Proposal: x402 market-signal + decision-attestation endpoints for polymarket-agent

What this adds to polymarket-agent

Two machine-payable endpoints that let any autonomous trading agent consume market intelligence and publish verifiable decision attestations — no API key, no subscription, pay-per-call with USDC on Base:

Endpoint	Method	Price	Purpose
/api/market/signal	GET	$0.010 USDC	Real-time market signal with sentiment, volatility score, and derived edge summary
/api/agent/attest	POST	$0.040 USDC	EIP-712 signed attestation anchoring agent reasoning to an on-chain-verifiable record

How it works

Payments use the x402 HTTP payment protocol — the agent includes a X-PAYMENT header with a Base USDC micropayment; the gateway verifies on-chain settlement before serving the response. No accounts, no OAuth, no rate-limit tiers.

Public transparency

• Live ledger of all settlements: enclave402.com/api/ledger
• OpenAPI spec: enclave402.com/openapi.json
• Source: gitlab.com/yourstruly-oliver/x402-autonomous-api

Integration path

A polymarket-agent integration would:

1. Call /api/market/signal before placing a trade to get an independent signal overlay
2. Call /api/agent/attest after a decision to create a verifiable audit trail
3. Both calls are stateless — no session, no signup, just HTTP + x402 payment header

Happy to open a PR with a reference integration if there is interest. The endpoints are live now at enclave402.com.
