Eventyay is an open-source platform for managing events, including ticket sales and registration, speaker submissions, session schedules, videos, check-ins, badges, exhibitions, and organiser administration. Event organisers use it to run both in-person and online event workflows.

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 | $0.00132 | $0.02080 |
| Opus 5.5 | $0.00053 | $0.00832 |
| Sonnet 5.5 | $0.00026 | $0.00416 |
| Haiku 4.5 | $0.00013 | $0.00208 |
Grade A, and why
metronome 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 17d 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.
This is a copy
100% identical to metronome — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Metronome API base: https://api.metronome.com. Authenticate with a Bearer token in the Authorization header. Always use Contracts (not legacy Plans) for new integrations.
Integration routing

Send usage events, the API quickstart, the Ingest API reference, and Set ingest aliases |
| Defining what to measure | Billable Metrics API | Create billable metrics |
| Enterprise pricing agreements | Contracts + Rate Cards | Provision a customer contract, Create and manage rate cards, and the Create a contract and Add rates API references |
| Mid-term contract changes | Contract Edits | Edit a contract, Contract edits and overrides, and Manage contract lifecycle |
| Invoice lifecycle and finalization | Invoices API | How Metronome invoices work |
| Prepaid or postpaid commitments and one-off top-ups | Commits + Credits | Apply credits and commits to contracts and Payment-gated commits |
| Syncing invoices to Stripe | Stripe billing provider config | Invoice with Stripe |
| Prepaid balances, auto-recharge, spend alerts, and thresholds | Notifications API | Set prepaid balance thresholds, Enforce spend thresholds, and Threshold notifications |
Read the linked page before answering any integration question or writing code; the links return plain Markdown. If no row fits, use the documentation index to find the right page, and append .md to the page URL to fetch it as Markdown.
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.
