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 'hashtags' array of strings, each representing one hashtag token found in the input text (e.g. {"hashtags": ["Lisboa", "AI"]}). Hashtag symbols (#) are typically stripped, leaving only the keyword portion.
Example use cases
Hashtag audit for social post
“I'm about to publish this Instagram caption — can you pull out all the hashtags so I can review them before posting? Caption: 'Big day in #NewYork! Excited for #TechSummit2025 and all things #AI and #innovation.'”
Topic tagging for content pipeline
“We're ingesting user tweets into our analytics dashboard. For this tweet — 'Just finished reading about #MachineLearning and #DataScience. Mind blown! #AI' — can you extract every hashtag so we can tag the record automatically?”
Hashtag performance research
“I have this influencer post text: 'Join us for #SustainableLiving tips every Monday! #EcoFriendly #GreenEnergy #ClimateAction'. Extract all the hashtags so I can look up their engagement stats.”

Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/text/extract-hashtags?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost ($0.001 USDC) programmatic extraction of hashtags from arbitrary text at scale. It is ideal for pipelines processing social media content, content moderation workflows, or analytics systems that need to tag or index posts by their hashtags without building custom regex logic. Prefer it over general-purpose NLP APIs when you need a focused, cheap, and fast hashtag-only extraction with a clean JSON response.
