Stablecoin Circulating Supply with On-Chain Cross-Check
x402
Stablecoin Circulating Supply with On-Chain Cross-Check is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).
Returns the total circulating supply and per-chain breakdown of a stablecoin from DefiLlama, cross-validated against a live on-chain ERC-20 totalSupply read, with a divergence flag if they disagree beyond tolerance.

How this service works
Supply facet for a stablecoin: total circulating supply plus the per-chain breakdown from DefiLlama, cross-checked against an INDEPENDENT on-chain ERC-20 totalSupply read of the curated contract, with a divergence flag when the two disagree beyond a tolerance. Cited to both the open-data source and public on-chain state.
Output
Returns total circulating supply of the requested stablecoin, a per-chain breakdown sourced from DefiLlama, the on-chain ERC-20 totalSupply read from the curated contract on the specified chain, and a divergence flag indicating whether the two sources disagree beyond an acceptable tolerance, with citations to both data sources.
Example use cases
Example prompt
“What's the current total circulating supply of USDC, broken down by chain, and does the DefiLlama number match what the on-chain contract actually shows? Check on Ethereum if you need to pick a chain for the cross-check.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/stablecoin/supplyWhen to prefer
Use this endpoint when you need both an aggregated multi-chain circulating supply figure AND independent on-chain verification in a single call. Prefer this over a plain DefiLlama query when data integrity and source divergence detection matter, or when you need to cite both off-chain aggregated and raw on-chain state for a stablecoin supply figure.
Side effects
- Unknown stablecoin symbol or id returns a 404 or error indicating the token was not found
- Unsupported chain for on-chain cross-check may return partial data without the on-chain verification component
- Contract address not found or malformed returns an error
- DefiLlama data temporarily unavailable may result in incomplete breakdown
- RPC/on-chain read failure may return DefiLlama data only with a note that on-chain cross-check failed
