x402
P0 Agent Economy Index – Registry Route is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.032/call, status unknown (last checked 2026-10-17).
Returns ranked discovery data for agent registry protocols (Virtuals ACP, Olas, Masumi, ERC-8004, Solana, Base, MCP) with per-protocol published figures such as agent/server counts, transaction events, payers, and USD volume.

How this service works
An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.
Output
A JSON response listing matched registry-tagged services, each with protocol name, agent or server count, transaction or payment event figures, payer counts and USD volume where the source publishes them, along with the data window, source attribution, snapshot hash, and scoring revision timestamp. Units differ across protocols so figures are not summed into a total.
Example use cases
Comparing active agent registry protocols
“I'm evaluating which agent registry ecosystems are actually gaining traction — can you pull the latest index for all major registries like Olas, Virtuals ACP, Masumi, and MCP servers, and show me their agent counts, transaction events, and any volume figures available?”
Tracking MCP server growth over time
“How many servers are currently in the official MCP Registry, and how does that compare to other agent protocol registries? Pull the most recent snapshot from the agent economy index so I can see the full picture.”
Due diligence on agent economy scale
“Before I invest in building on an agent protocol, I want to know which ones have the most real activity — can you get me the agent economy registry index showing transaction events, payer counts, and USD volume for each protocol that publishes those numbers?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-registry?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cross-protocol, normalized view of the agent registry ecosystem (Virtuals ACP, Olas, Masumi, ERC-8004, Solana, Base, MCP) with official published figures. Prefer this over the x402 market index routes when your focus is on agent/server registry counts and protocol-level activity rather than individual x402 service rankings. Ideal for market research, competitive analysis, or due diligence on agent economy scale.
Side effects
- Payment not included or malformed — endpoint requires $0.032 USDC via x402 protocol, returns 402 Payment Required
- Invalid or unsupported tag parameter — returns empty result set or 400 error
- Snapshot data stale if underlying registry sources have not refreshed — generatedAt timestamp indicates data age
- Protocol source temporarily unavailable — partial result set returned with available protocols only
- Rate limit or quota exceeded — returns 429 Too Many Requests
