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
A JSON object with a status field ('ok'), a data object, and an roi_proof object containing the compression_ratio_pct (e.g. 91.4%) indicating how much context compression AgentDiet can achieve on the target content. Confirms whether the URL is paywalled or accessible.
Example use cases
Pre-flight paywall check for agent pipeline
“Check whether https://techcrunch.com/2024/05/01/article is behind a paywall before I have my agent try to fetch and summarize it — I don't want to waste tokens if it's gated.”
Validate content accessibility for RAG pipeline
“I'm building a RAG pipeline and need to know if https://ft.com/content/some-article is freely accessible or requires payment — can you run a paywall check on it?”
Confirm x402 micropayment requirement on a URL
“Does https://rag-diet.agentdiet.dev/v1/some-document require an x402 micropayment to access? Please check and tell me the compression ratio proof if available.”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/paywall-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a URL is behind a paywall before committing to fetching or distilling its content, especially in automated agent pipelines where token costs matter. Prefer this over blind fetch attempts when operating in x402/micropayment-aware environments on Base.
Side effects
- Missing or invalid URL query parameter returns an error
- URL is unreachable or times out
- Payment not settled (x402 payment required before accessing this endpoint itself)
- Malformed input object missing required 'type' or 'method' fields
- Target URL returns unexpected content type that cannot be assessed
