Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/chainlink-price?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost, no-account-required spot price for Chainlink (LINK) in USD, especially in an agentic or automated workflow that can pay per-call in USDC on Base via x402. Prefer this over heavier exchange APIs when you only need a single price point and want zero-setup access.
Side effects
- Payment failure if USDC balance on Base is insufficient — returns 402 Payment Required
- Oracle data unavailability — may return stale or missing price if Chainlink feed is lagging
- Malformed response if the upstream price feed is temporarily unreachable
- Rate or network issues on duckdns.org domain (non-enterprise hosting)
