# Treasures B2B API — Agent Skill

Guide for AI agents (and any non-human caller) using the Treasures public B2B API to discover tokenized stocks, quote + execute trades, bridge USDC across chains, and read portfolio + trade history on behalf of a single end-user wallet pair.

- **Base URL:** `https://api.treasures.io/public/v1`
- **Network:** trades execute against **Ethereum mainnet + Solana mainnet-beta — real funds, not a testnet**. Point your own RPCs at mainnet; the token/contract addresses in this skill are mainnet.
- **Required headers:** set `Content-Type: application/json` on every request carrying a body — a body sent with a **non-JSON** content-type (e.g. `text/plain`, which some HTTP clients default to when you don't set headers) fails `415` before any schema check. Also send `X-Treasures-Skill: treasures-b2b-api` and `X-Treasures-Skill-Version: 1.2.0` (this skill's `metadata.version`): today they're informational (the fund-moving endpoints echo `X-Treasures-Api-Revision` + `X-Min-Skill-Version` back), but once the API floor rises, an enrolled caller below it gets a clean `426 skill_version_unsupported` with upgrade instructions — plus `Deprecation`/`Sunset` warning headers during the grace window — instead of a silent break. Omitting the version header opts out of that early warning.
- **Wire format:** all token amounts, USDC, shares, prices, and bps-derived decimals are **strings** (avoid JS float drift). Integer fields (`expires_at`, `*_bps`, `quote_index`) are JSON numbers. Never round-trip a money value through JS `number`.

This entry doc is the map + the footguns. **It is not enough on its own to execute a trade** — full schemas, signing code, and error tables live in the references below. **Load the reference for the task before you act; you don't need to read them all.**

> **Schema-of-record:** an OpenAPI spec (`openapi.yaml`) is published alongside this skill in the same repository. This skill is self-sufficient for normal use — consult the spec only for exhaustive field-level validation or client codegen; you don't need to read it to operate.

## TL;DR — happy path

```
1. GET   /stocks/tickers              → supported tickers + token addresses
2. GET   /stocks/prices?tickers=AAPL  → live price snapshot
3. ONE-TIME:
