Eichor API — clinical trial risk intelligence for developers & AI agents

Per-call clinical trial risk intelligence — for your code and your AI agents. Eichor computes site-risk signals from public evidence (ClinicalTrials.gov, FDA, SEC EDGAR, CMS) and serves them as a simple paid API: one question, one credit, one machine-readable answer with its sources named. No sales call, no subscription required, no scraping of anyone's private systems.

REST endpoints

GET /api/v1/risk-score?nct_id=NCT… — composite trial distress score (0–100 + tier) with the headline driver.
GET /api/v1/geo-risk?city=&state=&country= — geographic patient-retention risk for a location.
GET /api/v1/feasibility?area=&region= — indication-level feasibility grade for a therapeutic area.
GET /api/v1/usage — your balance and quota (free).

Auth is a single header. Try it:

curl -H "X-Api-Key: YOUR_KEY" "https://eichor.com/api/v1/risk-score?nct_id=NCT05664217"

Example answer:

{"composite_score": 18, "composite_tier": "LOW",
 "top_driver": "Trial is past its enrollment phase (Terminated…) — distress capped.",
 "driver_count": 4, "recruitment_healthy": false,
 "source": "Computed from public evidence (ClinicalTrials.gov, SEC EDGAR, FDA)…"}

Machine-readable schema with the full contract: /api/v1/schema · discovery file: /llms.txt

MCP server (for AI agents)

The same intelligence is a native Model Context Protocol server at https://eichor.com/mcp (streamable HTTP). Five tools: risk_score, geo_risk, feasibility, usage, and buy_credits — the last one needs no key at all, so an agent with no account can initiate its own signup. Auth: Authorization: Bearer <key> or X-Api-Key. Browsing tools/list is free.

See a machine do the whole thing

A sealed, replayable session of an AI agent with no key and no money discovering this channel, earning credits with verified work, and spending them on a live call: watch the transcript. (Our own demonstration agent, honestly labeled — the transcript hash is sealed in our attestation ledger, so it can't be edited after the fact. Everything it does, your agent can do.)

Buy self-serve: POST /v5/exodus/api-credits/checkout {"email", "pack"} returns a Stripe checkout link; your API key and quickstart are emailed on payment. Credits are prepaid and non-refundable once consumed. Every response carries your remaining balance in its headers. Subscription plans include monthly API quota — see pricing.

What the API deliberately doesn't include: the full driver decompositions, milestone-drift forensics, per-site A–F grades, named alternative sites and 24/7 monitoring are part of Eichor's subscription products. The API tells your system whether something is wrong; the platform tells your team why, and what to do about it.

Fair-use guardrails: per-key rate limit (60 calls/min), per-entity answers only. Every answer derives from public-domain data and names its sources — nothing scraped from private systems, no patient-level data. Questions: hello@eichor.com.
