How this service works
Hash and unit utilities for AI agents: SHA-256, SHA-1, HMAC-SHA256, stable JSON fingerprint, ETH/Gwei/Wei conversion, human bytes, and duration parsing. Pay-per-request USDC via x402. No API keys, no accounts.
Output
Returns a JSON object with ok: true and a stable SHA-256 fingerprint string derived from the canonicalized (key-sorted) representation of the input JSON body, ensuring identical hashes for semantically equivalent objects regardless of key ordering.
Example use cases
Deduplicating agent memory records
“I'm storing observations from my AI agent and need to detect duplicates — can you fingerprint this JSON observation so I can compare it against previously seen ones? The object is {"event": "page_view", "url": "https://example.com", "user_id": "u123"}.”
Cache key generation for API responses
“I want to cache API responses by content — can you give me a stable fingerprint for this response object so the cache key doesn't break when keys come back in a different order? Object: {"status": "ok", "count": 5, "items": ["a", "b"]}.”
Config change detection in CI pipeline
“Can you fingerprint this deployment config JSON so I can tell if anything actually changed between two pipeline runs, even if the keys got shuffled? Config: {"region": "us-east-1", "replicas": 3, "image": "myapp:latest"}.”
Technical details
Endpoint
POSThttps://agent-forge.annushka1190.workers.dev/v1/fingerprintWhen to prefer
Choose this endpoint when you need a deterministic, key-order-independent hash of a JSON object — particularly useful for deduplication, content-addressable storage, cache key generation, or change detection where key ordering may vary. Prefer this over raw SHA-256 hashing when your input is a JSON object and you need canonical stability. Requires no API key; pay-per-use via USDC x402.
Side effects
- Missing required 'input' field returns a validation error
- Non-JSON body type or mismatched method returns a schema error
- Payment failure via x402 results in 402 Payment Required response
- Malformed or unparseable JSON body may return a 400 error
- Extremely large JSON objects may hit Cloudflare Worker size or CPU limits
