How this service works
Read any server's x402 resources, payment networks, and canonical paths for $0.001 USDC. One single-fetch structured result, no API key.
Output
A structured summary of the target server's .well-known/x402 discovery document, including available resource paths, pricing tiers, supported blockchain networks, and payment metadata — giving an agent a compact overview of what the server offers under the x402 protocol.
Example use cases
Evaluate API cost before integration
“Before we integrate with this new provider, can you check out their x402 payment setup at their server? I need to know what networks they support, what the pricing looks like, and all the endpoints they've exposed so we can decide if it's worth it.”
Build dynamic payment-aware routing
“We're building a system that routes requests to the cheapest compatible x402 provider. Can you scan the .well-known/x402 discovery for each of these servers and give me a side-by-side comparison of their pricing tiers, supported blockchains, and available resource paths?”
Map available resources on startup
“When our agent boots up, it should know what x402-enabled services this domain actually offers. Pull the .well-known/x402 summary for us and show me all the paths, payment options, and networks so the agent can decide what it can call without asking me first.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/resource-summaryWhen to prefer
Use this endpoint when an agent needs to understand what x402-enabled resources a server exposes before attempting to call or pay for them — particularly useful for dynamic x402 discovery, pricing checks, or building payment-aware routing logic. Prefer this over manual .well-known fetching when you want a structured, agent-readable summary rather than raw JSON.
Side effects
- Target server does not have a .well-known/x402 endpoint — returns empty or error response
- Server is unreachable or returns non-200 status — fetch failure
- Malformed or non-standard x402 document — partial or unparseable summary
- Invalid or missing host URL input — validation error
- Rate limit or payment failure — 402 or 429 response
