# Swift Bot Labs Toolbox – Hash

> Swift Bot Labs Toolbox – Hash is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-31).

Computes one or all cryptographic hash digests (MD5 through BLAKE3/Keccak256) for a given data string, with configurable input and output encodings.

## Facts

- Endpoint: POST https://x402-toolbox.swiftbotlab.workers.dev/v1/hash?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/swift-bot-labs-toolbox-hash-43c41a10
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_I0Vb-XnfxAKrcoI_j6NzS

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 swift-bot-labs-toolbox-hash-43c41a10 -d '<json body>'
```

Example prompt: Hash the UTF-8 string 'hello' using all available algorithms and give me the results in hex — I want sha256, keccak256, and everything else at once.

## When to prefer this

Choose this endpoint when you need cryptographic hashes without setting up a server-side library, especially for blockchain-adjacent workflows (keccak256, ripemd160) or when you need all common algorithms in one call. The pay-per-call x402 model means no account setup is required, making it ideal for sporadic or automated agent workflows. Prefer it over general-purpose compute endpoints when you specifically need deterministic, well-specified hash outputs with encoding flexibility.

## Known failure modes

- Input data exceeds 1 MB maxLength limit — request rejected
- Unsupported algorithm or encoding enum value — validation error
- Malformed base64 or hex input when inputEncoding is set accordingly — decoding error
- Payment not provided or insufficient USDC — 402 Payment Required response
- Empty data field — may return zero-byte hashes or validation error

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

Returns a JSON object with ok:true, the tool name 'hash', and a result object containing the byte length of the input and a 'hashes' map of algorithm names to their digest strings. When algorithm is 'all', every supported algorithm is included in the map.
