Use-case recipes for EVM agent builders
The goal is not “more simulation in theory”. The goal is matching the real blind-send pain in the exact workflow where a builder feels it.
The recommended first trust surface before any paid flow is /first-unpaid-402.
If the builder needs one canonical page that chooses between recipes, examples, and integrations, use /start-here.
Root host to live API path
Start on https://nishvault.com for trust context, use https://nishvault.com/go/recipes for the measurable bridge, then verify discovery at https://api.nishvault.com/.well-known/x402 before the first unpaid 402.
Trading bot revert-risk guard
- One paid preflight before the bot broadcasts a swap.
- Inspect revert risk and gas context before commit.
MCP or tool-calling agent send guard
- Put one paid preflight between “agent decided” and “wallet broadcast”.
- Keep a clean artifact trail for why the send happened.
Treasury or queue worker guard
- Drain queued jobs only after one paid preflight per transaction shape.
- Block blind sends before the worker spends more onchain.
