SHA-256 Hash Computation API
x402
SHA-256 Hash Computation API is a paid API for AI agents from x402-canary.nicolas-x402-16f380a7.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).
Computes a SHA-256 cryptographic hash digest of an input text string and returns the hex digest along with algorithm metadata.

How this service works
Free need-to-tool routing plus pay-per-call npm docs and TypeScript API signatures, npm breaking-change diffs, JavaScript-rendered browser snapshots and deterministic coding-agent checks via AgentCash/x402.
Output
Returns a JSON object with a `data` field containing the `digest` (hex-encoded SHA-256 hash string) and `algorithm` (always 'sha256'), plus a `meta` field with `engine` set to 'hash'.
Example use cases
Deduplication fingerprint for log entries
“Hash this log line so I can deduplicate it in my pipeline: 'ERROR 2024-01-15T12:34:56Z service=auth msg=token_expired user=42'”
Content integrity check before storing
“Give me the SHA-256 checksum of this config value so I can verify it hasn't changed later: 'db_host=prod.db.internal port=5432 pool=10'”
Deterministic ID generation from text
“I need a deterministic unique ID for the string 'user:alice@example.com:session:2024' — can you SHA-256 hash it?”

Endpoint
POSThttps://x402-canary.nicolas-x402-16f380a7.workers.dev/v1/hash/sha256When to prefer
Choose this endpoint when you need a quick, pay-per-call SHA-256 hash of a text string without setting up any local crypto library, or when operating inside an agent/workflow that already uses the x402 micropayment protocol for tool calls. It is ideal for coding agents that need deterministic checksums as part of a larger pipeline.
Side effects
- Input text exceeds 262,144 character limit — request rejected
- Missing or malformed request body — likely 400 error
- Payment not provided or insufficient — 402 Payment Required response via x402 protocol
- Service unavailable on Cloudflare Workers edge — 5xx error
