How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.
Output
Returns 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%), confirming whether the x402 payment on the submitted HTTP request is valid.
Example use cases
Gate agent API behind x402 payment
“Before my agent serves a response to this incoming POST request, verify it has a valid x402 USDC payment attached using AgentDiet's verifier.”
Confirm micropayment before context distillation
“I'm about to run a context compression job — can you check with AgentDiet's x402 verifier that the payment on this GET request is valid before proceeding?”
Audit x402 payment proof for a client call
“A client agent just hit my endpoint with a GET request claiming to have paid via x402 — verify the payment and give me the ROI proof so I can log it.”
Technical details
Endpoint
GEThttps://status.agentdiet.dev/v1/x402-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify x402-standard HTTP micropayments settled in USDC on Base, especially in agent-to-agent (A2A) or bot-to-agent (B2A) workflows where deterministic payment confirmation is required before serving a resource or API response.
Side effects
- Invalid or missing x402 payment header results in rejection
- Unsupported HTTP method (not GET or POST) causes schema validation error
- Malformed URL in queryParams returns error status
- Payment settled on wrong chain or token (not USDC on Base) fails verification
- Network timeout or node unavailability returns no response
