Messari's API serves analysts and agents that need structured, historical deal and entity data for the crypto ecosystem. It covers three distinct data types: organization metadata (founding dates, sectors, locations, external links), M&A events (acquirer/target profiles, deal values, statuses), and funding rounds (stage, amount, investor IDs, token vs. equity). It does not provide token prices, on-chain data, or individual record lookups by ID.

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 4 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 3 routes are in the 50–74 band — working, but with room to climb.
- 5 routes are flagged by the verifier as failing or inconclusive.

Make my x402 API at https://api.messari.io discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://api.messari.io --json`. Heads up: 4 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
