Output
A list of x402 API routes (URLs, methods, and descriptions) that collectively address the submitted task or sub-tasks, along with a total price estimate in USDC for executing all identified routes.
Example use cases
Multi-step agent workflow planning
“I want my agent to verify a wallet address for sanctions, find related court cases, and check patent filings for a company — can you discover which x402 API routes cover all of that and give me an estimated cost upfront?”
Single-task API route discovery
“I need to screen an Ethereum wallet address for OFAC sanctions violations — which x402 API should I use for that, and what will it cost?”
Exploratory capability search
“I'm building an AI agent that needs to look up ERC-20 token holders and search US court dockets — can you find the right x402 endpoints for those two tasks and estimate the total price?”
Technical details
Endpoint
POSThttps://x402helper.xyz/discovery?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402 APIs to call for a given task, especially for multi-step workflows where the right combination of endpoints is not known in advance. Prefer it over hardcoded routing when tasks are described in natural language or when you want an upfront cost estimate across multiple API calls.
Side effects
- Task description is too vague to match any routes — returns empty route set
- No x402 APIs available that match the requested capability
- Ambiguous sub-tasks result in overlapping or redundant route suggestions
- Price estimate may be stale if underlying endpoint pricing has changed
- Natural language parsing fails on highly technical or domain-specific requests
