Delx Hash
x402
Delx Hash is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-20).
Hashes a text string using SHA-256, SHA-1, or MD5 and returns a compact deterministic receipt for $0.001 USDC per call.

How this service works
SHA-256 hash API for agents: hash text with SHA-256, SHA-1, or MD5 for $0.001 USDC and return a compact deterministic receipt—not a password KDF. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns a JSON object containing the computed hash digest string, the algorithm used (SHA-256, SHA-1, or MD5), the length of the original input, and a compact deterministic receipt confirming the computation.
Example use cases
Deduplication fingerprint for ingestion pipeline
“Hash the string 'user_session_abc123_2026-01-15' with SHA-256 so I can use it as a deduplication key before inserting into the database.”
MD5 checksum for legacy system compatibility
“I need an MD5 digest of the string 'invoice-2026-00482' to match what our legacy system expects for record lookup.”
Data integrity receipt for audit log
“Compute a SHA-256 hash of this JSON blob — '{"orderId":"ORD-9921","amount":49.99}' — and give me the deterministic receipt I can store in our audit log.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/hash?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a quick, paid, receipted hashing call without managing local crypto libraries — especially useful in x402-native agent workflows where auditability and a deterministic receipt matter. Prefer it over rolling your own hash when you need a verifiable, third-party-attested digest. Not suitable as a password key-derivation function (KDF); use bcrypt/argon2 for passwords instead.
Side effects
- Empty or missing input text returns a validation error
- Unsupported algorithm name returns a 400 bad request
- Payload exceeding size limits returns an error
- Payment failure or insufficient USDC balance returns a 402 response
- Network timeout returns a 5xx error
