Request cross-chain proof generation or query proof status using job-based asynchronous processing with payment proof support.

What it does

Request cross-chain proof generation or query proof status using job-based asynchronous processing with payment proof support.

  • Generate proofs for cross-chain message verification
  • Request payment proofs for settlement confirmation
  • Query proof status for asynchronous job tracking
  • Verify state transitions across connected chains

Ideal buyer

Cross-chain application developers and bridge operators needing programmatic proof generation and verification.

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 proof for this cross-chain transfer and return the job ID for status tracking.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "proof_request": {
    "message_hash": "0x...",
    "source_chain": "base",
    "target_chain": "ethereum"
  }
}

Advanced HTTP details

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

curl fallback

curl https://auth.api.polymer.zone/proof-api \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"proof_request":{"message_hash":"0x...","source_chain":"base","target_chain":"ethereum"}}'

Payment & settlement details

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