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 the tool execution result, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct metric indicating how much token compression was achieved during routing.
Example use cases
Research tool discovery and execution
“I need to find and run the best available tool across your indexed MCP servers to pull recent AI safety papers from ArXiv — search for it and execute a GET query for 'AI safety 2024 papers'.”
Agent capability routing for data enrichment
“Route my query through your meta-index to find an MCP server that can enrich a company name with contact data — execute a GET lookup for 'Acme Corp company enrichment'.”
Single-call access to A2A agent network
“Use the X402-Broker to find and execute the best A2A agent for summarizing a Slack thread — run a GET query for 'summarize conversation transcript' against your indexed tools.”
Technical details
Endpoint
GEThttps://x402broker.com/v1/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single unified interface to discover and execute against thousands of MCP servers, x402 APIs, and A2A agents without managing individual integrations. It is especially useful when you do not know which specific tool is best for a task and want the broker to route to the highest-quality match using TDQS scoring. Prefer it over direct API calls when your agent operates across multiple capability domains and needs zero-fee pass-through execution with USDC micropayments.
Side effects
- No matching tool found for the given query — empty data payload returned
- Payment failure or insufficient USDC balance — request rejected before execution
- Invalid input schema (missing required 'type' or 'method' fields) — validation error
- Upstream MCP server or API unavailable — timeout or error propagated in data field
- Query string too vague to route to a specific capability — low-confidence match returned
