Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01218 |
| Opus 5.5 | $0.00023 | $0.00487 |
| Sonnet 5.5 | $0.00012 | $0.00244 |
| Haiku 4.5 | $0.00006 | $0.00122 |
Grade A, and why
sera-protocol scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Load the relevant reference
The bundled references retain the detailed implementation material from the
original sera-protocol Skill. Read only the file that matches the task; values
such as contract addresses, endpoints, supported assets, tool inventories, and
deployment status can change, so verify them against the linked official source
or the configured service before using them in a live integration.
| Task | Read |
|---|---|
| Current REST API, quotes, swaps, orders, or Virtual Liquidity | references/api-reference.md |
| v1 subgraph queries and order-book data | references/graphql-api.md |
| v1 Router / PriceBook contract integration | references/smart-contracts.md |
| v2 signed orders, Vault, SOR, or batch matching | references/orderbook-v2.md |
| Trading front-end patterns | references/frontend-patterns.md |
| Official or sample MCP server configuration | references/mcp-server.md |
| Sera Agents templates or x402 | references/sera-agents.md |
| SeraPay merchant payments | references/sera-pay.md |
Start with the right surface
Pick the least privileged integration that solves the task.
| Need | Recommended surface |
|---|---|
| Rates, corridors, and a settlement intent | The hosted, keyless MCP gateway at https://agents.sera.cx/mcp |
| Treasury, orders, or execution workflows | A locally run or self-hosted sera-mcp with an explicit signer mode and policy |
| A new AI-agent product | One of the sera-agents templates |
| Machine-to-machine 402 payment flow | Self-host x402-service; demo mode is local-only |
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
