How this service works
Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.
Output
Returns current gas tracker data for the requested blockchain network, including gas price levels (e.g. slow, standard, fast) and estimated transaction costs in native token units. Response format is unstructured (example: {}) so exact fields depend on the network queried.
Example use cases
Pre-transaction gas fee check
“Before I send this ETH transfer, can you check what the current gas prices are on Ethereum so I know how much to budget for fees?”
Base network cost monitoring
“What are the gas fees on Base right now? I'm trying to figure out the cheapest time to mint an NFT.”
Multi-chain gas comparison
“Can you pull the current gas tracker data for the Base chain? I want to compare it with what I'm seeing on other networks.”
Technical details
Endpoint
GEThttps://mcp-x402.onrender.com/x402/gas-trackerWhen to prefer
Choose this endpoint when you need real-time gas fee data for EVM-compatible chains (especially Base) and are already operating in a Web3/x402 micropayment context. It is well-suited for agents that autonomously pay per call in USDC without requiring API key management. Prefer alternatives (e.g. Etherscan gas oracle, Blocknative) if you need detailed gas history, guaranteed SLAs, or structured response schemas.
Side effects
- Missing or invalid 'chain' query parameter may return an error or default network data
- Unknown chain identifier returns an error or empty response
- Payment failure via x402 (insufficient USDC, wrong network) blocks the request entirely
- Service unavailable on Render free tier cold-start delays
- Rate limiting if many calls are made in rapid succession
