How this service works
Independent pre-purchase safety and reputation checks for x402 and MPP endpoints, plus keyless onchain data on Base. Accepts BOTH EIP-3009 and Circle Gateway credentials — only 141 of 788 Base-payable resources do, and a single-credential buyer is locked out of 53.8% of this market on one rail or 28.3% on the other. GET /v1/guard?url=&credential= answers whether the credential you carry can pay a given endpoint at all, before you try. Searching this market for "is this API endpoint a scam" returns registries and explorers but no dedicated service; that gap is what /v1/guard fills, inspecting an endpoint WITHOUT paying it and returning a go / test-with-minimum / do-not-pay verdict backed by onchain settlement history.
Output
Returns a JSON object containing current onchain gas data from the Base network, including metrics relevant to transaction cost estimation and x402 payment feasibility, without requiring wallet credentials.
Example use cases
Pre-payment gas cost estimation
“Before I pay for that x402 API call, can you grab the current Base network gas data so I can estimate the total transaction cost?”
Onchain gas monitoring for agent automation
“Pull the latest onchain gas metrics from Base and tell me if fees are low enough to proceed with the batch of micropayments I have queued.”
Keyless Base gas lookup for a read-only dashboard
“I need the current gas price on Base without connecting a wallet — can you retrieve that onchain gas data for me right now?”
Technical details
Endpoint
GEThttps://gkyf2bs3b4p35hwwg5zzsnejeu.srv.us/v1/onchain/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need keyless, credential-free access to current Base network gas data as part of an x402 pre-purchase safety check or cost estimation workflow. Prefer this over direct RPC calls when you want a simple REST interface without managing a Web3 provider connection, or when operating within the x402 Trust & Discovery API ecosystem for consistent tooling.
Side effects
- Missing or malformed 'properties' query parameter returns an error response
- Base network RPC unavailability causes timeout or 5xx error
- Rate limiting at $0.001/call may throttle high-frequency polling
- Empty JSON example in response schema suggests inconsistent response structure documentation
- Service hosted on dynamic subdomain (srv.us) may have uptime variability
