Bounty Engineer Cache Key Plan
x402
Bounty Engineer Cache Key Plan is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Computes a canonical, deterministic cache key (SHA-256) for an HTTP request by normalizing its URL, body, method, and headers, optionally dropping specified parameters.

How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a JSON object with ok=true, mode='cache_key_plan', a sha256: prefixed cache key string, and a canonical sub-object containing the normalized URL, body, method, and headers used to derive the hash.
Example use cases
Deduplicating agent API calls
“Before I fire off that POST to the pricing API again, compute the cache key for the request with URL https://api.prices.com/v2/quote, method POST, and body {"asset":"BTC","qty":10} so I can check if I already have a cached result.”
Stripping volatile params before caching
“I need the canonical cache key for a GET request to https://data.example.com/feed?ts=1718000000&page=1 — but drop the 'ts' timestamp parameter so the key stays stable across refreshes.”
Fingerprinting requests in a retry workflow
“Generate the SHA-256 cache key for this failed API request so my retry planner can track it: POST to https://api.exchange.com/order with headers {"content-type":"application/json"} and body {"side":"buy","amount":500}.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/cache-key-plan?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent needs a deterministic, reproducible fingerprint for an HTTP request — especially before deciding to make a live (paid) API call or serve from cache. It is ideal when you need to normalize requests that may have minor variations (extra headers, volatile timestamps) into a stable key. Prefer it over ad-hoc hashing logic when you want consistent canonicalization rules and SHA-256 output compatible with a broader Bounty Engineer caching/routing pipeline.
Side effects
- Missing or malformed URL field returns a validation error
- Invalid JSON body causes parsing failure
- Unsupported HTTP method may result in an error or unexpected normalization
- Network timeout to the Render-hosted service if the instance is cold-starting
- drop_params referencing non-existent parameters silently ignored (no error, but key may not match expectations)
