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
A paginated list of matching MCP servers, x402 APIs, or A2A agent tools with their metadata (names, descriptions, endpoint URLs, pricing, tags), plus an opaque pagination cursor for fetching additional results.
Example use cases
Discovering SEC filing tools for finance agents
“Search the X402-BROKER MCP gateway for up to 10 APIs or tools related to 'SEC filings' so I can find a capability my agent can call to retrieve company financial disclosures.”
Finding GitHub security scanning MCP servers
“Can you query the X402-BROKER gateway for MCP servers or A2A agents that handle 'github security' scanning? Return up to 20 results.”
Verifying a specific endpoint exists in the registry
“Check the X402-BROKER meta-index to see if the endpoint 'https://someprovider.com/v1/enrich' is listed and verified as a live capability.”
Technical details
Endpoint
GEThttps://x402broker.com/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which MCP servers, x402 APIs, or A2A agents exist for a given capability, rather than hard-coding tool endpoints. It is especially useful for building agent orchestration layers, tool marketplaces, or routing logic that must select from thousands of available tools at runtime. Prefer this over manually maintaining a list of APIs or using a narrower single-provider registry.
Side effects
- Empty query string — returns validation error since query is required and minLength is 1
- No matching results for obscure or misspelled capability queries — returns empty result set
- Limit out of range (below 1 or above 100) — returns schema validation error
- Invalid pagination cursor — returns error or restarts from beginning
- Gateway may return stale index data if upstream MCP servers have gone offline
