How this service works
CuseTheJuice agent APIs on Base USDC: email relay, spam and phishing checks, IP threat scoring, Base Notary hash anchors, and Jupiter Solana swap quotes. Hash anchor (create): flat $0.1 per request. SHA-256 stored in Base tx calldata (sizeBytes required for POST upload). Pay with x402 (Base USDC). HTTP shape: extensions.bazaar on the 402. Catalog: https://app.cusethejuice.com/agents
Output
Returns a Base blockchain transaction ID and confirmation that the SHA-256 hash has been stored in the transaction's calldata, providing a permanent, publicly verifiable on-chain anchor record. The agent receives proof of the anchoring event including the transaction reference.
Example use cases
Example prompt
“Anchor this SHA-256 hash to the Base blockchain so I have a tamper-proof on-chain record — the hash is e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 and the original file size is 204800 bytes.”
Technical details
Endpoint
POSThttps://app.cusethejuice.com/api/bots/hash-anchor/createWhen to prefer
Use this endpoint when you need to create a verifiable, immutable on-chain record that a specific file existed and had a specific SHA-256 hash at a point in time — ideal for document notarization, audit trails, intellectual property timestamping, or compliance proofs. Prefer this over centralized timestamping services when tamper-proof blockchain proof is required. Pair with the sibling hash-anchor/verify endpoint to later confirm the anchor.
Side effects
- Missing or invalid SHA-256 hash input — returns 400 bad request
- sizeBytes parameter not provided for POST upload — returns 400 bad request
- Insufficient USDC balance or failed x402 payment — returns 402 payment required
- Base network congestion causing delayed or failed transaction submission
- Invalid x402 payment extension format — returns 402 with extensions.bazaar details
- Rate limiting or service downtime — returns 503
