTTPS addresses and any other URL patterns detected in the input string.
Example use cases
Extract links from LLM output
“I got a response from an AI that mentions several websites but they're buried in a paragraph — can you extract all the URLs from this text: 'Visit our homepage at https://mysite.com, check the tutorial at https://learn.mysite.com/start, and the API reference at https://api.mysite.com/docs'?”
Parse URLs from scraped article
“Here's a raw block of scraped article text that mentions a bunch of links — can you extract every URL you find in it? The text is: 'According to Reuters (https://reuters.com/article/123) and Bloomberg (https://bloomberg.com/news/456), the market rose today. More at https://finance.yahoo.com.'”
Find links in user-submitted content
“A user submitted this comment and I need to know if it contains any URLs for moderation — can you extract all links from: 'You should really visit http://suspicioussite.biz and also check out https://anotherlink.net/promo for great deals!'”
Technical details
Endpoint
GEThttps://baseusdcearn.pythonanywhere.com/text/extract-urls?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call URL extraction utility with no API key or signup required, especially within a workflow already using the x402/USDC payment protocol on Base mainnet. Ideal for pipelines processing LLM output or raw text that may contain embedded URLs needing further retrieval or validation.
Side effects
- No text provided — returns empty URL list or error
- Text contains no recognizable URLs — returns empty array
- HTTP 402 returned if x402 payment challenge not fulfilled — requires USDC payment on Base mainnet and retry with PAYMENT-SIGNATURE header
- Malformed or very long input text may cause parsing errors
