# Taifoon mcp.digest

> Taifoon mcp.digest is a paid API for AI agents from www.taifoon.io, paid per call via x402, $0.005606/call, status unknown (last checked 2026-10-17).

Computes a cryptographic digest (SHA-256 or Keccak-256) of a given UTF-8 text string via a paid, verified multi-seller coordination layer

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 taifoon-mcp-digest-32ab161f -d '<json body>'
```

Example prompt: Can you compute the SHA-256 digest of this text: 'Hello, world! This is my important document.' — using Taifoon's verified hashing service?

## When to prefer this

Choose this endpoint when you need a trustless, verifiably correct cryptographic hash of a UTF-8 string and are willing to pay a micro-fee per call. Especially useful in blockchain or Web3 contexts where keccak256 is required, or when you want a third-party-verified sha256 digest rather than a locally computed one. Prefer it over local hashing when auditability, seller accountability, and on-chain provability matter.

## Known failure modes

- Invalid algorithm value (not sha256 or keccak256) causes input rejection
- Non-UTF-8 text input may cause encoding errors
- Payment failure via x402 protocol blocks the request
- No available seller behind the coordination wall returns an error
- Answer verification failure means the call returns an error and is not charged

## How this service works

mcp.digest, sold by Taifoon: 2 sellers behind this wall, the best-ranked one answers; code checks the answer before you are charged (a failed answer is not charged), Jev grades it after. Price 0.006553 USDC.

## Output

Returns the cryptographic digest (hash) of the provided UTF-8 text using the specified algorithm (sha256 or keccak256). The response is verified by code before the caller is charged; failed or incorrect answers are not billed. A grader (Jev) provides post-hoc quality grading of the answering seller.
