# AgentBIT SHA-512 Hash

> AgentBIT SHA-512 Hash is a paid API for AI agents from agentbit.app, paid per call via x402, $0.0015/call, status unknown (last checked 2026-09-13).

Computes a SHA-512 cryptographic hash of any input string

## Facts

- Endpoint: POST https://agentbit.app/v1/hash/sha512
- Price: $0.0015/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentbit-sha-512-hash-8c33950e
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Au2VrVRXsOcF07dRN_pi-

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 agentbit-sha-512-hash-8c33950e -d '<json body>'
```

Example prompt: What's the SHA-512 hash of the string 'Hello, World!'?

## When to prefer this

Choose this endpoint when you need a serverless, pay-per-call SHA-512 hash with no API key setup — ideal for agents that infrequently need hashing and want to avoid managing credentials. Prefer standard library functions for high-volume or latency-critical hashing.

## Known failure modes

- Missing or empty 'input' field returns a validation error
- Non-string input types may cause a 400 bad request
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 prevents the call from executing

## How this service works

Live web, business, finance and security tools for AI agents. Pay per call with x402 — no signup, no API keys.

## Output

A JSON object containing the SHA-512 hex digest of the submitted input string — a 128-character lowercase hexadecimal string representing the 512-bit hash.
