How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

A JSON object with 'ok' (boolean, true on success) and 'paid' (boolean, confirming USDC micropayment was processed), along with the computed Fibonacci number at the requested index.

Example use cases

Fibonacci index lookup for algorithm

“I need to know the exact Fibonacci number at position 78 for a coding problem I'm working on — can you look it up?”

Math tutoring Fibonacci verification

“My student claims the 20th Fibonacci number is 6765 — can you verify that by computing fib(20) from the toolbox?”

Agent pipeline numeric seed generation

“Generate the Fibonacci number at index 13 so I can use it as a deterministic seed value in my workflow.”

Endpoint

When to prefer

Choose this endpoint when you need a trustless, no-signup, pay-per-call Fibonacci computation billed in USDC micropayments via x402 — ideal for AI agents that cannot hold API keys but can authorize crypto micropayments, or when auditability of payment-as-identity is required.

Side effects

Missing or invalid index parameter returns an error response
Non-integer or negative index may produce undefined behavior or error
Payment failure (insufficient USDC balance) results in 402 response and no computation
Network timeout on Cloudflare Worker edge node
