Endpoints

Endpoint	Returns
`GET /api/v1/tip`	Chain tip: height and hash.
`GET /api/v1/stats`	Network stats: height, difficulty, hashrate, 24h block interval, supply.
`GET /api/v1/blocks?limit=10`	Latest blocks, newest first. limit 1–100.
`GET /api/v1/block/height/{height}`	Block by height.
`GET /api/v1/block/{hash}`	Block by hash.
`GET /api/v1/block/{hash}/txs?limit=25&offset=0`	Transactions in a block. limit 1–100.
`GET /api/v1/tx/{txid}`	Transaction with inputs (incl. prevouts), outputs, fee and status.
`POST /api/v1/tx`	Broadcast a signed transaction: raw hex as the request body. Returns {"txid": ...}. Limited to a few per minute per IP.
`GET /api/v1/address/{address}`	Address summary: funded/spent totals and tx counts.
`GET /api/v1/address/{address}/txs`	Recent transactions for an address.
`GET /api/v1/address/{address}/utxo`	Unspent outputs for an address.
`GET /api/v1/richlist?limit=100&offset=0`	Top addresses by balance. limit 1–1000.
`GET /api/v1/mempool`	Mempool summary.
`GET /api/v1/mempool/txs?limit=25`	Recent mempool transactions. limit 1–100.
`GET /api/v1/fees/recommended`	Recommended fee rates.
`GET /api/v1/supply/total`	Total supply in TRMP as a plain number (text/plain). Equals circulating supply; not max supply.

Amounts are integers in satoshis (1 TRMP = 100,000,000 sats). Some very large sums are returned as strings so they stay exact.
Rate limit: 120 requests per minute per IP (bursts up to 60); broadcasts 6 per minute. Over the limit you get 429 with a Retry-After header.
Errors are JSON: {"error": "..."} with status 400, 404, 429 or 503. A rejected broadcast returns 400 with the node's reason.
CORS is open, so you can call it from any website.
Supply endpoints return a bare number as text/plain for supply trackers.
