# pastable-x402 Text Hashing

> pastable-x402 Text Hashing is a paid API for AI agents from pastable-x402.pages.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Hashes an input string using MD5, SHA-256, and SHA-512 simultaneously, returning all three digests plus byte length.

## Facts

- Endpoint: GET https://pastable-x402.pages.dev/text/hash
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/pastable-x402-text-hashing-1f985cca

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 pastable-x402-text-hashing-1f985cca
```

Example prompt: Can you hash the string 'hello' using UTF-8 encoding and give me the MD5, SHA-256, and SHA-512 digests?

## When to prefer this

Choose this endpoint when you need multiple hash algorithms (MD5, SHA-256, SHA-512) computed simultaneously in a single paid call, saving round-trips compared to separate hashing APIs. Ideal for agents that need to fingerprint, deduplicate, or verify text content and want all common digest formats at once. The x402 micropayment model ($0.02 USDC) makes it suitable for per-operation billing in automated pipelines without subscriptions.

## Known failure modes

- Missing required query parameters 'data' or 'encoding' returns an error
- Invalid encoding value (not utf8, base64, or hex) causes a bad request
- Payment not completed via x402/Base mainnet results in 402 Payment Required
- Malformed base64 or hex input string causes a processing error
- Network timeout on the Cloudflare Pages edge function

## How this service works

Pay-per-call utility APIs for agents: EVM helpers (checksum, unit conversion, keccak), data transforms (CSV to JSON, JSON diff, URL canonicalisation), text tools (hashing, JWT decode), and Bazaar market intelligence. x402 on Base mainnet.

## Output

Returns a JSON object containing the MD5, SHA-256, and SHA-512 hex-encoded digests of the input string, plus the byte length of the input. All three hash algorithms are computed in a single call.
