How this service works

Universal B2A/A2A/MCP Meta-Router & Autonomous Tool Marketplace indexing 7,340+ live capabilities across x402 v2 (5-chain EVM USDC), IETF MPP, and L402 with TDQS quality scoring and zero-fee pass-through execution.

Output

Returns a JSON object with a 'data' field containing ranked tool/API/agent listings matching the query, a 'status' field confirming success, and an 'roi_proof' object including a compression_ratio_pct showing how much of the indexed universe was distilled into the response.

Example use cases

Finding a web scraping tool for an agent

“Search the X402-Broker index for any available MCP servers or x402 APIs that can scrape web pages or extract structured data from URLs — I need the best-ranked ones.”

Discovering DeFi trading tools

“Can you query X402-Broker to find me all available autonomous agent tools or APIs that handle DEX trading or DeFi alpha signals, sorted by quality?”

Locating a code execution capability

“Look up X402-Broker for any live MCP servers or APIs that let an AI agent execute Python or JavaScript code in a sandbox environment.”

Technical details

Endpoint

When to prefer

Use this endpoint when an AI agent needs to dynamically discover the best available tool, MCP server, or x402-compatible API for a given task at runtime — especially when the specific capability is not hardcoded and needs to be looked up from a large index. Prefer this over static tool registries when you want TDQS quality scoring, multi-protocol support (x402, L402, IETF MPP), and a single unified search across 7,000+ live endpoints.

Side effects

Missing required 'input' object returns validation error
Invalid HTTP method enum value causes schema rejection
Empty or too-broad query may return low-relevance results
Payment of $0.01 USDC not fulfilled causes 402 response
Service unavailability results in non-200 status
