TronZap Wallet Orders API
Fully public, unauthenticated Orders API for non-custodial wallet integrations. Four operations — POST /v1/orders/calculate (a true dry run whose total is guaranteed to equal the order amount), POST /v1/orders (returns a deposit address, an exact TRX amount and a ttl, typically 3600s), POST /v1/orders/check and POST /v1/orders/cancel. The provider states "No authentication headers are required. The Orders API is fully public"; only Content-Type and Accept are needed, and an optional referral_code carries partner commission. It is the only TronZap surface with a documented rate limit (1 request/second/IP, HTTP 429, no Retry-After — observed live 2026-08-30) and the only one with a documented reversal path (cancel while the order is still in `new` status). Orders move through new, paid, processing, completed, failed, cancelled, expired. Documented at docs-wallets.tronzap.com; no SDK covers it and llms.txt does not mention it. No OpenAPI.
