# Bot Bazaar x402 Directory Dataset

> Bot Bazaar x402 Directory Dataset is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Downloads a cleaned, verified dataset of Base USDC x402 payment endpoints and MCP servers, optionally filtered by category or format (JSON/CSV).

## Facts

- Endpoint: GET https://bot-bazaar.fly.dev/v1/x402/directory-dataset?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-30
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/bot-bazaar-x402-directory-dataset-4c1b42ba
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_I1PaRiENZb4m7j2W3A6gP

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 bot-bazaar-x402-directory-dataset-4c1b42ba
```

Example prompt: Pull the full Bot Bazaar x402 endpoint directory as JSON, filtered to the ai-inference category, so I can see which verified USDC payment APIs are available.

## When to prefer this

Use this endpoint when an agent needs a machine-readable snapshot of all available x402-compatible micropayment APIs on the Base network, especially for building tool registries, comparing service prices, or discovering MCP servers. Prefer this over manual web scraping of API marketplaces when you specifically need x402/USDC-compatible endpoints with verified pay-to addresses and pricing metadata.

## Known failure modes

- Invalid format parameter — must be 'json' or 'csv'; unrecognized values may be ignored or return an error
- Invalid or unrecognized category filter returns an empty items[] array rather than an error
- Payment of $0.01 USDC via x402 not completed — returns 402 Payment Required before dataset is served
- Stale data if last_verified timestamps are old and endpoints have changed since last crawl
- Network timeout on fly.dev cold start if instance was auto-stopped

## How this service works

Downloadable cleaned JSON + CSV dataset of verified Base USDC x402 endpoints and MCP servers (category, service_name, url, method, price_usdc, network, asset, pay_to, has_bazaar_schema, mcp_endpoint, last_verified). Excludes operator/house financial figures.

## Output

Returns a structured dataset containing all verified x402 endpoints and MCP servers registered in Bot Bazaar, including fields: category, service_name, url, method, price_usdc, network, asset, pay_to, has_bazaar_schema, mcp_endpoint, and last_verified. Response includes both an items[] array and a csv text field. Operator/house financial data is excluded.
