Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/gasWhen to prefer
Use this endpoint when an agent needs a quick, inexpensive ($0.005) real-time gas price check for one of the six supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon, BSC) before executing a transaction or advising a user on timing. Prefer this over full node RPC calls when simplicity and micropayment-based access are acceptable.
Side effects
- Invalid chain value not in enum returns validation error
- Network unavailability on the queried chain may return stale or error response
- Missing required 'input' wrapper in request body causes schema validation failure
- HuggingFace Spaces cold-start delay may cause timeout on first call
