Changelog

v0.1.1: live playground, usage ledger, agent discovery

• Persistent usage ledger with lifetime counters, published on /healthz and a token-protected /stats.
• CORS enabled on the endpoint, so the playground and status page now call production live from the browser.
• Agent discovery surface: llms.txt, robots.txt, a sitemap, and an OpenAPI document with a servers block.
• Free-tier hardening: spoofed-IP fix, batch-request guard, and free calls refunded on server-fault errors.
• Paid-call settlement is now cancelled when a call errors — buyers never pay for failures.

base-tx-explain v0.1.0

Our first tool is live: deterministic Base transaction decoding for AI agents. One MCP tool, explain_transaction(tx_hash), returns a strict JSON explanation of any Base mainnet transaction — same input, same output, no LLM in the response path.

• Base mainnet transaction decoding across ~40 builtin event formats — ERC-20/721/1155, Uniswap V2/V3/V4, Seaport, Aave V3, OP-stack bridges, ERC-4337, EAS, and more.
• MCP streamable-HTTP endpoint at base-tx-explain.fly.dev/mcp.
• x402 pay-per-call support — $0.02 in USDC on Base, 10 free calls per client.
• Risk flags backed by Sourcify verification and public drainer blocklists.
• Listed in the official MCP registry as io.github.0200project/base-tx-explain.
• Validated against 100 random live Base transactions before release — 95 decoded to a specific action type, zero crashes.
