AXIOM Tool Pass
Prix plancher 
3,55 $
0 %
Preflight a public HTTPS endpoint before spending. Probes with GET or POST, detects 402/x402 payment requirements, summarizes networks, schemes, payTo recipients, USDC price hints, retryability, Tool Pass auth clues, latency, and evidence, then compares caller expectations (maxUsdc, network, payTo, resource/resourceHost/resourcePath) before any signer is invoked. Blocks localhost/private/IP-literal targets to avoid SSRF. Built for agents deciding whether and how to pay a Base x402 endpoint.

Verify Toolagenttoolindex.xyz
Verifies any ERC-8257 tool. Given a chain_id and tool_id, it reads the tool's onchain registry config, confirms the manifest hash matches the hosted manifest, probes whether the tool's endpoint is live, decodes access predicate and x402 payment requirements, and returns a trust report with a callable verdict. A public-good verification primitive for agents vetting tools before they call them.

BASE167 claim check
BASE167 claim checkbase167.com
Check whether a wallet qualifies for the BASE167 airdrop on Base mainnet and get the transaction to claim it. A wallet qualifies with 167 or more Base transactions. The response carries a short-lived server-signed voucher and ready-to-send calldata: no login, no session, no cookie and no CAPTCHA, and the caller signs nothing. Every wallet type works, including ERC-4337 smart accounts, Base Account, Safe and 7702-delegated EOAs. The wider surface -- the monthly Degen Games trading competition, its boards and its enrolment endpoints -- is documented at https://base167.com/llms.txt and https://base167.com/openapi.json, with an MCP server at https://base167.com/mcp.
