How this service works
URL and content micro-tools for AI agents: parse URLs, probe HTTP status and security headers, extract text from HTML, text stats, and similarity. Pay with USDC via x402 — no API keys.
Output
Returns a JSON object with an 'ok' boolean and a similarity score or metric indicating how similar the two input texts are, likely as a float between 0 and 1.
Example use cases
Deduplication of product descriptions
“I have two product descriptions and I want to know if they're saying the same thing — compare 'Lightweight waterproof hiking boots with ankle support' and 'Ankle-height trail boots, water-resistant and featherlight' and give me a similarity score.”
Resume-to-job-description matching
“Can you check how well this resume summary matches the job description? Resume: 'Experienced Python developer with 5 years in data engineering and pipeline automation.' Job: 'We need a senior data engineer skilled in Python and ETL workflow development.'”
Plagiarism detection for student submissions
“Compare these two essay excerpts and tell me how similar they are — I want to know if one might be copied from the other: 'Climate change is driven primarily by greenhouse gas emissions from human industry' versus 'Human industrial activity and greenhouse gases are the main cause of climate change.'”

Endpoint
POSThttps://agent-link.annushka1190.workers.dev/v1/text/similarityWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call text similarity computation without managing API keys or standing up an NLP service. It is ideal for agents that need on-demand similarity checks for deduplication, matching, or ranking tasks and want to pay in USDC via x402 with minimal setup.
Side effects
- Missing required 'input' body fields returns a 4xx validation error
- Non-text or empty string inputs may produce a zero or undefined score
- Payment failure via x402 results in a 402 response requiring USDC payment
- Very long text inputs may exceed processing limits and return a 4xx or timeout
- Network timeouts to the Cloudflare worker may occur under load
