How this service works
Market intelligence for any x402 endpoint or operator wallet. Returns settlement volume, unique payer count, price range, reputation tier, activity window, and endpoint description — drawn from 4.1M+ Base mainnet settlements in the Stall's proprietary on-chain dataset. Use before routing agent spend, vetting a counterparty operator, or benchmarking competitor pricing. No external API. Covers 80,000+ operators across 10+ days of live traffic.
Output
Returns structured intelligence about the queried x402 endpoint or operator wallet, including pricing in USDC, input/output schemas, capability description, payment requirements, and operator metadata from the IntuiTek marketplace.
Example use cases
Example prompt
“Can you look up the x402 endpoint intelligence for https://example-api.com/some-endpoint and tell me its price, input schema, and what it does?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/x402-endpoint-intelWhen to prefer
Use this endpoint when an AI agent needs to discover or verify the capabilities, pricing, and schema of an x402-compatible API before calling it, or when inspecting an operator wallet to enumerate available services. Prefer this over generic API discovery tools when working specifically within the x402 micropayment ecosystem on Base mainnet.
Side effects
- Target URL is not an x402-enabled endpoint — returns no data or error
- Wallet address not found in the operator registry
- Malformed URL or invalid wallet address format causing a 400-class error
- Endpoint metadata not yet indexed by The Stall — returns empty result
- Payment of 0.02 USDC not fulfilled, resulting in 402 Payment Required response
