# AgentBIT SHA-256 Hash

> AgentBIT SHA-256 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 the SHA-256 cryptographic hash of any input string, returning the hex digest

## Facts

- Endpoint: POST https://agentbit.app/v1/hash/sha256
- 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-256-hash-29cc6834

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-256-hash-29cc6834 -d '<json body>'
```

Example prompt: Can you compute the SHA-256 hash of the string 'Hello, World!' for me?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call SHA-256 hash computation without setting up any API keys or accounts — ideal for AI agents that occasionally need to hash strings as part of a workflow (integrity checks, cache keys, fingerprinting) and want to avoid bundling a crypto library or managing infrastructure. Not suitable for bulk hashing of large volumes of data where a local implementation would be more efficient.

## Known failure modes

- Missing or empty input field returns a validation error
- Non-string or malformed JSON body may return a 400 bad request
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 results in a 402 Payment Required response, blocking the computation

## 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

Returns a JSON object containing the SHA-256 hex digest of the submitted input string — a 64-character lowercase hexadecimal string representing the deterministic cryptographic hash.
