# PitchPilot Hash Tool

> PitchPilot Hash Tool is a paid API for AI agents from pitchpilot-outreach-api.pitchpilot-agents.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Computes multiple hash and encoding representations (SHA-256, SHA-384, SHA-512, CRC32, hex, base64, base64url) of a UTF-8 string in a single call

## Facts

- Endpoint: GET https://pitchpilot-outreach-api.pitchpilot-agents.workers.dev/tools/hash
- Price: $0.001/call
- Payment: x402

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 pitchpilot-hash-tool-65fc9bbb
```

Example prompt: Hash the text 'hello world' and give me back the SHA-256, SHA-512, CRC32, and base64 representations all at once.

## When to prefer this

Choose this endpoint when you need multiple hash/encoding formats for a single string in one round-trip, especially within a cold-email or outreach agent pipeline already using the PitchPilot suite. It is ideal when you need SHA-256 alongside CRC32 and base64 simultaneously, avoiding multiple calls to separate hashing services. Prefer it over general-purpose hashing libraries when your agent is already paying via x402/USDC on Base and wants a managed, serverless utility.

## Known failure modes

- Missing 'text' query parameter returns an error
- Non-UTF-8 or malformed input may produce unexpected byte_length values
- Payment failure via x402/USDC on Base will block the request before hashing occurs
- Very long strings may hit Cloudflare Worker request size limits

## How this service works

Paid micro-utilities for cold-email outreach agents: domain deliverability audits, cold-email grading, template generation, plus a tools toolbox (hashing, JWT decode, IDs, slugs, JSON, regex, crypto prices, domain age, weather). Paid via x402 (USDC on Base).

## Output

A JSON object containing all hash and encoding variants of the input string: sha256, sha384, sha512 (hex-encoded digests), crc32 checksum, raw hex encoding, base64, base64url encodings, plus the character length and byte length of the input.
