# SolonPad

> Multi-chain memecoin launchpad and pad aggregator on Arc (chain 5042, native-USDC gas) and Robinhood Chain (4663), built to be operated by AI agents directly: no account, no API key, no frontend required. The machine interface is an open-source skill repo pinned by commit; the website is only a pointer to it.

Not available to persons or entities in the United States, China, or sanctioned jurisdictions.

## Machine interface (start here)

- [solonpad-skill](https://github.com/solonlend/solonpad-skill): the interface. SKILL.md routes you; AGENT-GUIDE.md has exact call sequences; VERIFY.md proves the contracts before you send value; addresses.json + abis/ + errors.json are the ground truth. Pin a commit hash, never trust a live endpoint.
- [For-agents page](https://solonpad.fun/agents): quickstart, live request counters and paid-call revenue (settled payments only).

## Free API (read layer)

- [Launches](https://solonpad.fun/api/launches?chain=arc): every pool across all indexed pads (SolonPad, Pons, pools.trade, Minara, Azex, all native-USDC v4 pools).
- Changes: `GET /api/changes?chain=arc|rh&since=<cursor>` — incremental discovery, opaque cursor, 200 events/page.
- Factsheet: `GET /api/factsheet/{token}?chain=arc|rh` — one-call due-diligence data with tri-state fields (`unavailable` means unknown, never zero).
- OHLCV: `GET /api/ohlcv?chain=&token=&tf=` — free tier, 200 candles.

## Paid API (x402, no signup)

Payment is in-band: HTTP 402 challenge → sign one EIP-3009 USDC TransferWithAuthorization on Arc → retry with the payment header. Client: `tools/x402-pay.mjs` in the skill repo; prices pinned in `tools/x402-prices.json`. Launch offer: 50% off list, already in the wire amounts.

- [OpenAPI spec](https://solonpad.fun/openapi.json): the full machine-readable contract for every paid endpoint, including the 402 challenge schema.
- [RPC credits page](https://solonpad.fun/rpc): $1 = 10,000 JSON-RPC calls across all four chains, bearer voucher, copy-paste buy flow.
- Verdict $0.01: `GET /api/premium/verdict/{token}?chain=arc|rh` — factsheet + calibrated verdict + rail DD.
- Batch verdicts $0.20: `POST /api/premium/verdicts` — up to 50 tokens, one chain.
- Deep OHLCV $0.02: `GET /api/premium/ohlcv?chain=bsc|sol` — up to 5000 candles, honest truncation flags.
- Changes $0.05: `GET /api/premium/changes` — 1000 events/page.
- RPC credit pack $1: `POST /api/premium/rpc-credit` — 10,000 JSON-RPC calls across Arc/BSC/Robinhood/Solana, one bearer voucher, `Authorization: Bearer` on `/api/rpc/{chain}`.

## Execution (bring your own wallet)

- Launch, buy, sell on Arc/RH curves and v4 pools: AGENT-GUIDE.md §V4, §0–§6.
- Cross-pad trading through SolonFeeRouter (0.5% interface fee): §Aggregator.
- Cross-chain rail — fund on Arc USDC, execute on BSC/Solana/Robinhood/Arc, one signature in single-sig mode, non-custodial: §E.
- Premium data plane details, settlement semantics, voucher rules: §F.

## Optional

- [Solon Lend](https://github.com/solonlend/skill): separate product — leveraged tokenized-stock lending on Robinhood Chain.
