x402
ChainRay Stablecoin Supply is a paid API for AI agents from chainray.online, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Returns total and circulating supply of stablecoins (e.g., USDC, DAI) for a specified blockchain network, with on-chain proof and global market context.

How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns a JSON object containing per-stablecoin supply data (symbol, contract address, totalSupply as raw number and formatted string), aggregated cross-chain totals, global DeFi Llama market context, a block-anchored cryptographic proof (blockHash, blockNumber, blockTimestamp, dataHash), and the chain scanned.
Example use cases
Validate stablecoin reserves for lending protocol
“Can you pull the total USDC and USDT supplies on Ethereum and Polygon so I can verify our collateral reserves are properly backed? I need the on-chain proof too.”
Monitor cross-chain stablecoin liquidity
“I need to see how much DAI and USDC are circulating on Arbitrum, Optimism, and Base right now — help me identify which chains have the deepest stablecoin pools.”
Risk assessment for stablecoin exposure
“Get me the verified total supply of all major stablecoins on Ethereum with block anchors so I can assess our counterparty risk and ensure the data is cryptographically sound.”
Technical details
Endpoint
GEThttps://chainray.online/stablecoin-supplyWhen to prefer
Use this endpoint when you need real-time, on-chain verified stablecoin supply figures for a specific blockchain with cryptographic proof of data integrity. Prefer this over generic market data APIs when you need per-chain granularity, contract-level supply breakdowns, and block-anchored provenance rather than aggregated global estimates.
Side effects
- Unsupported chain name returns empty or error response
- Chain parameter typo causes no results
- Network congestion may cause delayed block data
- RPC node unavailability may cause timeout
- Stablecoin not deployed on specified chain returns no entry for that symbol
