# Jell documentation

> One API for everything your agent needs to grow a company: discover a
> capability, inspect its exact price, run it, settle against one prepaid
> wallet. Every page below is available as markdown at the .md URL.

## Get started

- [How it works](https://jell.run/docs/how-it-works.md): One key, one wallet, and the discover, inspect, run loop behind every call.
- [Quickstart: API](https://jell.run/docs/quickstart-api.md): A first REST call in five minutes: signup, inspect, run, wallet.
- [Quickstart: CLI](https://jell.run/docs/quickstart-cli.md): The plain-text CLI that mirrors the API one-to-one, built for agents.
- [Quickstart: agents (SKILL.md)](https://jell.run/docs/quickstart-agents.md): Add lead enrichment, SEO, social and outbound tools to Claude Code, Codex, Cursor or any agent with one SKILL.md (Agent Skills) instead of writing API wrappers: discover, inspect and run, with the spending rules built in.
- [Quickstart: MCP server](https://jell.run/docs/quickstart-mcp.md): Connect the Jell MCP server to Claude Code, claude.ai, ChatGPT, Cursor, VS Code or your own agent on the Claude or OpenAI API: SERP, backlink and keyword data, B2B contact and company enrichment, social scraping and outbound as native tools on one balance.
- [Find people at the right company](https://jell.run/docs/people-search.md): Use employer domains, title filters and current-role evidence to build a better people list, then find emails only for the profiles you need.

## API reference

- [WhatsApp and Gmail](https://jell.run/docs/connected-accounts.md): Connect WhatsApp or Gmail, send messages and email, read replies, and manage connected accounts.
- [API overview](https://jell.run/docs/api/overview.md): Base URL, authentication, environments, the error envelope and idempotency.
- [Discover](https://jell.run/docs/api/discover.md): POST /v1/discover: search capabilities and raw endpoints by job description. Free, never runs a paid call.
- [Inspect](https://jell.run/docs/api/inspect.md): POST /v1/inspect: a capability's schema, providers and exact price, or a raw endpoint's contract and cost model.
- [Run](https://jell.run/docs/api/run.md): POST /v1/run: execute a capability with routing and failover, or a raw endpoint under max_cost.
- [Raw endpoints](https://jell.run/docs/api/endpoints.md): Provider + endpoint addressing for the long tail: the provider's own request and payload, settled on the provider's measured cost after the run.
- [Runs](https://jell.run/docs/api/runs.md): GET /v1/runs: list, fetch and cancel runs; every attempt and charge on record.
- [Watch and refresh](https://jell.run/docs/api/watch.md): POST /v1/watch: save a query, refresh it weekly and get back only the new and changed records.
- [Wallet](https://jell.run/docs/api/wallet.md): Balance, transactions, top-ups, auto top-up and referrals on one prepaid wallet.
- [API keys](https://jell.run/docs/api/keys.md): Mint, list and revoke keys. Keys are hashed at rest and shown once.
- [Errors](https://jell.run/docs/api/errors.md): Stable error codes, HTTP statuses, the error envelope and retry guidance.
