How this service works
Real-time Bitcoin fee forecast: next-block, 30-min, 1-hr with congestion tier
Output
Returns a JSON object containing fee rate estimates (in sat/vB or similar unit) for next-block, 30-minute, and 1-hour confirmation targets, a congestion tier enum ('low', 'medium', 'high', or 'critical'), example cost breakdowns, and timing metadata reflecting current mempool conditions.
Example use cases

Technical details
Endpoint
GEThttps://tinkrr-api.tinkrr.workers.dev/btc/feesWhen to prefer
Choose this endpoint when you need a quick, structured Bitcoin fee forecast with explicit congestion classification and multi-window estimates (next-block, 30-min, 1-hr) in a single call. Prefer it over raw mempool explorers when you need a clean API with congestion tier labels suitable for automated decision-making in wallets, payment processors, or DeFi tooling.
Side effects
- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Upstream mempool data unavailable — returns 503 or stale data
- Rate limit exceeded — returns 429 Too Many Requests
- Malformed request — returns 400 Bad Request
