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 payload, and an roi_proof object containing the compression_ratio_pct (e.g. 91.4%), confirming whether the target URL is x402-compliant and how much token reduction is achievable.
Example use cases
Pre-flight x402 payment check
“Before my agent calls that paid API, can you verify if https://api.someservice.com/data is x402-compliant and will accept USDC micropayments — run a GET probe on it?”
Token compression ROI validation
“I want to know if AgentDiet can meaningfully compress https://docs.example.com/guide before I pay to distill it — can you run the x402 verifier on it as a GET to see the projected compression ratio?”
Agent pipeline x402 eligibility gate
“My workflow needs to confirm that https://news-feed.example.com/latest is x402-enabled and returns a valid verification status before we route it through the distillation pipeline — can you check it?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/x402-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to confirm x402 protocol support and payment eligibility for a target URL before committing to a paid distillation or API call. Prefer it over generic HTTP probers when you also need a compression ROI estimate, or when building agent pipelines that gate on x402 compatibility.
Side effects
- Missing or invalid 'url' query parameter returns error
- Target URL unreachable or returns non-HTTP response
- URL does not support x402 protocol — verification fails with non-ok status
- Payment not settled in USDC on Base — request blocked
- Malformed input object missing required 'type' or 'method' fields
