How this service works
A $5 evidence-first check that tells developers and AI agents whether a bounty can actually pay before they build.
Output
A JSON object containing the current ETH/USD exchange rate, Base mainnet gas price in Gwei, the latest Base block number, and a list of data source URLs used (e.g. Coinbase exchange rates API and Base mainnet RPC).
Example use cases
Pre-work bounty viability check
“I found a bug bounty paying 0.5 ETH — can you use BountySignal to pull the current ETH/USD rate and Base gas prices so I can figure out if the net payout is actually worth my time before I start?”
AI agent pre-flight before on-chain submission
“Before my agent submits a solution to this on-chain bounty, run a BountySignal market pulse check to confirm the current ETH price and gas costs on Base so we know the reward still covers the work.”
Real-time Base network cost snapshot
“What are the gas prices on Base mainnet right now, and what's ETH trading at in USD? I want the latest block number too so I know the data is fresh — grab it from BountySignal.”
Technical details
Endpoint
POSThttps://bountysignal-radar-v2.minhtuan36zzz97948.chatgpt.site/api/x402/market-pulse?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.01) real-time snapshot of ETH/USD price, Base gas costs, and block height specifically to evaluate bounty economic viability before committing effort. Prefer it over general price APIs when you want a bundled signal combining price + gas + chain state in one call, especially in agentic workflows that auto-assess on-chain bounties.
Side effects
- Upstream data source unavailable (Coinbase API or Base RPC down) — may return stale or missing price data
- Payment not processed — endpoint requires $0.01 USDC via x402 protocol; unpaid requests are rejected
- Malformed input object — schema requires both 'input' and 'output' fields in the request body
- Rate limiting or provider throttling — high-frequency requests may fail if underlying RPCs are congested
