Show HN: A DeFi data API where AI agents pay per call via HTTP 402 micropayments

Hacker News - Mon, 02/23/2026 - 6:44pm

HTTP 402 Payment Required has been in the spec since 1997, “reserved for future use.” Turns out the future is AI agents that need to pay for API calls without signing up for anything.

I built a DeFi/crypto data API that uses the x402 protocol (by Coinbase) to handle payment natively in the HTTP layer. No API keys, no subscriptions, no accounts. An agent sends a request, gets back a 402 with payment details, pays in USDC on Base, and retries — all in one flow.

How it works:

1. Client calls an endpoint 2. Server returns 402 with payment instructions (x402) 3. Client signs a USDC payment (0.001–0.008 USDC per call) and retries with a payment proof header 4. Server verifies payment and returns the data

The x402 facilitator (middleware) handles verification, so the server just defines prices and serves data.

8 endpoints currently live: token prices, gas tracker, DEX swap quotes, token security scanner, whale tracker, DeFi yield scanner, funding rates, and wallet profiler. Each call costs fractions of a cent (1,000 lookups/day is roughly $1–5).

Built with Express.js. The server is registered as ERC-8004 Agent #18763 on Base mainnet. The whole thing is ~500 lines of code — most of the complexity lives in the x402 facilitator library.

Ransomware attacks on manufacturers are skyrocketing. For cybercriminals, the sector sits at a sweet spot on the risk-reward continuum.

Show HN: Using LLMs and differential testing to convert code

Hacker News - Mon, 02/23/2026 - 6:03pm

This is the second part of a post aligned with a talk I gave recently at the Sydney Rust meetup.

I have found significant success in this process converting decompiled code and also converting source code from python to go. Give an LLM a target and they can be extremely stubborn (in a good way).

Show HN: Boardroom MCP - Multi-advisor governance engine for AI agents

Hacker News - Mon, 02/23/2026 - 5:55pm

Hey HN,

I noticed a recurring issue when building autonomous agents: they're great at execution but terrible at nuanced judgment. When faced with ambiguity, they just hallucinate the most statistically probable path without considering second-order effects.

Instead of trying to fix this with massive system prompts, I built an MCP (Model Context Protocol) server that offloads decisions to a multi-advisor "boardroom."

How it works: 1. Agent encounters a decision -> calls the `analyze()` MCP tool. 2. Server routes the query to relevant advisors (from 38 domains, 450+ profiles). 3. Advisors debate. This is the core mechanic: if advisors agree too quickly, the system flags it. Tension is mandatory. 4. The server synthesizes the debate, logs it to a persistent LEDGER (so the agent has institutional memory), and returns a risk-scored recommendation.

I built this locally so there's zero cloud dependency and your agent data stays yours. It works natively with Claude Desktop, Claude Code, Cursor, Windsurf, or any MCP client.

You can checkout the core engine here: https://github.com/randysalars/boardroom-mcp If you want to read the docs: https://salars.net/boardroom/docs

Would love to know if anyone else has experimented with structured multi-agent debate vs LLM-as-a-judge patterns.
