Sol-Incinerator Burn + Close API v2 Guide

A practical integration guide for Sol-Incinerator's HTTP API. The main user-facing outcomes are burning tokens, burning NFTs, and closing token accounts, while still supporting advanced batch cleanup and relay workflows.

Live API base URL: https://v2.api.sol-incinerator.com

Overview

Sol-Incinerator API v2 provides:

• Autonomous API key provisioning via POST /api-keys/generate
• Burn/close transaction building for SPL Token, Token-2022, and NFT account patterns
• Instruction-only endpoints when you want full client-side transaction assembly
• Preview/summary endpoints to estimate reclaimed rent and fees before execution
• Transaction relay endpoints to broadcast already-signed payloads
• Partner/referral monetization inputs with built-in validation

Core Endpoint Groups

Quick Start

1) Generate API key (no user input)

const baseUrl = 'https://v2.api.sol-incinerator.com';

const keyResp = await fetch(`${baseUrl}/api-keys/generate`, {
  method: 'POST',
  headers: { 'content-type': 'application/json' },
  body: JSON.stringify({ label: 'autonomous-agent' }),
});

if (!keyResp.ok) {
  throw new Error(`API key generation failed: ${keyResp.status}`);
}

const { apiKey } = await keyResp.json() as { apiKey: string };

2) Run preview-first flow

const headers = {
  'content-type': 'application/json',
  'x-api-key': apiKey,
};

const previewResp = await fetch(`${baseUrl}/burn/preview`, {
  method: 'POST',
  headers,
  body: JSON.stringify({
    userPublicKey,
    assetId,
    burnAmount: '1',
  }),
});

3) Build, sign, submit

1. Call /burn, /close, or /batch/close-all.
2. Decode base58 serialized transaction(s) and sign locally with the wallet keypair.
3. Submit through your wallet/RPC flow, or use /transactions/send and /transactions/send-batch.
4. Poll /transactions/status if needed.

Core Integration Rules

Auth

• Send API key in either:
  • x-api-key: ak_xxx.yyy (recommended for server agents)
  • Authorization: Bearer ak_xxx.yyy
• Core routes return 401 when key is missing or invalid.

Required body fields

• Single-asset routes (/burn, /close, previews, instructions):
  • userPublicKey
  • assetId
• Batch routes (/batch/close-all*):
  • userPublicKey

Optional body fields used often

• feePayer (public key)
• asLegacyTransaction (boolean)
• priorityFeeMicroLamports (integer)
• autoCloseTokenAccounts (boolean, burn flows)
• burnAmount (positive integer in atomic units; use string for large values)
• offset, limit (batch pagination/windowing)

Partner + referral validation

• partnerFeeAccount and partnerFeeBps are all-or-nothing.
• partnerFeeBps must be integer 0..9800.
• referralCode must be 2-20 lowercase alphanumeric.
• referralCode cannot be combined with partner fee fields.

Endpoint Selection

• Use /burn/preview or /close/preview before execution when:
  • the user needs fee visibility
  • assets may be frozen/invalid/non-empty
• Use /burn and /close when:
  • you want ready-to-sign transaction payloads
• Use /burn-instructions and /close-instructions when:
  • your app assembles transactions client-side
• Use /batch/close-all/preview first for wallet cleanup UX
• Use /batch/close-all/summary for lightweight dashboard counts
• Use /transactions/send-batch for multi-tx close-all pipelines

Example Workflow (Agent)

1. Generate an API key with POST /api-keys/generate.
2. Run preview endpoint for target operation.
3. If preview is acceptable, request executable transaction payload.
4. Sign transaction locally.
5. Submit signed payload.
6. Confirm completion via /transactions/status.
7. Store operation metadata (signature, fees, lamports reclaimed).

Guidelines

• DO run preview before destructive operations.
• DO pass burnAmount as a string for large atomic values.
• DO validate user/asset pubkeys before submitting.
• DO keep private keys local; only send signed transactions to relay endpoints.
• DON'T combine referralCode with partner fee fields.
• DON'T send unsigned payloads to relay routes.
• DON'T assume base64 encoding for relay payloads unless explicitly set encoding: "base64" (default is base58).

Resources

• Canonical docs (v2)
• OpenAPI spec (/openapi.json)
• LLM index (/llms.txt)
• Example flows (close account, burn token, burn NFT)
