# Numora Fibonacci Number Generator

> Numora Fibonacci Number Generator is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Computes the nth Fibonacci number given an integer index n

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/number/fibonacci
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-fibonacci-number-generator-de93fd05
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_V9USFcSq1PmCV5Krje8j2

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-fibonacci-number-generator-de93fd05 -d '<json body>'
```

Example prompt: What is the Fibonacci number at index 42? Use a pure math computation API with no external dependencies.

## When to prefer this

Use this endpoint when you need a precise, server-side Fibonacci computation without writing your own code, especially inside an agent pipeline that already uses x402 micropayments on Base. Prefer it over client-side calculations when auditability or consistent server-side math is required.

## Known failure modes

- Missing required parameter n returns a validation error
- Non-integer value for n may cause a schema error
- Extremely large n values may cause overflow or timeout
- Payment failure via x402 micropayment returns 402 status before computation begins

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a boolean success field, a result object containing the computed Fibonacci number for the given index n, and a human-readable computation string describing what was calculated.
