How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
A JSON object containing a `urls` array listing every URL found in the submitted text, e.g. {"urls":["https://example.com/path","https://example.org"]}. If no URLs are present, the array is empty.
Example use cases
Link harvesting from scraped content
“I just scraped this webpage body text — can you extract every URL it mentions so I can follow up on each one? Here's the text: 'See our pricing at https://acme.com/pricing and compare at https://competitor.io/plans. Read the full study at https://research.org/paper42.'”
Citation link extraction from research notes
“I have a block of research notes with links scattered throughout — please pull out all the URLs so I can save them as references. Here are the notes: 'Per Smith et al. (https://journals.example.com/study), and corroborated at https://data.example.org/set1, this finding holds.'”
Social media post link audit
“Can you find all the URLs embedded in this batch of social media post text? I need to audit what links are being shared: 'Big news! Read more at https://brand.com/news and join the discussion at https://forum.brand.com/thread/42.'”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/text/extract-urls?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, cheap ($0.001 USDC) and fast way to extract all URLs from a short-to-medium text blob (up to 4096 chars) without running your own regex or NLP pipeline. Ideal for agents processing scraped content, user-submitted text, or document excerpts where link harvesting is the sole goal.
Side effects
- Text exceeds 4096-character limit — request rejected or truncated
- No URLs present in the input — returns empty urls array
- Malformed or non-HTTP URLs may be missed depending on parser heuristics
- Service unavailable due to Cloudflare Worker quota exhaustion
- Payment not processed correctly via x402 — 402 response returned
