# TENNA Launch Intelligence – Launch Cohort Base Rates

> TENNA Launch Intelligence – Launch Cohort Base Rates is a paid API for AI agents from app.tenna.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns historical base rates for a given launch cohort (e.g. memecoins, virtual-quoted tokens), including median terminal multiple, profitable-exit rate, and severe-loss frequency — background statistics only, no token-specific signals.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tenna-launch-intelligence-launch-cohort-base-rates-4598e6f0 -d '<json body>'
```

Example prompt: Pull the TENNA launch cohort base rates for the memecoin cohort — I want to see the median terminal multiple, profitable-exit rate, and severe-loss frequency for comparable launches.

## When to prefer this

Use this endpoint when you need population-level historical context about how a class of token launches (memecoins, virtual-quoted, or unclassified) has historically performed — median multiples, win rates, and loss frequencies. Prefer this over token-specific endpoints when you want background base rates rather than evidence on a specific launch. Do not use this for real-time monitoring, individual token verdicts, or trading signals.

## Known failure modes

- Invalid cohort enum value returns a validation error
- offering field not set to 'launch_cohort_baseline' returns an error
- Payment not provided or insufficient USDC results in 402 payment required
- Network or server downtime returns 5xx error
- Missing required fields returns 400 bad request

## How this service works

Launch Cohort Base Rates. Base rates for a launch family: how comparable launches ended (median terminal multiple, profitable rate, severe-loss frequency). Shared background only; never a token-specific verdict. No trading signals.

## Output

Returns cohort-level historical statistics including median terminal multiple (how much value tokens in this cohort gained or lost by final measurement), the profitable-exit rate (fraction of launches where holders could exit in profit), and severe-loss frequency (fraction ending in near-total loss). These are population-level background rates, not predictions or signals for any specific token.
