Guides for AI-agent builders
Two tracks: deterministic finance & quant math your agents can call over x402, and the safety practices that keep autonomous agents from doing damage.
Finance & quant guides
How AI agents pay for and call deterministic finance & quant endpoints over x402 — DCF & IRR, Black-Scholes Greeks, LP/GP waterfalls, bond analytics, and the x402 protocol itself.
What is x402? The complete guide to the agent-payment protocol
x402 lets AI agents pay for APIs per request using HTTP 402 and USDC settlement. How it works end to end — written by a team running x402 in production, with a live challenge you can reproduce.
x402 and MCP: paid tools for AI agents
How MCP (tool discovery) and x402 (per-call payment) compose so AI agents can find and pay for tools — no API key or subscription.
Black-Scholes pricing and the Greeks for AI agents
Black-Scholes pricing and the full Greek set (delta, gamma, vega, theta, rho) for AI agents — deterministic, pay-per-call OptionLens API over x402 at $0.30 per request.
Bond yield, duration, and amortization for AI agents
Bond yield-to-maturity, price, duration, convexity, and loan amortization for AI agents — BondLens deterministic pay-per-call API at $0.25 per request over x402.
DCF and IRR for AI agents: a pay-per-call cashflow API
DCF, NPV, IRR, XIRR, MOIC, DPI, TVPI, and payback in one deterministic pay-per-call API for AI agents. CashflowLens runs the solver — no LLM hallucination on the numbers.
Deterministic finance math for AI agents (why LLMs shouldn't compute an IRR)
Why LLMs shouldn't compute IRR, Black-Scholes, or waterfall math — and how deterministic, audited finance APIs let AI agents return numbers they can defend to a risk desk.
How AI agents pay for APIs with x402
How AI agents pay for APIs over x402 — HTTP 402 challenges, USDC-on-Base settlement, the Bazaar discovery index, and how to wire payment into a Cursor or Claude Code agent.
LP/GP distribution waterfalls for AI agents
LP/GP distribution waterfalls for AI agents — return of capital, preferred return, GP catch-up, carry split. WaterfallLens deterministic API at $0.30 per call over x402.
Agent safety guides
Securing agent workflows: auditing risky operations, blocking destructive commands, and running blameless incident response after failures.
Signed receipts for AI agent actions: the attestation loop
Give every x402 payment and MCP tool call your agent makes a tamper-evident, third-party-verifiable receipt — one $0.05 attestation per action, free verification, no account required.
Validate your AI agent's contact list in 5 lines
A copy-paste loop for AI agents: deterministic email validation and normalization over a whole contact list — free API key, no crypto wallet, the same verdict on every run.

Turn this research into production usage
Cluster pages map intent. Route builders from here into endpoint calls, pricing, and integration docs so discoverability can compound into MRR.
