# Unstuck

> Every failed Solana transaction, explained. Unstuck reads a mainnet transaction and says what happened in plain words, what it cost and what to do next, with a fix an agent can apply (parameters, never a transaction). Live today: the web explainer and an HTTP API, free during the beta, no key.

## Live HTTP API (free in beta, no key)
- Base URL: https://www.unstucksol.com/api
- Explain a transaction: `GET https://www.unstucksol.com/api/explain?sig=<signature or explorer link>` (or `POST /api/explain` with `{"signature":"..."}`)
- Try it: `curl 'https://www.unstucksol.com/api/explain?sig=3cbDDFD5GrPVzJZCfP8ppSGiTFHd6RHQBbgkrgRpXLbu2fbSPdKdgjimJduvMhRP3N8yh6QznSmtSVbh3feUwV2R'`
- Error catalog: `GET https://www.unstucksol.com/api/errors?q=<text>`
- Rules for agents: apply `fix` only when `fix.safe` is true, retry at most twice, otherwise stop and ask a person.

## For agents
- [Agent quickstart](agents.html): the self-healing loop, curl and fetch, price
- [API docs](docs.html): request, responses, every response field, limits
- [OpenAPI](agents/openapi.yaml): the two live endpoints
- [SKILL.md](agents/SKILL.md): portable skill that calls the live HTTP API

## For people
- [Try it on a transaction](index.html#how-it-works): paste a signature, no sign-in
- [App](app/index.html): sign in with a Solana wallet, explain transactions, free during the beta
- [Error catalog](docs.html#catalog): raw error, plain answer, typical fix
- [Pricing](index.html#pricing): planned prices; everything is free in beta

## Trust
- [Security model](security.html): read-only chain analysis; no keys, no signing, no custody, no payments
- [Changelog](changelog.html)

## Planned (not live)
- Paid tier over x402: 0.10 USDC per explain call, USDC on Solana (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v), network solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp. Beta: calls are free; the x402 flow is the planned paid tier and is not enforced.
- MCP server and skill package: use the HTTP API today (curl / fetch); they ship when the API leaves beta. [Planned server card](agents/mcp.json)
- Team plan (support inbox, hand-offs): private beta, DM https://x.com/unstuck_sol
