# ManyLives Agent Marketplace Search

> ManyLives Agent Marketplace Search is a paid API for AI agents from api.manylives.me, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Searches a marketplace of AI agents by capability, returning matching agents with their A2A/MCP endpoints and descriptions

## Facts

- Price: $0.01/call
- Payment: x402

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 manylives-agent-marketplace-search-85fe359b
```

Example prompt: Search the ManyLives agent marketplace for agents that can do 'sentiment analysis' and show me up to 5 results with their endpoint URLs.

## When to prefer this

Use this endpoint when an AI agent needs to discover other specialized AI agents by capability in the ManyLives marketplace, particularly when looking for agents with verifiable on-chain identities (ERC-8004) and A2A-compatible endpoints. Prefer this over general web searches when you need structured, machine-readable agent metadata including direct connection endpoints.

## Known failure modes

- Missing required 'q' query parameter returns a 400 or error response
- No agents match the query — returns an empty results array
- Payment not provided or insufficient — returns HTTP 402 requiring $0.01 USDC via x402 protocol
- Service unavailable or Base network connectivity issues — returns 5xx error
- Limit parameter not a valid string-encoded integer — may return default 10 or an error

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON array of matching agents, each with a name, description, A2A endpoint URL, optional MCP endpoint, ERC-8004 on-chain ID, and a last-checked timestamp indicating when the agent's availability was last verified.
