x402
SHA-256 Base64 Digest (agentshelf.syntexa.ch) is a paid API for AI agents from agentshelf.syntexa.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-01).
Computes a SHA-256 cryptographic hash of input text and returns the digest encoded as a Base64 string, with no network calls or LLM involvement.

How this service works
Call when an agent needs a sha256 digest of text, encoded as base64. No network and no LLM. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/digest-sha256-base64 first.
Output
A SHA-256 hash of the provided text, returned as a Base64-encoded string. The output is deterministic and repeatable for the same input. No additional metadata or network activity is involved.
Example use cases
Content deduplication key generation
“Hash this product description with SHA-256 and give me the base64 digest so I can use it as a deduplication key: 'Premium wireless headphones with 40-hour battery life and active noise cancellation.'”
Data integrity fingerprinting
“I need to create a SHA-256 base64 fingerprint of this JSON payload before storing it: '{"userId":"abc123","amount":49.99,"currency":"USD"}' — can you generate that hash?”
Password or token derivation check
“Take the string 'my-secret-api-key-v2' and compute its SHA-256 hash encoded as base64 so I can compare it against a stored reference value.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/digest-sha256-base64?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a SHA-256 hash specifically encoded as Base64 (rather than hex) and want a guaranteed offline, deterministic computation with no LLM or external network involvement. Prefer this over building your own hashing if you need a simple pay-per-use cryptographic primitive in an agent workflow. Use the free sandbox endpoint (POST /v1/sandbox/digest-sha256-base64) first to validate your integration before incurring the $0.01 USDC cost.
Side effects
- Empty or missing 'text' field returns a validation error
- Text exceeding 100,000 characters is rejected
- Invalid or missing payment (x402) results in a 402 Payment Required error
- Malformed request body returns a 400 error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| key | string | HMAC secret. Required on HMAC SKUs. Omit it for plain digests and checksums. The key is not stored. |
| text | string | Message to digest. For raw-hex SKUs this is hex bytes; for utf16 or latin1 SKUs it is decoded with that encoding. Otherwise it is UTF-8 text. |
