Binance launched B402 Bazaar in June 2026 — an agent payment marketplace on BNB Chain with CoinMarketCap data, gas-sponsored transactions, and Trust Wallet integration. It's the most well-funded competitor in the agent discovery space.
But what's actually in the catalog? How many endpoints? What kinds of services? Who's listing?
The B402 Bazaar has a public, read-only API — no authentication required. So I queried it directly. Here's what I found.
GET https://www.binance.com/bapi/ramp/v1/public/ramp/b402/bazaar/resources
Response: 25 items. That's the entire catalog.| Provider | Endpoints | % of Catalog | Service Type |
|---|---|---|---|
| Xona Agent | 13 | 52% | AI inference (LLM, image, audio, video) |
| CoinMarketCap | 4 | 16% | Crypto market data (exclusive) |
| HyreAgent | 3 | 12% | DeFi (yield, cross-chain, LP) |
| WealthPulse | 2 | 8% | Financial data |
| Other (3 providers) | 3 | 12% | Health, image gen |
Xona Agent alone accounts for 13 of 25 listings (52%). The catalog is not a diverse marketplace — it's a small collection dominated by a single AI API reseller. For comparison, minia2a lists 307 endpoints from multiple independent providers across 10+ categories.
All 25 endpoints use eip155:56 (BNB Smart Chain mainnet). If your agent isn't on BNB Chain — or if you prefer Base, Arbitrum, Polygon, or any other chain — B402 Bazaar has nothing for you. minia2a is facilitator-agnostic: services can accept payment on any chain they choose.
The B402 catalog contains no trial mechanism. No health probes. No verification that endpoints actually respond. An agent must pay before discovering whether the service works. minia2a offers 5 free trial calls (register a wallet) and continuously probes endpoint health, deactivating dead services.
The amount field in the B402 response is empty for all 25 listings. Agents can't compare prices without initiating a payment flow. minia2a displays prices directly in the catalog (priceCents field) and in machine-readable 402 headers (x-402-amount, x-credits-required).
B402 has LLM inference endpoints (GPT-5.2, Claude Opus 4.6, Gemini 3.5 Flash), AI image generation, TTS, and video generation. These are high-value services. But there's no /api/agent-ready endpoint, no MCP server for Claude Code integration, and no .agent-budget convention. An autonomous agent can't self-onboard.
| Dimension | Binance B402 Bazaar | minia2a |
|---|---|---|
| Catalog size | 25 | 307 |
| Chains supported | BNB Chain only | Chain-agnostic |
| Trial-first access | None | 5 free trial calls |
| Health probes | None | Continuous, auto-deactivate |
| Price transparency | Hidden in catalog | Displayed + machine-readable headers |
| Agent-ready endpoint | None | GET /api/agent-ready |
| MCP server (Claude Code) | None | npm: minia2a-mcp v1.1.5 |
| Gas sponsorship | Sponsored by B402 | Standard gas |
| Exclusive data | CoinMarketCap (4 endpoints) | No exchange exclusives |
| Registration | BNB Agent Studio | One curl command |

Credit where it's due. B402 has two things minia2a doesn't:
Binance also has the brand, the distribution, and the Trust Wallet integration. These are real advantages that shouldn't be dismissed.
B402 = single-chain, gas-sponsored, AI-heavy. Binance is building an agent payment rail tightly integrated with BNB Chain. The catalog is curated (25 high-quality endpoints) and optimized for Binance's ecosystem.
minia2a = chain-agnostic, trial-first, verification-first. minia2a is building an open discovery layer where any agent on any chain can find, test, and pay for APIs. The catalog is broad (307 endpoints) and health-verified.
These are not the same product. They're making different bets about how the agent economy will develop. B402 bets on vertical integration (chain + wallet + catalog + data). minia2a bets on open discovery (any chain, any facilitator, trial-first).
Claude Code auto mode goes default in 2 days. Millions of agents will have permission + budget + payment rails. The question: where do they discover APIs to spend that budget on?
B402 has 25 endpoints on BNB Chain. minia2a has 307 endpoints across chains. Neither catalog is large enough to serve the full range of agent needs — but minia2a's catalog is 12x larger, trial-first, and health-verified.
For the Claude Code user on Aug 14:
npx -y minia2a-mcp → 307 APIs, 5 free trials per identity, any chain. 30-second setup. Machine-readable 402 headers for auto-pay.The platform that's easiest to integrate and safest to try will win the first wave of auto-mode agents. B402 has the brand. minia2a has the developer experience.
Binance B402 Bazaar is real — but it's early. 25 endpoints, one dominant provider, BNB Chain only, no trials, no health verification. It's a v0.1 product with v1.0 brand backing.
The agent discovery layer is still wide open. No platform — not Binance, not Coinbase, not minia2a — has achieved critical mass. The window is open. The question is who executes faster on the things autonomous agents actually need: trial-first access, health verification, and machine-readable everything.
Methodology: B402 Bazaar data collected via direct API query to the public /bazaar/resources endpoint on August 11, 2026. minia2a data from /api/stats and /api/services. No extrapolation, no estimation — all numbers are from live API responses.
