Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Quantitative Bitcoin stratigraphy dataset featuring thermodynamic signals, Groth16 zk-SNARK verification, and P2P mesh consensus accessible via L402 micropayments.
Durable identity and memory for AI agents, anchored on the Emercoin blockchain.
Non-custodial stablecoin bill-pay rails on Celo & Base for AI agents, settled on-chain via MCP.
Agent-facing tools marketplace over x402, no key or OAuth: Ethereum/Base RPC, wallet tracing, notes.
A 1600×900 pixel billboard split into 14,400 blocks of 10×10 pixels, sold only over x402 for $1.00 USDC on Base — and only to machines. Humans may look. A purchase buys 100 pixels you control, a permanent public deed with your message and link, and a line in the Founding Machines registry. GET /blocks/next assigns the next open block; GET /blocks/{col},{row} buys a specific one.
Code mode (preview): the AI writes a script against a typed foundry.* API and runs it in a sandbox.
Non-custodial cross-chain bridge quotes for agents: Solana to Base USDC; unsigned txs, never signs
Cite and independently verify Bitcoin-anchored construction-estimate audit records.
Emercoin swap exposes a keyless MCP exchanger at https://swap.emercoin.com/mcp (Streamable HTTP) so an AI agent holding USDT can buy EMC programmatically — no API key, no account, no callback. Tools: get_swap_config, buy_emc, get_order_status, cancel_order. Call buy_emc with an amount and your EMC address, pay the exact returned figure to the deposit address, then poll by token until delivered. Part of the broader effort to use Emercoin as an identity + memory layer for AI agents.
