How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok'), a data object containing the scan results, and an roi_proof object that includes a compression_ratio_pct value (e.g. 91.4%) indicating how much the content could be compressed for context window optimization.
Example use cases
Pre-fetch paywall check for RAG pipeline
“Before I try to pull content from https://nytimes.com/2025/01/01/tech/ai-agents.html into my RAG pipeline, can you scan it to see if it's paywalled and what compression ratio I'd get?”
Content accessibility audit for agent workflow
“I need to know if https://wsj.com/articles/some-story is behind a paywall before routing my agent to fetch it — can you run a paywall scan on that URL?”
Token budget planning before context injection
“Scan https://medium.com/@author/long-article for me — I want to know if it's gated and what the expected compression ratio would be so I can plan my token budget.”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/paywall-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically check whether a target URL is behind a paywall before committing tokens or downstream pipeline steps to fetching its content. Particularly useful for AI agents managing token budgets, RAG pipelines that need to pre-qualify content sources, or workflows that need to avoid wasting API calls on gated content. The compression ratio output also makes it useful for planning context window usage before ingestion.
Side effects
- Invalid or unreachable URL returns an error status
- Missing required 'input' object causes schema validation failure
- Non-HTTP URL type returns a validation error
- Payment not settled in USDC on Base results in 402 payment required response
- Rate limiting or access restrictions on the target URL may prevent scanning
