# B2B Lead Enrichment Workflow (agentdiet)

> B2B Lead Enrichment Workflow (agentdiet) is a paid API for AI agents from email-verify.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches a meta-index of 500+ MCP servers and A2A tools to discover relevant capabilities or verify endpoints, with prompt-guard firewall and token-compressed results.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability email-verify-agentdiet-dev-b2b-lead-enrichment-workflow-agentdiet-24ebac83
```

Example prompt: Search the agentdiet tool index for MCP servers or A2A agents that can do B2B lead enrichment and company data lookup — I want to see what's available with token-compressed results.

## When to prefer this

Use this endpoint when an agent needs to discover which MCP servers or A2A tools are available for a given capability without connecting to each one individually, or when you need to verify whether a specific endpoint URL is a known, compliant MCP server. Prefer this over manual tool registries when you need token-efficient results and prompt-injection protection built in.

## Known failure modes

- Missing or empty 'query' parameter returns a 400 validation error
- Query that matches no indexed tools returns an empty result set
- Endpoint URL verification may return 'not found' if the URL is not in the index
- Service may return HTTP 402 if payment header is missing or invalid
- Overly broad queries may return too many low-relevance results

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://email-verify.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output

Returns a token-compressed list of matching MCP servers, A2A tools, or endpoint verification results relevant to the query, including capability descriptions and routing metadata, filtered through a Prompt-Guard firewall.
