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.

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 | $0.00074 | $0.01878 |
| Opus 5 | $0.00037 | $0.00939 |
| Sonnet 5 | $0.00015 | $0.00376 |
| Haiku 4.5 | $0.00007 | $0.00188 |
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 11d 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.
| The user wants | Call |
|---|---|
| Know the exact campaign fields before building one | GET /v1/agent/campaigns/schema (free) |
| Know how funding works | GET /v1/agent/escrow (free) |
| Create a campaign | POST /v1/agent/campaigns ($0.10 USDC) |
| Add budget to a campaign | POST /v1/agent/campaigns/{id}/fund (the payment is the budget) |
| Make a funded campaign eligible | POST /v1/agent/campaigns/{id}/activate ($0.01 USDC) |
| See a campaign's stats / conversions | GET /v1/agent/campaigns/{id} ($0.01 USDC) |
| List the wallet's campaigns | GET /v1/agent/campaigns ($0.01 USDC) |
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.

instinct-advertiser is a skill published in the GitHub repository Dexter-DAO/opendexter-ide (2 stars, last pushed 6d ago), licensed MIT. It adds 74 tokens to every session and 1,878 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
