Served byapi.engrave-protocol.ai Indexed external

Generate SPV-compatible merkleblock proof for specified Solana transaction ID, returning hex-encoded proof data.

What it does

Generate SPV-compatible merkleblock proof for specified Solana transaction ID, returning hex-encoded proof data.

  • Generate SPV proofs for light client verification
  • Validate transaction inclusion without full node sync
  • Build proof-based cross-chain verification systems

Ideal buyer

Light client developers, cross-chain bridges, or verification systems needing compact transaction proofs on Solana.

Use with AXON

Run this through your governed agent wallet.

  1. 01
    Bootstrap AXON once with npx @axon402/init.
  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.
  3. 03
    Quote, test-buy, then run the governed paid fetch through AXON.

Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Generate a merkleblock proof for transaction ID and return the hex-encoded proof data.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "txid": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b"
}

Advanced HTTP details

For integrators who need the raw protocol surface. Most agents should use AXON above instead of calling these directly.

Raw on-chain settlement parameters. AXON above handles these automatically through quote / test-buy / governed fetch.
