instinct-advertiser

instinct-advertiser is a skill for Cursor from Dexter-DAO/opendexter-ide. It costs 74 tokens per session (1,878 once invoked), scanned A, original, MIT.

A workflow for creating and funding sponsored campaigns on Instinct, an advertising service for x402 APIs. An x402 API is a web service that charges an agent for each request, commonly using cryptocurrency.

In plain words
What is it for?
Use it to create an Instinct campaign, add a budget in USDC or DEXTER, activate it, or pay campaign costs through DEXTER.
Why use it?
It lets an API owner pay to have their service recommended to agents when matching paid API requests are settled. The campaign must be created, funded, and activated before it goes live.

Token cost

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.

Security

Grade A, and why

instinct-advertiser 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instinct Advertiser

Instinct is Dexter's ad exchange for agents. An advertiser funds a campaign; when an agent pays for any x402 API that matches the campaign's targeting, the campaign's recommendation rides back inside the settlement response. The agent sees the advertised API as a suggested next call.

This skill drives the advertiser side: create a campaign, fund it, activate it. The API is at https://x402ads.io/v1/agent and every call is x402-paid. The paying Solana wallet IS the advertiser identity. No signup, no API key.

When to use this skill

The user wants to:

  • Advertise an x402 API ("get my endpoint recommended", "promote my API to agents")
  • Run a sponsored campaign on Instinct
  • Fund or activate an existing campaign
  • Pay campaign budget in DEXTER for the discount

If the user wants to consume x402 APIs (search, pay, call), that is the opendexter skill, not this one. This skill is for the advertiser.

The campaign lifecycle

A campaign moves through four states. Each step is a separate x402-paid call.

create (draft, $0.10) -> fund (budget, USDC or DEXTER) -> activate ($0.01) -> live

A campaign created but not funded has zero budget and cannot be activated. A funded campaign that is not activated does not match anything. Both steps are required.

Tool routing

There is no dedicated campaign MCP tool. With OpenDexter, check each exact URL, method, and body while connected; show the current terms; obtain explicit approval for that campaign action and atomic ceiling; then call x402_fetch once with the returned opaque intentId and maxAmountAtomic. If the outcome is uncertain, call x402_status with the same intent and do not repeat the fetch. An independently built @dexterai/x402 SDK client is a separate authority surface, not an OpenDexter fallback.

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.
