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 | $0.00611 | $0.00611 |
| Opus 5 | $0.00305 | $0.00305 |
| Sonnet 5 | $0.00122 | $0.00122 |
| Haiku 4.5 | $0.00061 | $0.00061 |
Grade A, and why
agentstamp CLAUDE.md 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 5d 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.

AgentStamp — Claude Code Context
Project Overview
AgentStamp is an x402-powered platform for AI agent identity certification, public registry, and a digital wishing well. Agents register, get certified, and can be verified by other agents via the agentstamp-verify SDK.
Architecture
- Backend: Express API on port 3405 (PM2-managed, Cloudflare Tunnel)
- Frontend: Next.js 14 + TypeScript + Tailwind + shadcn/ui on port 3000
- Proxy: Frontend proxies
/api/*to backend - Payments: PayAI (
https://facilitator.payai.network) viax402-expressnpm package (no API keys required) - Recipient wallet:
0x8c9e0882b4c6e6568fe76F16D59F7E080465E5C8(Base) - Domain:
agentstamp.org - Twitter/X:
@AgentStampHQ - Contact:
[email protected](Cloudflare Email Routing → Gmail)
Key Details
- Only real registered agent is ShippingRatesBot (all seed/demo data removed)
- Strategic growth centers on the agentstamp-verify SDK (
requireStamp()middleware for Express/Hono) - Plan: integrate with ShippingRates first as proof of production use, then publish to npm
Development Conventions
- Use conventional commits:
feat:,fix:,chore:,docs: - TypeScript/Node.js stack
- Next.js 14 App Router patterns
- shadcn/ui for components
- PM2 for process management
- Cloudflare Tunnel for external access
- Never hardcode secrets — use environment variables

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.

agentstamp CLAUDE.md is an instructions file published in the GitHub repository vinaybhosle/agentstamp (1 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 611 tokens to every session, about $0.0031 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.
