# Pacta (by Fractal Neurons)

> Free pre-execution contract and governance safety API for AI agents (launch: $0, no API key, no wallet), plus block-pinned DeFi control-plane snapshots and timelock alerts. 14 Sprints · 37 Indexed Records.

Pacta checks who can change the rules of DeFi protocols (proxy admins, timelock delays, Safe quorums, roles) and compares that with what the protocols document. Every record is a read-only on-chain observation pinned to an Ethereum Mainnet block number and canonical block hash.

## Free API for agents (launch: $0, no API key, no wallet)
- Remote MCP (Streamable HTTP, zero install): https://pacta-x402.pacta.workers.dev/mcp · Claude Code: `claude mcp add --transport http pacta https://pacta-x402.pacta.workers.dev/mcp` · Cursor: `{"mcpServers": {"pacta": {"url": "https://pacta-x402.pacta.workers.dev/mcp"}}}`. Tools: pacta_check_preflight, pacta_scan_control_plane, pacta_scan_timelock_op, pacta_scan_proposal_diff, pacta_get_live_timelocks (all read-only).
- One call: `curl -s "https://pacta-x402.pacta.workers.dev/v1/check/preflight?chain=ethereum&address=0x..."` returns a verdict (IMMUTABLE_NO_ADMIN, TIMELOCK_PROTECTED, ZERO_DELAY_TIMELOCK_RISK, MULTISIG_NO_TIMELOCK, INSTANT_EOA_ADMIN_RISK, UNDEPLOYED_OR_EOA, UNCLASSIFIED_CONTRACT_CONTROLLER), a 0-100 risk score, proxy / admin / timelock breakdown and pause / blacklist / upgrade capabilities, pinned to a block hash.
- [https://pacta-x402.pacta.workers.dev/openapi.json](https://pacta-x402.pacta.workers.dev/openapi.json): OpenAPI 3.1 for ChatGPT Actions, LangChain and OpenAPI tools; every route takes GET query parameters or a POST JSON body. 60 requests / minute per caller; free during the launch (pricingMode free_launch), x402 v1 + v2 ready.

## Methodology
- Scanner seats replay read-only eth_call / eth_getStorageAt at the cited block (two independent archive RPCs); an isolated verifier seat re-checks selectors, EIP-55 checksums, EIP-1967 slots and arithmetic offline.
- Classifications: parameter_delta (on-chain differs from docs), protective_delta (a change that strengthens controls), aligned_baseline (on-chain matches docs), rpc_observed (on-chain control plane pinned at an archive block height over JSON-RPC; documentation parameter comparison unassessed).
- Exploit-sensitive vulnerabilities are never published here. They go through the protocol’s Immunefi or Cantina bounty programme, or to a partner audit firm under a 15% referral partnership.

## Access
- Free and real-time for everyone, including vault curators, allocators and AI risk agents: every indexed record, the timelock radar, the briefs, /api/v1/*.json and this file. No key, no delay, no paywall; curators never pay.

## x402 API (live; free during the launch)
- On-demand scans of contracts outside the index. Free launch: every route answers HTTP 200 at $0 with no payment header (pricingMode free_launch); the x402 flow below applies only when the operator switches pricingMode to x402_paid. Live gateway: https://pacta-x402.pacta.workers.dev (Cloudflare Worker, x402Versions [1, 2]: v1 network `base` with `X-PAYMENT` / `X-PAYMENT-RESPONSE`, v2 network `eip155:8453` with `PAYMENT-REQUIRED` / `PAYMENT-SIGNATURE` / `PAYMENT-RESPONSE`; USDC on Base, payTo `0xcA4E2ff22B69A7284210c47BdeE21Aac1269da09`, maxTimeoutSeconds 60). Routes (x402_paid prices): `GET /v1/check/preflight?chain=&address=` ($0.01), `GET /v1/scan/control-plane?chain=&address=` ($0.10), `GET /v1/scan/timelock-op?chain=&timelock=&opId=` ($0.25), `GET /v1/scan/proposal-diff?forum=&topicId=` ($0.15), `GET /v1/briefs/live-timelocks` ($0.10); free `/health`, `/.well-known/x402` (Bazaar discovery), `/v1/sample/control-plane`. A bare GET (no query) or zero-byte POST with no payment header on a paid route returns HTTP 402 with both challenges; the Bazaar extension carries a JSON Schema draft 2020-12 schema.
- Remote MCP: https://pacta-x402.pacta.workers.dev/mcp (free, no install). Local stdio server (from a clone of the repo; npm publication pending): set `PACTA_X402_URL=https://pacta-x402.pacta.workers.dev` to enable the scan tools; in x402_paid mode pay with `xPaymentHeader` (v1) or `paymentSignatureHeader` (v2). Settlement receipts are the facilitator's assertion (onchainReceiptVerified: false).
