Technical details
Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/chain-status?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to time or budget a Base chain transaction — specifically when the agent must decide whether current gas costs are acceptable before submitting, or when it needs to convert gas costs to USD for budget checks. Prefer this over generic ETH price feeds when you need gas fee data alongside price in one call on Base specifically.
Side effects
- 402 Payment Required: endpoint returns payment requirements; agent must pay $0.005 USDC on Base to 0x973a31858f4d2125f48c880542da11a2796f12d6 and retry
- Network or upstream RPC unavailability may cause stale or missing block data
- Payment verification failure if USDC transfer is malformed or underpaid
- Rate limiting or relay infrastructure errors returning 5xx
