How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 on Base.
Output
A short plain-text summary of the submitted content, capped at the requested max_words (default 60, maximum 250). The service refuses input exceeding 8,000 characters rather than silently truncating it. Payment of $0.005 USDC is collected in-band via x402 on Base as part of the request.
Example use cases
Quick product blurb for listing
“Take this long manufacturer description and summarize it in 40 words so I can use it as a short blurb on our marketplace listing: 'The HydroFlask Trail Series 32oz water bottle features double-wall vacuum insulation keeping drinks cold for 24 hours or hot for 12, an ergonomic flex cap, and is made from 18/8 pro-grade stainless steel.'”
Digest scraped article content
“I just scraped the body text from a news article — can you condense it down to a 60-word summary? Here's the text: 'Scientists at MIT announced a breakthrough in solid-state battery technology Tuesday, claiming their new lithium-ceramic composite achieves energy densities three times higher than conventional lithium-ion cells while eliminating fire risk. The team published findings in Nature Energy and expects commercial prototypes within five years, pending industry partnerships.'”
Briefing bullet for research agent
“Summarize this technical abstract in no more than 80 words so I can paste it into my briefing doc: 'Quantum key distribution (QKD) leverages the principles of quantum mechanics to enable two parties to generate a shared, provably secret random key. Unlike classical cryptography, any eavesdropping attempt introduces detectable disturbances in the quantum channel, alerting legitimate users to interception attempts. Recent experiments have demonstrated QKD over fiber distances exceeding 400 km using twin-field protocols.'”

Endpoint
POSThttps://extract.tollkit.dev/summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-demand text summarization with no prior account setup, API key provisioning, or subscription — just pay $0.005 USDC per call via x402 on Base. Ideal for agents that occasionally need summaries without committing to a SaaS plan, or for workflows that must stay stateless and credential-free. Well-suited for texts under 8,000 characters where a word-capped output (up to 250 words) is sufficient.
Side effects
- Text exceeds 8,000 characters — request is refused outright rather than truncated
- Payment failure or insufficient USDC balance on Base — transaction rejected before processing
- max_words value exceeds 250 — clamped silently to 250
- Missing or malformed text field — likely a 400-level validation error
- Network or upstream LLM failure — service unavailable or timeout
