How this service works
Blockchain Gateway Service
Output
Returns a JSON object with a status field (e.g. 'ok') and likely includes current USDC supply or token circulation data from the blockchain gateway. Exact supply figures depend on the live chain state at time of query.
Example use cases
DeFi dashboard USDC supply widget
“Pull the current USDC on-chain supply from Chain Vault so I can display it on my DeFi analytics dashboard.”
Stablecoin supply monitoring alert
“Check the USDC supply through the Chain Vault gateway and let me know if the number has changed significantly since yesterday.”
Crypto research report data fetch
“I need the latest USDC circulating supply data from the Chain Vault blockchain gateway for a stablecoin market research report I'm putting together.”
Technical details
Endpoint
GEThttps://x402-tc-agent-server.vercel.app/api/supply-usdc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call access to USDC supply data via the x402 micropayment protocol on a serverless blockchain gateway. It is appropriate for agents that already handle x402 payment flows and need lightweight, on-demand supply lookups without a persistent API key subscription.
Side effects
- Payment not received or insufficient USDC balance results in 402 Payment Required response
- Blockchain node or gateway downtime causes 503 or timeout
- Malformed or missing required query parameters return 400 Bad Request
- Rate limiting may return 429 if called too frequently
- Response may return status 'ok' with incomplete data if chain sync is lagging
