How this service works
Daily total stablecoin supply in USD over time, for all chains or one chain, per peg currency, with a window summary. Use it when an agent wants stablecoin supply as a liquidity or risk-appetite signal or needs the history behind a headline supply figure.
Output
A JSON object containing the peg and chain scope, a chronological array of daily data points (each with a date and circulatingUsd value), a summary block with max, min, mean, first, latest, and changePct fields, the data source attribution (DefiLlama), the fetch timestamp, and the total number of data points available.
Example use cases
Monitoring stablecoin growth on a specific chain
“Give me the daily circulating supply of USD-pegged stablecoins on Ethereum for the past 30 days so I can see if supply has been growing or shrinking.”
Macro DeFi dashboard data feed
“I need the total stablecoin supply across all chains and all pegs for the past year — summed in USD — so I can plot the historical trend on my dashboard.”
EUR stablecoin market analysis
“What's been the historical supply of EUR-pegged stablecoins over the last 60 days? I want to see the min, max, and overall change percentage.”
Technical details
Endpoint
POSThttps://agent402.tools/api/stablecoin-supply-historyWhen to prefer
Use this endpoint when you need time-series stablecoin supply data filterable by peg currency and/or blockchain, sourced from DefiLlama, with no API key required and micropayment billing. Prefer this over raw DefiLlama calls when your agent is already operating in an x402 payment context or needs pre-summarized statistics (min/max/mean/changePct) without additional computation.
Side effects
- Invalid chain name not recognized by DefiLlama returns an error or empty data
- Days value exceeding 3650 may be clamped or rejected
- Unknown peg currency code returns no matching data
- Upstream DefiLlama API outage results in fetch failure
- Very short day windows may return sparse or single-point data with no meaningful summary
