README

TruePoint Prospect Intelligence & Claim Grounding

Pay-per-call APIs for AI agents. Pay USDC on Base per call with x402. No API key, no signup. People can pay by card instead.

  • Prospect Intelligence: work-email lookup and company research for sales agents.
  • Claim Grounding: checks factual claims against public sources and returns a verdict, confidence and citations.

Accuracy results: https://claim-grounding.prospectintel.workers.dev/accuracy (92 of 100 hard claims right on Deep verify, 0 confidently wrong; 38 of 38 found emails exactly right). Read the limitations there too.

30-second quickstart

Option A: Coinbase agentic wallet (awal)

bash
npx awal@latest status          # sign in / check walletnpx awal@latest balance         # needs USDC on Basenpx awal@latest x402 pay https://claim-grounding.prospectintel.workers.dev/v1/verify_claim \  -X POST -d '{"claim":{"text":"The Eiffel Tower is in Paris"}}' --max-amount 1000000

--max-amount is in USDC atomic units (1000000 = $1.00), so you can never pay more than you set.

Option B: any x402 client. Call the endpoint with no payment. You get HTTP 402 with the price in the body and a payment-required header. Sign the payment with your x402 client and retry. Settlement uses the Coinbase CDP facilitator on Base (eip155:8453).

Option C: MCP. Point an MCP client (streamable HTTP) at:

  • https://claim-grounding.prospectintel.workers.dev/mcp
  • https://prospect-intelligence.prospectintel.workers.dev/mcp

tools/list is free. Tool calls return x402 payment instructions; the paid HTTP route does the work.

Option D: pay by card (people). Stripe checkout, no wallet needed:

ProductPriceLink
Claim check$0.50https://buy.stripe.com/00w5kDcBN8ri9Go6NP0co02
Deep verify$2.00https://buy.stripe.com/9B614n1X9bDuf0I2xz0co06
Email lookup$0.50https://buy.stripe.com/4gMcN56dp36Y05O4FH0co05

Card prices are higher than agent prices because Stripe has a $0.50 minimum and per-charge fees.

Sample request and response

Request (real, paid, Oct 12, 2026):

bash
npx awal@latest x402 pay https://claim-grounding.prospectintel.workers.dev/v1/verify_claim \  -X POST -d '{"claim":{"text":"The Eiffel Tower is in Paris"}}'

Response (HTTP 200, shortened with …):

json
{  "mode": "fast",  "job_id": null,  "claim": {    "claim_id": "clm_14b3ffa736fd4fd1",    "text": "The Eiffel Tower is in Paris",    "span": { "start": 0, "end": 29 },    "grounding_required": true,    "verdict": "supported",    "status_detail": "supported",    "confidence": 0.95,    "citations": [      {        "url": "https://en.wikipedia.org/wiki/Eiffel_Tower",        "title": "Eiffel Tower",        "quote": "The Eiffel Tower is a lattice tower on the …",        "retrieved_at": "…",        "provider": "wikipedia"      }    ],    "rationale_short": "…"  },  "why": "…",  "source": "https://en.wikipedia.org/wiki/Eiffel_Tower",  "receipt": { "claim_hashes": ["sha256:…"], "evidence_urls": ["https://en.wikipedia.org/wiki/Eiffel_Tower"], "verdicts": ["supported"], "priced_usd": 1, "created_at": "…" }}

Paid on Base: tx 0x839f…a901.

The unpaid first call (real, live) returns HTTP 402:

json
{  "x402Version": 2,  "error": "Payment required",  "accepts": [{    "scheme": "exact",    "network": "eip155:8453",    "amount": "80000",    "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",    "payTo": "0x485FfC037f02dDDc154A454a9cA89C4B1b29e25b",    "maxTimeoutSeconds": 300,    "extra": { "name": "USD Coin", "version": "2" }  }]}

(80000 = $0.08 for /v1/email. The asset is USDC on Base.)

Errors

StatusWhenCharged?
200SuccessYes
402No or invalid payment. Body and payment-required header list what to payNo
400Bad input, e.g. missing claim.text, or mode: "deep" sent to verify_claim (use /v1/deep_verify). On email: missing domain or namesNo
404Email lookup found no address (no_result), unknown path, or unknown job idNo
405Non-POST request to /mcpNo
409Card payment already used for a lookup (one payment = one lookup)No
422Email provider rejected the input (e.g. domain has no mail records)No
451Email lookup: the person opted out of data processing. Do not contact or storeNo
502 / 503Upstream source or email provider unavailable. Safe to retry laterNo

x402 only settles payment on a 2xx response, so failed calls cost nothing.

What these tools don't do

  • Not legal, medical, financial or compliance advice. Not a certification.
  • English only. Public sources only; no paywalled or private documents.
  • Can return insufficient_evidence. Very recent news may lag.
  • No guarantee an email is delivered or read. No personal/private emails, no phone numbers.
  • Decision-makers are unknown unless a public source names them. Nothing is invented.
