Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/base-gas-snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a real-time, point-in-time snapshot of the Base x402 transfer fee from the canonical rail index — particularly before routing a payment, auditing settlement costs, or deciding whether to transact on Base at the current fee level. Prefer this over generic gas estimation APIs when working specifically within the x402 payment protocol on Base.
Side effects
- Payment required (402) if no x402 payment header is included and meta=1 is not set
- Invalid method (only GET, HEAD, DELETE accepted)
- Stale or unavailable rail index data leading to outdated fee snapshot
- Network timeout from k2so.wrong.systems
- Invalid queryParams value for meta field (must be '0' or '1')
