POST /v1/defi/stablecoins

blocked

Stablecoin market data with the number agents paying in USDC actually need: current price and PEG DEVIATION per coin, circulating supply, peg mechanism and chains, ranked by market cap. Filter by symbol or screen for depegs (absolute deviation above a threshold). Open DefiLlama data, refreshed every 10 minutes.

Verdict: not verified by an unpaid GET. 401/403/429: auth or bot protection. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://agentbit.app/v1/defi/stablecoins' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
